The initial steps in the evaluation and management of a patient with infection are similar to those taken when treating all emergencies.
To determine the etiology of a patient’s infection, a careful history and physical examination must be obtained. Further clues, including onset, progression of symptoms, and associated events, may help differentiate between etiologic agents. The patient’s past medical history can be critical in defining which organisms are more likely to be causing the infection. Another factor to consider is where the infection was acquired, because hospital-acquired organisms tend to be more resistant to antibiotics than those coming from the community. Physical ExaminationThe physical exam may give valuable diagnostic information, especially regarding the site of infection, which, as previously mentioned, is one of the most important hints as to the possible etiologic agent. Pulse oximetry, long regarded as the “fifth vital sign,” has the appeal of an objective and inexpensive way to assess breathing and oxygenation.
When evaluating a patient, the physician must pay close attention to the patient’s mental status. The chemistry panel can occasionally offer clues to the etiology of an infection, as in the case of an elderly patient with cough, fever, hyponatremia, and elevated liver function tests (LFTs), possibly indicating Legionella pneumonia. Though an elevated WBC is associated with infection, its predictive value for bacterial disease has proven to be low.27,28 Serious bacterial illnesses may present with a normal WBC count, and WBC count elevations are often due to causes other than bacteria, such as viral infections.
When managing patients with respiratory infections, a physician must decide whether to obtain a pulse oximetry measurement alone or to draw an arterial blood gas. A urinalysis is not necessary to diagnose a UTI in women ages 18-65 who present with symptoms of UTI, such as dysuria, frequency, and urgency, and who have no complicating factors.38 Complicating factors include diabetes, pregnancy, mmunosupression, underlying urinary tract disease or renal calculi, recent medical intervention (hospitalization or catheterization), recurrent UTIs, or failure of therapy. Urinary dipstick testing has replaced urinalysis in many centers, because of its low cost, speed, and convenience.
The cerebral spinal fluid (CSF) should be evaluated for cell count, glucose, protein, culture, and Gram stain on all patients. The acute phase reactants are proteins produced by hepatocytes and other cell types in response to infection, inflammation, and tissue injury. Another acute phase reactant that is currently under investigation is serum procalcitonin (PCT). When performing radiologic studies in the ED, the physician must judiciously choose the modality that offers the highest yield.
In a few instances, the Gram stain can be useful, mainly to identify bacteria in those body fluids that are normally sterile.8 In the ED setting, that usually means either the CSF, urine, or abscesses. Sputum Gram staining in community-acquired pneumonia is generally not useful and not recommended.
There is some controversy around when to prescribe antibiotics for pharyngitis, as well as when to obtain throat cultures or rapid strep antigen detection testing (RADT). The identity of an infectious organism usually cannot be known with certainty in the ED, as culture results take days to come back.

This is a great resource for answers, help, & advice to aquarium and pond questions not found elsewhere; With regular posts & article updates. In our research; we use aquaculture, horticulture, medical, & university research to compile many of our articles. This applies to most ALL fish (from cichlids to arowanas), but since I get so many emails and questions pertaining to Betta Fish, this is the main subject of this article. Let me first start out by noting that "Fin Rot" is a generic term that does not define any one disease, rather there are many causes of this Symptom; of which Fin Rot is better described as a symptom with more than one cause. As well opportunistic bacteria such as Columnaris, Pseudomonas, or occasionally Aeromonas can result in fin rot (often taking advantage of fish weakened by other causes). See a picture further into this article for a picture of a Betta with Columnaris induced fin rot. Finally, especially as per Bettas, genetics and age can lower a fish resistance to disease. Unfortunately the popularity of bettas (& other fish) has led to the in-breeding of Bettas that has resulted in genetically weak fish. The end result is a Betta that is predisposed to diseases, including fin rot, and even treatments that may work under normal circumstances will not with these fish. I cannot emphasize how often I have traced back cases of Betta Fin Rot (of of more than one bacterial pathogens) to ammonia levels that are constantly in flux!
Personally I recommend a small Sponge Filter (such as the Hydro Sponge Mini)if at all possible for a healthy bio filter. These parameters, along with a low ammonia & nitrites are important for controlling many fish diseases, not just fin rot.
