Human body tends to get infected by various microorganisms that results in degrading their health standards.
Bacterial disease can be prevented by following medical measures and understanding major causes, which helps in preventing the infection significantly. There are various bacterial disease causes present in our day-to-day life, which has to be avoided for escaping from its infection. Harmful bacteria enters into an individual’s body through contaminated cuts, abrasions, rashes, infected insect bites and breaks available in the skin, tissues and other gums. The most common cause for bacterial disease is consumption of contaminated and harmful food by a person that creates a way of entry for microorganisms.
Kissing bacteria infected person and using needles of person for drug use and tattooing can cause bacteria to enter the body. It is important for people to keep checking their health condition, if there are any signs of defect, they have to contact general physician at the earliest for treatments. There are also chances of bacterial diseases caused though touching contaminated body fluids, feces and other excretes. Though, people take proper measures in eliminating the entry of bacteria, there are few accidents resulting in infection.

Mutations in the human genome may cause shifts in the gut bacteria of patients with inflammatory bowel disease. A new study by an international team of researchers shows for the first time that people may inherit some of the intestinal bacteria that cause Crohn's disease and ulcerative colitis, collectively know as inflammatory bowel disease (IBD). About 1.6 million Americans suffer from Crohn's disease or ulcerative colitis, according to the Crohn's and Colitis Foundation of America. Knights and his colleagues at the University of Minnesota worked with collaborators at Harvard, MIT, University of Toronto and University Medical Center Groningen in one of the largest international studies of its kind.
The results, which were replicated across two or more cohorts, showed that the human subjects' DNA was linked to the bacteria in their intestines. The intestinal community of bacteria is a complex system that is not only affected by genetics, but also by age, gender, medication and other factors. At least among mice, females have innate protection from certain digestive conditions, according to a new Michigan State University study. Scientists from the Institute of Food Research and the University of East Anglia have discovered how certain gut bacteria can protect themselves and others in the gut from antibiotics.
There is little evidence to support any consistent effect of probiotics on the gut microbiota of healthy individuals, according to a systematic review published in the open access journal Genome Medicine. A new study on the epigenetics of lactose intolerance may provide an approach to understanding schizophrenia and other complex, serious illnesses.
An international group of 253 scientists has conducted one of the largest genetic studies to date and identified 74 genetic variants that are associated with the years of formal education that an individual completes.
Many diseases, such as cancer, diabetes, and schizophrenia, tend to be passed down through families. Over the last several years, research teams across the world have scoured the genomes of cancer cells in a quest to uncover the genes that drive tumor growth.
In 2001, researchers developed a formula, or algorithm, that predicts whether a specific change in a gene sequence can result in harmful effects. There are still people running around claiming that these diseases are caused by MMR vaccine - as per the discredited Andrew Wakefield reports.
BACTERIA Bacteria are prokaryotic, unicellular microorganism that are found everywhere Bacteria are found in the soil, water and air – EVERYWHERE Bacteria are found on human skin and in the digestive tract Bacteria can enter other body systems and cause infections or disease. VIRUSES A Virus is a small particle that contains proteins and heredity material (DNA or RNA), but is not alive. NUTRITION If an organism is in good health it is more likely to fight off diseases and remain healthy. Unfortunately, this is not an excerpt from a science fiction novel, but rather a chapter from a bacteriology textbook.
In 1871, a Confederate army surgeon named Joseph Jones first described the disease during the Civil War. Throughout the 19th and 20th centuries, cases of NF occurred only sporadically and usually remained restricted to military hospitals during wartime, although some civilian population outbreaks have also occurred. Scientists are puzzled as to why the normally mild GAS bacteria can sometimes become deadly, as in the case of NF. The National Institute of Allergy and Infectious Diseases defines NF as "a serious but rare infection of the deeper layers of skin and fatty subcutaneous tissues (fascia)." Eventually, NF destroys not only muscle, but also fat and skin tissue. With further advances in medical research, "flesh eating disease" may be able to move from the pages of science fiction and bacteriology into the pages of ancient history. Bacteria that cause gum disease use a sophisticated, two-prong approach to selectively disarm immune cells.
