Unlike many of my San Diego Zoo Global (SDZG) colleagues that have traveled to China, I wasn’t sent there to accompany one of our young pandas on their journey home. The beautiful and green-certified facility is located on 125 acres along the foothills of the bamboo forest and currently houses almost 30 giant pandas. The beautiful facility was just the right venue for participants to sharpen their necropsy skills.
The pathology workshop was comprised of 25 Chinese veterinarians, managers, and technicians from 18 different panda facilities throughout China, as well as 4 interpreters and 9 instructors from various international facilities. These tools and techniques will help the Chinese determine the best conservation strategies for the giant panda populations in China. This is just another great example of how the San Diego Zoo is helping the fight against extinction globally.

The Wildlife Disease Laboratories of the San Diego Zoo Institute for Conservation Research and the San Diego Natural History Museum (SDNHM) have had a long-time working relationship. Having never necropsied a whale and being unfamiliar with the anatomy, I thought it would an amazing experience.
As you would expect, Scott and his volunteers made many more trips to the beach to recover as many bones as possible, stacking them at the base of the cliff. April Gorrow is a senior pathology technician at the San Diego Zoo Institute for Conservation Research.
As most of you know, giant panda Gao Gao had surgery May 6, 2014, to remove his right testicle after a tumor was discovered by our veterinary staff (see Surgery for Gao Gao). After we received Gao Gao’s testicle in the laboratory, parts of the tumor were processed and stained for examination under a microscope. This photomicrograph (taken through a microscope) shows the tumor on the right-hand side compressing the normal testicular tissue on the left. We also used a specialized technique, immunohistochemistry, to determine if the tumor was making substances characteristic of one particular cell type or another. In Gao Gao’s case, the evidence supports a diagnosis of seminoma, which is a tumor arising from the germ or sperm-producing cells. This high magnification photomicrograph shows a single tumor cell undergoing mitosis (cell division), a characteristic that indicates tumor growth. Despite this uncertainty, we are very hopeful that Gao Gao’s tumor will behave more like a seminoma in dogs.
2Beware of Crunchy Figs!By April Gorow – January 16, 2014The fruit of a Ficus sansibarica provides a cozy home for fig wasps. Recently, the Wildlife Disease Laboratories received an interesting request from Seth Menser, a senior horticulturist at the San Diego Zoo, asking if we could take pictures of plant parts under the microscope. Seth brought up several figs from a Ficus macrophylla, commonly known as a Moreton Bay fig.
Ficus trees are unique because the flowering parts of the plants are inside the fruiting parts (figs), making it difficult for insects to pollinate the trees. To begin the cycle, a tiny female fig wasp enters into a narrow opening (ostiloe) at one end of the fig. April Gorow is a senior pathology technician with the San Diego Zoo Institute for Conservation Research.
3We Never Stop LearningBy April Gorow – September 3, 2013Did you know that hedgehogs evolved 50 million years ago in San Diego County?
Dioramas, specimen jars, and stacks of books are all images that come to mind when you think of natural history museums. We have established how important museums are, but where does the museum get their specimens?

Compared to the numerous mammalian species you normally encounter, such as dogs and cats, desert tortoises have relatively limited means of expression. When your physician does an exam, simply asking you questions makes the task much more straightforward.
By carefully pressing fingers into the soft skin area near the hind legs and into the shell cavity, an experienced examiner can determine whether there are masses in the coelomic cavity. Identifying unhealthy tortoises is an important task at the San Diego Zoo’s Desert Tortoise Conservation Center in Las Vegas for individual animal and population health.