Often in emails, forums, and my previous aquarium maintenance "Fish Doctor" house calls, I have found that Betta keepers (& other fish too) tend to worry about pH and use products attempting to "nail down" "hard" ph numbers while ignoring KH and positive mineral ions. The KH; which are alkaline buffers plus acid buffers are more essential than a specific pH (within reason as obviously a pH of 5 or 9 is not acceptable). These buffers maintain a stable pH and just as importantly carbonate hardness (KH) maintains a healthy nitrogen cycle as without these carbonate buffers your nitrifying bacteria cannot thrive and you end up with even more dangerous ammonia spikes! The second part of Aquarium Chemistry (GH, KH, pH) that is also important (if not more so) and also missed by many is the need for positive mineral ions (electrolytes) in the water for a healthy Betta (or other fish) immune system.
Often Betta Keepers will use RO, Drinking, or Distilled Water without adding back these ESSENTIAL elements.
Even when tap water is used, often products such as "pH down" or "7.0" are employed, which when used alone can drive out some essential mineral ions. The use of too much incorrectly treated RO water can result in Redox stress, although the flip side is attempting to make up for neglect in adding positive mineral ions too quickly which also can add stress (both are similar to rapid pH changes). Another chemistry stressor is oxidative stress from un-treated tap water or too high of a Redox reading (constantly over 300mV).
Any of these before mentioned Redox can lead to a Columnaris infection that can then lead to a case of Columnaris induced fin rot (which is often a much more difficult to treat fin rot when compared to a minor cases of simply ragged fins). Best is a balanced approach which includes actually maintaining GH (of over 100 ppm) if only to maintain these essential mineral ions (cations) which are depleted quickly even though your GH test kit shows a higher GH.


Using products such as driftwood fragments, Peat, Pillow Moss (AKA Frog Moss) or Atisons Spa for their Indian Almonds leaves to naturally provide a tannin acid buffer along with Alkaline Buffers such as SeaChem Alkaline Buffer is a must for use with RO water and even some tap waters.
These mineral blocks come in sizes small enough for a fish bowl and can be used with Pillow Moss or even driftwood fragments to act as an acid buffer. Pillow Moss can be placed in aquarium filter bags (such as by Lees) to prevent it from coming apart if used directly in the aquarium. However, sometimes with large fish, there is little you can do as the constraints of an aquarium can lead to a large fish simply injuring itself on the glass. The picture below shows an Arowana with fin rot most likely caused from constant contact with the glass. One of the first actual treatments I would consider is a Medicated Fish bath that includes salt (Sodium Chloride), Methylene Blue, and for moderate to serious fin rot issues, a mix of antibiotics Nitrofurazon and Kanamycin.
The methylene blue is very helpful for fin rot and ulcerations caused by ammonia or nitrite poisoning. However Methylene Blue is not as a strong an antibacterial for gram negative bacteria, if these baths are ineffective, I would switch to Potassium Permanganate (which is a stronger oxidizer). Also be careful about over dosing with Potassium Permanganate as it is a strong oxidizer where you are essentially oxidizing the "fin rot" more than the fish! Potassium Permanganate (diluted approximately 50% to 60%) or Hydrogen Peroxide can also be used as a "swab" on damaged fins or other areas of infection. Next, assuming your Betta or other fish (such as an Oscar or Arowana) actually has a bacterial infection you may have to start an in tank treatment.
Pseudomonas bacterium may be the cause of mild fin rot infections in which the fish generally only display frayed fins and black fin edges. A strong "in tank" treatment would be the before mentioned (for fish baths) Nitrofurazone and Kanamycin combination. As well Triple Sulfa is generally less harsh on the fish and is a good choice for generally less difficult cases of fin rot with Pseudomonas as the bacterial cause.
If this is a serious infection, most often these are caused by gram negative bacteria and treatment with primarily gram positive antibiotics such as Tetracycline or even Maracyn 2 (to a slightly lessor extent) will often be futile as the vast majority of aquarium bacterial infections are gram negative. Columnaris, Pseudomonas, & Aeromonas are ALL Gram negative so if someone suggests a gram positive treatment for your fish' fin rot, it is not going to be effective (unless your fish has much less common gram positive infection)!! Melafix or better, Triple Sulfa can be an excellent first aid after a minor fin injury such as damaging a fin on a rock or even the glass in the case of large fish such as Arowanas. A Medicated Wonder Shell, while not a specific fin rot remedy, it still has medications that are good at addressing common secondary infections such as Saprolegnia, and just as importantly, a Medicated Wonder Shell helps with mineral Cations which in turn helps the fish in its own natural defenses in healing from a minor injury.