In a new study, University of Pennsylvania researchers show that bacteria responsible for many cases of periodontitis cause this imbalance, known as dysbiosis, with a sophisticated, two-prong manipulation of the human immune system. Their findings, reported in the journal Cell Host & Microbe, lay out the mechanism, revealing that the periodontal bacterium Porphyromonas gingivalis acts on two molecular pathways to simultaneously block immune cells' killing ability while preserving the cells' ability to cause inflammation.
George Hajishengallis, a professor in the Penn School of Dental Medicine's Department of Microbiology, was the senior author on the paper, collaborating with co-senior author John Lambris, the Dr.


In this study, they wanted to more fully understand the molecules involved in the process by which P. The researchers focused on neutrophils, which shoulder the bulk of responsibility of responding to periodontal insults. Further experiments in mice and in cultured human neutrophils helped the researchers identify additional elements of how P. Inhibiting the activity of either PI3K or a molecule that acted upstream of PI3K called Mal restored the neutrophils' ability to clear P.
Not only does the team's discovery open up new targets for periodontitis treatment, it also suggests a bacterial strategy that could be at play in other diseases involving dysbiosis. Scientists say they have solved in mice the mystery of how an unusual bacterium can trigger the common dental condition periodontitis while residing in low numbers in the space between tooth and gum.
Scientists at Forsyth, along with a colleague from Northwestern University, have discovered that the protein, Transgultaminase 2 (TG2), is a key component in the process of gum disease. Patients with leukocyte adhesion deficiency, or LAD, suffer from frequent bacterial infections, including the severe gum disease known as periodontitis. Severe bacterial infections can push the human body into sepsis, a life-threatening cascade of inflammation and cell death that can be difficult to cure.
House dust mites, which are a major source of allergens in house dust, can cause asthma in adults and children. Follicular helper T cells (Tfh cells), a rare type of T cells, are indispensable for the maturation of antibody-producing B cells.
An effective vaccine against the virus that causes genital herpes has evaded researchers for decades. T cells, the security guards of the immune system, use a kind of mechanical "handshake" to test whether a cell they encounter is a friend or foe, a new study finds.
One among them that can be very dangerous is bacteria, which causes enormous troubles for people, when it creates infection. If a person is having sexual intercourse with an infected individual, he or she is highly prone to affected by harmful bacteria. These bacteria have the tendency to spread through ears, eyes and urethra, which helps in destroying immune system of a person completely. People having touched these bacteria carriers have contact with their mouth, ears, eyes and nose without washing their hands, which results in bacterial invasion into their body.
Infants, children, old aged people and individuals who have a medical condition that reduces their immunity levels can increase the chances for being affected by bacterial infection. People who do not have a habit of washing their hands frequently, especially after using the rest room, after touching pets, before eating, etc., are prone to bacterial infections more often than not. These bacteria will stop the immune system of the body, which allows the entry of not only bacteria, but also other foreign particles with ease.
The study, recently published in Genome Medicine, also confirmed that antibiotics could worsen the imbalance in the gut microbes. Understanding the causes of these diseases is another step toward prevention and treatment. The researchers examined three independent cohorts of a total of 474 adults with IBD who live in Boston, Mass. For example, this study confirmed that use of antibiotics is associated with a greater imbalance in the bacterial community in the intestines.
The medical name for this disease is necrotizing fasciitis (NF) and it is caused by a bacterium called Streptococcus pyogenes, or Group A streptococcus (GAS). The Centers for Disease Control and Prevention (CDC) reports that, worldwide, rates of NF increased from the mid-1980s to early 1990s. People often carry GAS in their throats or on their skin but exhibit no symptoms of illness. Invasive GAS infections may occur when the bacterium bypasses a person's normal defenses and enters the tissue through sores or openings in the skin. A minor trauma in an extremity, such as a small cut, bruise, or the chicken pox, becomes infected and is the most usual beginning to NF.
In fact, 10-15% of school age children may carry GAS in their throats and display no symptoms. Since many types of GAS exist, one of the challenges facing scientists is the development of one vaccine to combat all the different types.