1The Social Network…of BirdsBy Carmel Witte – June 25, 2013These two bee-eaters sharing a meal in their aviary are part of the same social network. The age of social networking has the world communicating through cyberspace on just about anything. Scientists are developing new methods to understand how people are influenced by their social network. Avian mycobacteriosis is a bacterial disease of birds caused by Mycobacterium avium and other related species of mycobacteria. We are just beginning this fascinating journey into understanding the influence of social networks on disease dynamics in our animals, so you will have to stay tuned to find out the answers. 5Blue-chinned Sapphire MysteryBy Rachael Holland – June 21, 2013Males have the bright blue plumage, while females are a bit less striking. But when our veterinary pathologists looked under the microscope at the tissues from the birds, they made a Eureka! Rachael Holland is a research technician at the San Diego Zoo Institute for Conservation Research’s Wildlife Disease Laboratories.
0Veterinarians Don’t Just Operate, They Educate!By Valerie Stoddard – June 7, 2013Yes, veterinarians even examine panda cubs! For veterinarians at San Diego Zoo Global, in addition to caring for the animals in our collection, one of the most important things they do is share their vast knowledge and expertise with aspiring veterinary students at the university level.
In 2003, our veterinarians and pathologists collaborated to create an externship program, and since then it has grown exponentially. As with specialties in human medicine such as cardiology or orthopedics, zoo veterinary medicine is a specialty where focused training and education is required. Once a veterinary student has chosen zoo medicine as a field of interest, applying for and participating in an externship rotation is an important step toward success.
Our veterinary student externs must be in their fourth or senior year during their rotations. While it takes a great deal of initiative, discipline, leadership skills, and patience, working as a veterinarian in a zoo setting is also extremely rewarding. I’m a veterinary pathologist, which means I spend a lot of quality time looking through a microscope at slides with tissues to try to evaluate health problems that show up as changes in those tissues.
At the San Diego Zoo Institute for Conservation Research, I work exclusively on tortoises that have died at the Desert Tortoise Conservation Center. To get information from enough tortoises to allow good conclusions to be drawn, I need to look at a lot of slides. Tweet Como siempre veamos lo que nos dice nuestro manual de cabecera: El Control de las enfermedades transmisibles en el hombre. La varicela es una virosis aguda generalizada, de comienzo repentino, con fiebre moderada, sintomas generales leves y una erupcion cutanea maculopapulosa que dura pocas horas y se transforma en vesiculosa durante tres o cuatro dias y cuando se secan las vesiculas  deja costras granulosas.
Las lesiones tienden a ser mas frecuentes en las partes cubiertas del cuerpo que en las descubiertas. La varicela es una enfermedad benigna de la infancia, en algunas ocasiones pueden aparecer complicaciones como neumonia, encefalitis, que a veces dejan secuelas permanentes o causan la muerte. Las sobreinfecciones bacterianas de las vesiculas pueden dejar cicatrices u ocasionar fascitis necrosante o septicemia.
Si la infeccion ocurre durante las 20 primeras semanas de embarazo, podria dar lugar un Sindrome de varicela congenita, aproximadamente en un 0,7% de los casos. El Virus de la Varicela Zoster (VVZ) se acantona en los ganglios de las raices dorsales y, en ocasiones, puede reactivarse una infeccion latente apareciendo una lesion local denominada Herpes Zoster. El herpesvirus humano 3 (alfa), tambien conocido como el virus de la varicela-zoster (VVZ), miembro del grupo Herpesvirus.
El modo de transmision de persona a persona por contacto directo, por gotitas respiratorias o por diseminacion aerea de secreciones de las vias respiratorias de los pacientes o del liquido de las vesiculas; indirectamente por objetos recien contaminados con secreciones de las vesiculas y las mucosas de las personas infectadas. La varicela es una de las enfermedades mas facilmente transmisibles, en especial durante las primeras etapas de la erupcion.