When used with Triple Sulfa, a Medicated Wonder Shell becomes an excellent treatment of for fin rot caused by an injury, especially injuries that are the result of collisions with sharp objects or simply the side of the aquarium in the case of large fish. Even suggested steps such as the use of a Level 1 UV Sterilizer should be considered if at all possible, although usually not practical for the average Betta owner. However with larger Betta Breeders or similar multi Betta specimen tanks with dividers, the use of a UV Sterilizer may be practical. Make sure is you are able to employ a UV Sterilizer that you change your UV bulb every six months for optimum efficiency.
Clear Betta Spa contains wild almond leaf extract to simulate the natural environment of the native soft water fish. Other natural botanicals, including Yucca extract, help control ammonia, reduce stress and maintain cleaner water.

The basics come first: intubate sick, hypoxemic, and septic patients, if needed, and provideoxygen and circulatory support when indicated. Bacteriologic statistics help identify the organism most likely to cause infection in a given patient at a given site (“specific organisms like specific sites”).
For example, a patient with pneumonia who recently had a seizure disorder may have aspirated elevating anaerobes on the list of suspects.
Asplenic patients, or “functionally asplenic” patients, like those with sickle cell disease, would be prone to infection with encapsulated organisms.
It is important to know the patterns of resistance for both hospital- and community-acquired organisms in your area. For example, a child with a bullous skin lesion probably has infection, while a young, healthy woman with costovertebral angle tenderness probably has pyelonephritis.
The standard first goal of emergency medicine is an aggressive approach to correct abnormal vitals. The tympanic thermometer has been shown to be poorly sensitive for fever compared to the rectal. As long as its limitations are kept in mind (ie, its dependence on tissue perfusion, ambient temperature, skin color, presence of nail polish), it is an excellent tool that gives more information than respiratory rate alone. Additionally, the chemistry panel may show the hydration status, renal function, and acid-base status of the patient.
Obtaining a WBC may be helpful when following a known abnormality or looking for an expected effect, such as drug-induced leukopenia.
As previously mentioned, the pulse oximeter has often been labeled the “fifth vital sign,” since it can give a good estimation of a patient’s respiratory status. However, if the physician prefers to evaluate uncomplicated patients via urinalysis, a urine culture is not warranted. Although the finding of pyuria on urinalysis is very sensitive (95.8% sensitivity), it is not very specific (71%).
More specific studies, such as viral cultures, VDRL, and cryptococcal antigen should be obtained, if clinically indicated.45 Currently, many physicians order a head CT in patients with suspected meningitis before proceeding to an LP, in order to screen for any intracranial abnormalities that may lead to brain herniation secondary to removing CSF.
These reactants are quite nonspecific and nonsensitive for identifying individual disease entities.
This aminopeptide is identical to the precursor of calcitonin, but it has no hormonal activity. For example, Waters view x-rays to diagnose sinusitis are only 68% sensitive and 87% specific for maxillary sinusitis.


In 2002, the Infectious Diseases Society of America (IDSA) developed a practice guideline for the diagnosis and management of group A streptococcal pharyngitis.60 They recommend that, if the clinical suspicion for strep throat is low — based on the absence of fever, anterior cervical adenopathy, and palatal petechiae — symptomatic treatment is all that is required. Blood cultures should be performed in patients who are immunosuppressed (eg, HIV, malignancies), have sickle cell disease, are steroid-dependent, or are admitted from a nursing home.
As well often these same less-than-scrupulous breeders will dump older Bettas on the market after their useful breeding life has passed, so a Betta you purchase may not only be genetically weak, but much older than you think! With fish such as Arowanas, sometimes a bare bottom tank can prevent the fish from injuring their fins as they might dive to the bottom for food sources. Again, this is ESPECIALLY common with Arowanas where many cannot even turn around in the width of the aquarium often used to house them. The most common bacterial causes of fin rot being Columnaris & to a lesser extent Aeromonas Bacterium.
However, do not use this product if fish have large wounds or are suffering from septicemia, since Trimethoprim can lower blood platelets. In such a host, Haemophilus influenzae and pneumococcus can cause overwhelming sepsis in a very short time. Occasionally, there will be special physical findings that point to a specific etiology, as for example the erythema migrans rash characteristic of Lyme disease. One study followed 171 elderly patients admitted to a hospital with a presenting diagnosis of delirium and found that the most common cause of delirium was infection (34%), particularly pneumonia and urinary tract infections.26 For more details pertaining to the physical exam, please consult Table 6. Both a urinalysis and a urine culture are recommended in patients with complicating factors, and in patients with pyelonephritis.39 Children diagnosed with UTI may initially have a negative urinalysis but positive urine cultures. The presence of bacteria on microscopic examination is less sensitive (40-70%), but is more specific (85-95%). C-reactive protein (CRP) concentrations “increase with acute invasive infections, which parallel the severity of the inflammation or tissue injury.”51 However, the CRP is an expensive test that may not be available at all institutions. PCT is usually found in the thyroid gland only, but during bacterial infection it is found in serum.53 One study has shown that procalcitonin levels are significantly increased in cases of severe bacterial infection and sepsis,54 while viral infections and localized inflammatory responses present with low levels.