The strategy prevents neutrophils from killing bacteria but still allows the cells to cause inflammation in the gums. In healthy people, these bacteria are typically harmless and often helpful, keeping disease-causing microbes at bay. The selective strategy protects "bystander" gum bacteria from immune system clearance, promoting dysbiosis and leading to the bone loss and inflammation that characterizes periodontitis. Ralph and Sallie Weaver Professor of Research Medicine in the Department of Pathology and Laboratory Medicine in Penn's Perelman School of Medicine.
Based on the findings of previous studies, they examined the role of two protein receptors: C5aR and Toll-like receptor-2, or TLR2.
There are large amount of bacteria available on human skin such as intestine and genitalia, which will cause major medical complications.


Moreover, bacteria have the characteristics of multiplying its count tremendously, it is necessary to stop its development at the earliest. This is an important step in developing drug treatments that target certain genes or certain products derived from the intestinal bacteria.
Previous studies have shown links between human gut bacteria and increased risk of a wide variety of diseases including diabetes, autism, heart disease, and even some forms of cancer. It was named "necrotizing fasciitis" in 1952, from necrosis, which means death of a portion of tissue, and fascia, which refers to the fibrous tissues that enclose and connect the muscles. Increases in the rate and severity of NF are associated with increases in the prevalence of toxin-producing strains of S. Some cases also occur after surgeries, including abdominal surgeries and cesarean deliveries, or after vaginal births. GAS spreads by direct contact with infected skin lesions or with nose or throat discharges from an infected person.
Researchers have now determined the genetic sequence for more than 95% of the GAS organisms in hopes of identifying the proteins causing virulence.
But, when disturbances knock these bacterial populations out of balance, illnesses can arise.
At the same time, breakdown products produced by inflammation provide essential nutrients that "feed" the dysbiotic microbial community. Blocking either of these receptors on human neutrophils in culture also significantly enhanced the cells' ability to kill the bacteria.
They found that the TLR2-C5aR crosstalk leads to degradation of the protein MyD88, which normally helps clear infection. Doctors and nurses in those locations collected samples of DNA from each human subject and the DNA of their intestinal bacteria over about a two-year period. Twenty-five percent of its victims die, and in severe cases, the patient is dead within 18 hours. Since a bacterium's generation time may be as short as 20 minutes, these organisms can evolve quickly. Normally, GAS is passed by close personal contact such as kissing and sharing eating utensils or cigarettes. Blood or pus cultures can be used to diagnose NF, and treatment includes intravenous antibiotics (penicillin and clindamycin) and aggressive surgical debridement (removal of infected tissue). The result is a vicious cycle in which inflammation and dysbiosis reinforce one another, exacerbating periodontitis.
In 1999, approximately 600 cases of NF were reported in the United States, according to the CDC. These infections are referred to as "non-invasive GAS disease." More than 10 million non-invasive GAS infections (mostly throat and skin infections) occur annually.
Many scientists believe that GAS has evolved to make proteins that cause the body's immune system to destroy the body's tissues directly.
Surgical intervention can range from removing flesh, subcutaneous tissue, and fat in early stages, to major limb amputation in advanced stages. Additionally, the CDC has also developed a new genotyping system for GAS isolates (emm typing) that improves strain identification. It is small wonder that the media has given the disease such a dramatic, horrible-sounding name. Sometimes GAS can travel to parts of the body where bacteria usually are not found (blood, muscles, or the lungs).
The combination of early diagnosis, antibiotics, and surgery is usually sufficient to save patients' lives. Both epidemiologists and improved surveillance of the disease will also help to identify trends and groups at risk. The resulting infections are referred to as "invasive GAS disease." One of the least common, but most severe forms of invasive GAS disease is NF. When subsequent necrosis (death) of subcutaneous tissue occurs, the tissue must be removed surgically.
The CDC warns that those with a higher risk of contacting the disease are people with chronic illnesses like cancer, diabetes, and kidney diseases requiring dialysis, and those who use medications such as steroids. The bacteria also causes the body to go into systemic shock, which may lead to renal failure, low blood pressure, respiratory failure, and heart failure. Breaks in the skin, such as cuts, surgical wounds, and chicken pox increase the chance of bacteria entering the body.
The foreign substance is called the antigen.An antigen can be a virus, bacteria, toxin or pieces of foreign substances.