El periodo de transmisibilidad, generalmente comienza uno o dos dias antes de la erupcion de varicela y dura hasta que todas las lesiones esten en fase de costras: unos cinco dias despues de que aparece el primer brote de vesiculas. Vacuna contra la varicela de virus vivos atenuados: 1 dosis de 0,5ml por via subcutanea a los a los 15 meses y un refuerzo vacunal a los 11 anos de edad. La vacuna esta contraindicada en personas inmunodeprimidas, embarazadas, enfermedad grave y trastornos inmunitarios graves. Exclusion de los ninos de la escuela, consultorios medicos, salas de urgencias y sitios publicos durante cinco dias como minimo despues de que aparece la erupcion o hasta que se secan las vesiculas. El aislamiento estricto en los hospitales e indispensable para evitar la infeccion grave de los pacientes inmunodeficientes. La inmunogobulina varicela-zoster (IGVZ), preparada a partir del plasma de donantes de sangre normal con altos titulos de los correspondientes anticuerpos especificos es eficaz para modificar o prevenir la enfermedad siempre y cuando se administre dentro de las 96 horas siguientes a la exposicion.

EN LA GUARDERIA DE MI HIJO HAY BROTE DE VARICELA SEGUN LA DIRECTORA YA SE TOMARON LAS MEDIDAS CORRESPONDIENTES Y NOS COMENTO LA DR. Alguien por favor diga cuanto dura el ciclo del herpes zoster en la piel, tengo a mihija de 4 años y a mi esposa y cuan contagiosa es? Que posibilidades hay que me de esta enfermedad, de niña me imagino que si me debe haber dado varicela, en realidad no recuerdo. Dia a dia vamos viendo el resultado para que mas personas se informen sobre esta enfermedad y un poco ayudarlas en esta etapa que muchas veces no sabemos que hacer. PUES BIEN APROVECHO ESTE FORO PARA PROMOVER UN PRODUCTO MARAVILLOSO QUE REFUERZA EL SISTEMA INMUNOLOGICO YA QUE SI NUESTRO SISTEMA INMUNE ESTA DEBIL ES UNA DE LAS CAUSAS POR LA CUAL NO TERMINA DE CURARSE EL HERPES ZOSTER. Buenas,ya que he entrado a este apartado no me voy a ir sin escribir mi experiencia con la varicela.
Me dijo que a mi edad iva a ser bastante molesta,porque suele ser una enfermedad de la infancia,pero bueno..
A mi esposo le empezo a doler la cabaeza del lado izquierdo y en la parte superior del labio izquierdo el domingo en la tarde y ya el lunes traia unos granos como urticaria, fue a la dermatologa y le dijo que era herpes zosters y que tomara por 7 dias el aciclovir, pero despues se le empezo a hinchar mas la cara lado izquierdo, el no se acuerda ni su mama si de chico ya le habia dado varicela. Mi pregunta es le dio por tener bajas las defensas, por tension o porque, aunque el desde chico a padecido soriasis y se que es del sistema nervioso. Le puede regresar, es contagioso, porfavor lo mas pronto posible si me puede contestar se le agradezco. HOLA, soy una mujer de 52 anos que atravieza por el virus de herpes zoster, con toda la sintomatologia que este padecimiento acompana, me afecto la parte inguinal, el parte del puvis, parte de la pierna junto a la cadera y se extendio hasta la parte de la nalga; todo esto empezo los primeros dias del mes de octubre, hoy ya es primero de noviembre, y sigo en tratamiento medico con los medicamentos ya descirtos, para este padecimiento, y sigo gastando en medico y medicamentos, mi pregunta es ? HOLA- TENGO TODOS LOS SINTOMAS DEL HERPES SOSTER, FUE LO QUE ME DIAGNOSTICO EL MEDICO Y ME DIO ACICLOVIR Y DICLOFENCO CON COMPLEJO B, PERO AM I NO ME HAN SALIDO AMPULAS SOLO TENGO UNA MANCHA ROJIZA EN LA ESPALDA, PERO ESO SI, QUEMA Y DUELE MUCHO HASTA EL BRAZO Y PARTE DEL PECHO DERECHO.. Evitar contagios de persona a persona por la saliva esta en nuestras manos.No tenemos que compartir envases,pero si en algun momento lo hacemos,no hay que chupar donde la otra persona lo ha hecho,si no disponemos de vasos se tiene que usar una Boquilla Personal,son de uso individual y evitan la transmision de enfermedades por la saliva de persona a persona.