Symptoms such as coryza, absence of fever, diarrhea, and conjunctivitis point to a viral etiology. Obviously, blood cultures should be drawn in patients who may be septic or may have infective endocarditis or bacterial meningitis. This is especially common of Bettas sold to discounters such as Walmart and chain pet stores.
The alveoli are the areas where gases are exchanged between the air in the lungs and the blood. Even though a thorough history usually leads to a correct diagnosis, it can at times be misleading. Though the clinical presentation can be useful, it might sometimes be atypical or even misleading, especially in the very young, the elderly, and the immunosuppressed. Together with central venous pressure, it should be one of the most closely monitored parameters in patients presenting to the ED in early sepsis.
On the other hand, relative bradycardia in a hypotensive or febrile patient can sometimes give a clue to the specific etiology of an infection (eg, salmonella sepsis). Although arterial blood gas measurements cannot discriminate between viral and bacterial infections, they may aid in the detection of hypoxemia in patients with community-acquired pneumonia. However, the presence of positive leukocyte esterase and nitrate has a much higher correlation of culture-proven UTI.41 Those UTIs caused by gram-positive organisms will not be nitratepositive. Following these recommendations would significantly reduce the number of unnecessary head CTs currently ordered. Currently, the only disease entities studied in the context of evaluating CRP and ESR utility in the ED setting are pelvic inflammatory disease (PID), appendicitis, and septic arthritis. If there is suspicion for group A strep, either a throat culture or rapid antigen detection test can be performed.
Bacteria like these ause lower respiratory tract infection (LRTI), which is known as bacterial pneumonia.
It is of utmost importance to start antibiotics as soon as possible, as this may be a lifesaving action. Your hospital laboratory will often be able to provide you with the sensitivities of the most common organisms. One study evaluated 1009 febrile infants for sepsis and found that the sensitivity of the absolute band count was significantly superior to the total WBC in predicting outcome.34 Another study looked at the absolute band count in infants = 60 days of age with fever (rectal temperature = 38? C) who were at low risk for serious bacterial infection according to the Rochester criteria. In a prospective cohort study of 2267 patients, hypoxemia was most associated in patients older than 30 years who had chronic obstructive pulmonary disease (COPD), respiratory rate greater than 24, altered mental status, and involvement of greater than one lobe on chest x-ray.
Once there is a clinical suspicion for meningitis, blood cultures and an LP must be performed immediately, and antibiotic therapy should be started without delay to help prevent adverse outcomes. However, in low-risk patients with a low ESR, one may choose to observe the patient closely. One study of patients admitted to an ED in China found that PCT is no better marker for infection than CRP.55 Further study of this reactant is clearly warranted is identical to the precursor of calcitonin, but it has no hormonal activity. However, many RADTs are significantly less sensitive than the throat culture; therefore, the IDSA recommends follow-up of a negative RADT with a throat culture in adolescents and children. Pneumonia can also be caused by viruses, fungi, parasites, and chemical or physical injury to the lungs. They found that the absolute band count varied widely from laboratory to laboratory.35 The recommendation is that, if the absolute band count is to be relied upon, then the physician should be aware of the laboratory’s definition of segmented neutrophils, since this varies so greatly.
Blood cultures should be drawn before antibiotics are begun, since 47-77% of patients with bacterial meningitis have positive growth on blood cultures.47-49 Once antibiotics are given, an LP should be performed as soon as possible since CSF sterilization can occur rapidly. In short, the ESR has a low utility in the ED, but it may be used to distinguish high-risk from low-risk patients.
Testing should be conducted in children who have had contact with individuals with confirmed strep throat in the prior 2 weeks. One retrospective study examined the rate at which parenteral antibiotic petreatment in a pediatric population sterilizes CSF cultures and found that there was complete sterilization of meningococcus (Neisseria meningitidis) within 2 hours and the beginning of sterilization of pneumococcus by 4 hours of therapy.50 An adequate culture can help guide antibiotic therapy and may also rule out bacterial meningitis.
Children should not be treated for group A streptococcal pharyngitis in the absence of a positive test.