El viernes 31 decidi pedirle a mi esposa que lidere cuidandola y que yo la ayudaba en sus cosas y cuidaba a la bebita, le pedi que se lave las manos, que no permita acercamientos con la bebita y algunas otras recomendaciones porque a mi no me habia dado, ella no lo ve tan delicado como lo es en realidad ya que hay casos que nadie desea que le toque el peor. Sugiero a los Padres que demostremos el amor a nuestros hijos con hechos, esto puede evitarse.
Me realiza unas pruebas de esfuezo ,en el dedo gordo afectado,en todos los dedos de la mano y en el brazo y comprueba la perdida de fuerza. CREO TENER EL VIRUS DE HERPES ZOSTER POR QUE TENGOS UNAS BERRUGUITAS Q PARECEN COMO LLENAS DE AGUA Y ARDEN MUCHISIMO Y NO SE ME CALMA EL ARDOR Y LA PICAZON CON NADA, YE EMPEZE CON EL TRATAMIENTO QUE RECETO EL DOCTOR QUE FUE APLICARME ACICLOVIR EN UNGUENTO Y TOMAR LAS MISMAS PASTILLAS CADA 6 HORAS PERO AUN NO VEO RESULTADOS Y LO QUE VEO ES QUE CADA VEZ TENGO MAS BROTE YA LLEVO 6 DIAS CON ESTE BROTE SI ALGUIEN SABE DE ALGO QUE ME AYUDE A SANAR ESTO RAPIDO SE LO AGRADEZCO YA QUE EL ARDOR EN MI ESPALDA Y PECHO SON INSOPORTABLE.

The herpes simplex virus is one of the herpes, DNA viruses that are important in causing human disease.
It is "composed of an inner core containing linear double-stranded DNA, surrounded concentrically by an icosahedral capsid of approximately 100 nm, an amorphous layer termed the tegument, and an outer envelope composed of lipids and glycoproteins." (Paula W.
Using the Baltimore classification (which is based on the mechanism of mRNA production) is a Group 1 virus (dsDNA) from the family Herpesviridae, subfamily Alphaherpesvirinae, Genus Simplexvirus and Species Herpes simplex virus 1.
Herpes can be found throughout human history by reading texts from the past that describe the characteristics of the fever blisters. In addition to affecting the oral and genital areas of the body, HSV can infect other areas. In this research experiment, Becket Feierbach and his associates looked to determine how HSV-1 develops spatial compartments within the host's nucleus where replication takes place.
The third research article I found dealt with a possible vaccine that is being developed to prevent being infected with HSV-2.
Feierbach B, Piccinotti S, Bisher M, Denk W, Enquist LW (2006) Alpha-Herpesvirus Infection Induces the Formation of Nuclear Actin Filaments . Megan Jones (left) and the author (right) had a chance to see how San-Diego-Zoo-born Yun Zi is doing. Littered throughout the airport are panda souvenir shops, mock habitats filled with plush giant pandas, and tourists decked out in panda garb.
Megan Jones, a SDZG veterinary pathologist, and I set off to China to teach a Giant Panda Pathology International Exchange training workshop in Dujiangyan.
The facility also contains a public education center filled with many creative and unique hands-on activities, including a real giant panda skeleton and—my favorite—a digital, interactive, panda necropsy table complete with an overhead surgical lamp!
The main focus of this workshop was developing necropsy, or post-mortem exam, skills through a series of lectures and hands-on wet labs.
So when Scott Tremor, the mammologist at SDNHM and a long-time friend of mine, called me in March to tell me about his latest adventure and make an interesting proposition, we were intrigued. This beautiful spot, part of Cabrillo National Monument, is closed to the public—the only way to reach it is down a cliff wall using a knotted rope. The goal of the day was to disarticulate the skull from the body and move it to the base of the cliff. These thin sections are then stained by different methods to allow microscopic evaluation of the cells in the tumor.
Since that time, we have received a lot of questions about how Gao Gao’s diagnosis was made and what the findings mean for his long-term prognosis. From this, the veterinary pathologists gathered clues from the arrangement and distribution of tumor cells, features of individual tumor cells, and the frequency of tumor cell division and invasion into adjacent normal tissues. All of this information was synthesized to determine the tumor cell type and if the tumor was completely removed.
In addition, there was no evidence in the surgically removed tissues of tumor spread beyond the testicle. The dark purple material at the center of the cell is the nucleus beginning to divide.So what does this mean for Gao Gao? In 1997, a seminoma was found in 26-year-old giant panda Hsing Hsing, from the National Zoo, and treated by surgical removal. These trees originate in the subtropical rain forest of eastern Australia but do well in frost-free climates such as ours. Using a dissecting scope with a camera attachment and a macro lens on a photo stand, we were able to capture the intertwined life cycles of the fig and the wasp.
Museums are not just filled with primary school students on field trips but with invaluable collections.
They need to understand each animal’s living requirements (food, water, space, territory, and reproductive strategies), but also anatomy and physiology. To make matters worse, they hide out in their burrows for extended periods of time and are mostly quiet.
Wildlife veterinarians, on the other hand, have to be much more clever and creative in using indirect measures of health. A desert tortoise with a prominent bony ridge on the top of its head is severely under condition, whereas one that cannot retract its head and limbs into its shell due to abundant subcutaneous fat stores is well over condition. It contains nerves, blood vessels, and bone and is sensitive to trauma as well as metabolic derangements.
Depending on the type and severity of the exudate, the tortoise may be suffering from an upper respiratory tract disease. Tortoises with yellow, casseous plaques on their tongue may be suffering from a viral or bacterial infection. Tortoises, as other reptiles, are ectotherms: they do not control their body temperature as consistently as mammals but rely on environmental sources to regulate internal heating and cooling. The Center temporarily houses almost 2,000 tortoises, and each individual has to have a health check at least once a year. We are now connected to a network of people on Facebook and Twitter with whom we tune in daily to see what our friends are up to. Who we are connected to in the virtual world and in real life influences different aspects of our own lives, such as whether we vote in elections, our happiness, our weight, and whether we catch the flu or acquire other diseases.
This is a challenging disease of birds, because whenever a case arises, we do not know how far an infection has spread through a group of “connected” birds sharing the same aviary.
Years of careful record keeping has created an archive of data documenting each bird’s aviary and enclosure-mates. These answers will allow us to develop better disease-management protocols to mitigate risk to birds at the San Diego Zoo and San Diego Zoo Safari Park, as well as in conservation programs around the world. The next time you are visiting the Zoo or Safari Park, remember that, even in death, animals are helping us learn about and conserve species around the world! Until one has actually observed or practiced in a zoo veterinary hospital, it is impossible to fully understand the amount of discipline needed and the challenges faced by veterinarians and support staff.
With more than 30 accredited veterinary schools in the United States, we have collectively hosted over 200 students from the US as well as Canada, Mexico, Brazil, Germany, France, Italy, India, Thailand, and China (just to name a few!). During and even after graduation, volunteering to participate in as many observational opportunities as possible enhances students’ ability to learn the many different aspects of the profession in the clinical setting. Most university career counseling offices have information regarding externships, and there are numerous externship opportunities listed on the American Association of Zoo Veterinarians website as well, including our facilities. This ensures they have enough experience and education to receive the greatest benefit while working in our practice. For those with sincere passion for conservation and caring for the Earth’s creatures, working as a zoo veterinarian is not just a living but truly a way of life. I can find dying cells, inflammation, various pathogens, scarring, thinning, thickening, bleeding, tumors, strange crystals, and unusual pigments. Since 2009, over 4,500 slides have been made of desert tortoise tissues, providing an invaluable resource for the understanding of disease in desert tortoises. On the left side of the picture, you can see normal nuclei: round or oval purple shapes that look very speckled, like chocolate chip cookies. Pueden localizarse en el cuero cabelludo, vertice de las axilas, mucosas de la boca y de las vias respiratorias superiores y en las conjuntivas. Las vesiculas, de base eritematosa se limitan a las zonas de la piel inervadas por los nervios sensitivos de uno o varis grupos contiguos de ganglios de las raices dorsales. En climas templados un 90% de la poblacion ha tenido varicela antes de los 15 anos de edad y un 95% antes de llegar a la edad adulta. El zoster tiene una menor tasa de transmision sin embargo los contactos que no hayan padecido la varicela al entrar en contacto con un herpes zoster enfermaran de varicela. Esto paso un dia lunes y el sabado estaba mucho mas extendida la mancha roja picaba,ardia y me dolia con el rose de la ropa y al acostarme a ese lado tambien , el sabado fui a medico y me dijo que era herpes zoster y me receto Aciclovir de 800 mg cada 12 horas tambien Findaler (Cetirizina diclorhidrato) de 10 mg 1 al dia y una crema Lisovyr (aciclovir) 5% 2 veces en el dia , tambien me dio Citodem 3 inyectable . MI MADRE DE 75 AÑOS TIENE APROXIMADAMENTE DOS MESES CON ESTE PADECIMIENTO ADEMAS DE SER DEABETICA E HIPERTENSA IMAGINARAN LO COMPLICADO DE SU ENFERMEDAD.
Tal vez yo vaya con mi bebita en otra movilidad, coordinaremos con el Dr porque recien veo que debe haber un tratamiento familiar dado nuestro caso que puede complicarse en la bebe y mi persona q nunca lo tuvimos. Several street corners in Dujiangyan are decorated with oversized giant panda statues arranged in various “panda-like” postures. Working with the recently built Dujiangyan Giant Panda Rescue and Disease Control and Prevention Base, which aims to rehabilitate sick and geriatric giant pandas and red pandas, we were tasked with teaching the first of a series of workshops intended to share knowledge and skills in wildlife disease surveillance, investigation, and research.
Necropsies are an essential tool for making accurate diagnoses and ultimately determining the cause of death, just like a human autopsy.
Thanks to the hard work of many experts in the field, including SDZG’s Wildlife Disease Laboratories Director, Dr. A 30-foot-long juvenile humpback whale had died, and the carcass had washed ashore at Pelican Point, on the tip of Point Loma. We timed our excursion to coincide with low tide, so we could access the beach and the whale. Naturally, the tide washing over the carcass had removed some of the flesh exposing some bone, but there was still a lot of work to be done.
Coast Guard airlifted it first to a nearby parking lot, then on to a spot where it was buried so local insects could finish cleaning the bones.
In this blog I’ll tell you about our analysis of the tumor in the Wildlife Disease Laboratories of the San Diego Zoo Institute for Conservation Research and what we know about the tumor in giant pandas and other animals.
In domestic animals, seminomas are common in older dogs, and they are usually completely cured by surgery.
The answer is that we can’t tell for certain if his tumor has been cured by surgery or if there is a small chance that it could reoccur at a later time. Hsing Hsing died two years later from kidney disease, and there was no evidence of any remaining tumor at his necropsy. These majestic trees can reach up to 200 feet (60 meters) with long, aerial roots providing the tree with additional support to hold up the immense canopy. The fig provides refuge and a food source for the wasps, and, in turn, the wasps pollinate the tree. Museum curators are not just librarians cataloging their specimens but scientists and researchers helping to save species. It is important to understand what makes an animal jump, fly, and live without water for long periods of time.
Though now extinct in North America, paleontologists at the museum are able to compare the local fossilized remains to the African hedgehog carcasses received from the San Diego Zoo.
Archiving and sharing tissue samples from them provide rare and extremely valuable resources for current disease investigations and future research.

Furthermore, they can pull their legs and head back into their shell as a safety precaution when startled, so all that remains visible are their shell and the armor-like aspects of their front and hind limb scales.
The goal is to release the tortoises into their native habitat, the Mojave Desert, to increase the wild population numbers. In the past hour, my friends on Facebook looked at the nutrition facts on a candy bar (Is that really a good idea?), posted a CUTE photo of a clouded leopard (thanks to my “friend,” San Diego Zoo Global), and humorously referenced her boss mistaking a Kanye West song for the ‘80s hit single “Ghostbusters.” This is my social network. Traditionally, disease acquisition has been attributed entirely to contact with other infected birds; however, recent studies conducted by the Wildlife Disease Laboratories, a division of the San Diego Zoo Institute for Conservation Research, show that the environment may also be playing an important role in the spread of this disease.
These data can be used in conjunction with health history to determine whether the occasional cases of avian mycobacteriosis we see are attributed to a bird’s social network or its environment history. The blue-chinned sapphire Chlorostilbon notatus is a species of hummingbird covered in shiny blue feathers—more a trick of the light than an actual feather pigment. My job as a pathology technician is to look for anything wrong outside and inside these animals. The pathologists let the nutritionists know, and they tested the nectar the sapphires were being fed—it, too, was low in vitamin A! The clinical veterinary medicine and veterinary pathology externship programs at the San Diego Zoo, San Diego Zoo Safari Park, and San Diego Zoo Institute for Conservation Research’s Wildlife Disease Laboratories provide just such an opportunity to a select group of students each year.
Working with such a diverse group of students also helps us, as we gain knowledge of veterinary practices in other countries.
Students should strive to observe different practice areas in veterinary medicine such as small animal, large animal, equine, zoo and exotic, pathology, research, or industrial. Each program listing contains specific information needed for applying to select institutions. Once students graduate and obtain their degree in veterinary medicine and a license to practice, many will apply for the University of California, Davis, Residency, which includes one year each at three different zoological institutions: Sacramento Zoo, San Diego Zoo, and San Diego Zoo Safari Park. It brings the staff of our veterinary services and pathology departments and San Diego Zoo Global as a whole great satisfaction knowing that the years of experience we share will be translated through the work of future generations of zoo veterinarians.
Well, it turns out that one of the best ways to figure out what health indicators most accurately indicate disease is to compare the information from the live tortoise to the changes we see in the tissues if the animal dies. Since November 2012, I’ve been describing the changes I see so that they can be correlated to what was found in the live animal. We are always on the lookout for bacteria or viruses that cause that most feared of tortoise infections: upper respiratory disease.
On the right side of the picture, the nuclei are bigger and have clumps of magenta in the center surrounded by a clear rim.
American Public Health Association, 2004   La varicela en nuestro pais tiene una presentacion endemoepidemica con ciclos epidemicos anuales. Las lesiones suelen aparecer en brotes sucesivos y se observan en diversas etapas de maduracion al mismo tiempo. Las lesiones, que son identicas a las de la varicela salvo que son unilaterales, pueden surgir en brotes irregulares siguiendo el trayecto de los nervios (dermatoma).
The city of Dujiangyan is in the Sichuan Province, just 45 miles from Chengdu, the country’s 7th largest city by population. The lab portion of the workshop enabled the participants to hone their necropsy skills using rabbits. Bruce Rideout, as well as the China Conservation and Research Centre for the Giant Panda, disease investigation will become an integral part of panda conservation, a necessity for any conservation plan. Humpback whales are relatively rare off San Diego’s coastline, so the museum wanted to preserve the specimen for its collection.
Andrew Cartocetti, Megan Varney, and Rachael Keeler) to put on their Tyvek® suits and boots and help out.
There, we were met by Southwest Fisheries Science Center employees, who are responsible for testing tissues and collecting measurements on all beached cetaceans. The soft, rubbery flesh was hard to cut through and the sand dulled our knives immediately.
However, in other species such as humans, a higher percentage of seminomas will metastasize (spread) to other organs without additional treatment such as chemotherapy. This is a common problem for pathologists who work with endangered animals, because very few tumors will ever be observed in these species, whereas it is easy to gather information on tumor behavior in dogs and humans where thousands of cases can be studied over time.
We have had an opportunity to compare the microscopic sections of Hsing Hsing’s tumor with the samples from Gao Gao, and they are very similar. And, if you have never seen inside a fig, with the fig wasps, it is a very incredible thing to look at!” We were curious, so agreed to help. Seth brought several figs ranging from green and firm to dark maroon with spots on the outside. As she is wandering through the fig, she spreads pollen from the fig she hatched in, thus helping the fig tree produce viable seeds. With the number of endangered species increasing, museums have evolved into a major resource for biologists and other researchers who study genetics, taxonomy, comparative anatomy, and even behavior. Many of these animals are not displayed anywhere else in the US, which makes the collection unique not only to visitors but to museums and researchers. However, only healthy animals can be released to increase their chance of survival and minimize the risk of spreading disease.
Here at the San Diego Zoo, I have been able to take an up-close look at this species, aptly named for its beautiful color. Since we often send and receive animals to and from zoos worldwide, this proves very beneficial throughout the animal shipment process. This demonstrates to selection committees that a student has researched the profession and holds a genuine interest in pursuing a career in the field of zoo and exotic animal medicine.
Most programs accept applications at least a year in advance, sometimes two, so it is important to begin identifying potential programs as a college freshman or sophomore. The residency program also partners with SeaWorld San Diego and offers residents an eight-week opportunity to work in aquatic veterinary medicine. The more we know about which tools work to predict severity and type of disease, the faster and more precise we are at identifying and helping animals at risk. This is more than just a head cold like people get and is a big factor in tortoise population decline.
Esta es la forma mas facil de identificar una varicela: en un determinado momento unas lesiones estan en forma maculopapular, otras en forma de vesiculas y otras en forma de costras.
A veces no sabemos y eso complica todo como en nuestro caso que esperamos no sea el inicio de algo peor en la familia sino el final. The Sichuan province is best known for their extremely spicy food, and one other thing, the giant panda! These skills include taking accurate measurements and photos, practicing proper tissue sampling techniques for histology and future testing, and ensuring all gross lesions are accurately described and recorded in the final report.
It had laid on the beach in the sun for over a month, and Scott was collecting volunteers to help clean the bones. With the warning that the carcass may have washed away overnight and may not be there when we arrived, we met up with other volunteers at the San Diego Natural History Museum and headed to the beach.
Tom was amazing at directing us the best way to maneuver the skull so we could cut away the muscles.
He explained the life cycle of the fig and the fig wasp as he cut them in half, and we set up the cameras.
They were soft and fleshy, with delicate flower structures and seeds lightly attached to the inner walls. After an extensive necropsy and investigation of an animal’s death, the body may be saved for a museum. Lily Cheng, another veterinary pathologist, volunteered to spend two whole months staring at a mountain of desert tortoise slides. Some savvy souls may note that no light microscope can show an individual virus particle (you really need an electron microscope for that, since viruses are smaller than the wavelength of visible light). In the end, the strength and endurance of so many people accomplished our goal; we separated and lifted the 300-pound skull to a safe place on nearby rocks.
What a great opportunity we had collaborating with our neighbors at the San Diego Natural History Museum to turn a tragedy into valuable learning experience.
Each mature fig contained several wingless male wasps, and Seth was lucky enough to find one female flighted wasp.
Evaluating these dynamics through time is where social network analysis is remarkably powerful. And this bird was not on exhibit—it was in my hand as I conducted an external postmortem (after death) exam. One of his areas of expertise and interest is in the evolutionary history of baleen whales, also known as the mysticetes. Ultimately, we hope to uncover the relative contribution of mycobacterial infections due to both the social network and the environment.
