Introduction (Overview)
The helicobacter pylori bacterium also commonly known as H. pylori is a spiral shaped bacterium that is often found growing in the digestive tract. H. pylori bacteria are found in more than half of the world’s population. The bacteria normally attack the lining of the stomach and the small intestines. Although they are present in many people the H. pylori bacteria is usually harmless. The bacteria are adapted to live and survive in the acidic environment of the digestive tract. Furthermore, H. pylori reduces the acidity of the environment around it to survive and will penetrate the lining of the stomach and small intestines where the mucus lining protects it from the body’s immune cells. H. pylori sometimes can interfere with the body’s immune response to ensure their survival and this causes stomach problems (Flemin & Alcamo, 2007).
The H. Pylori Infection, its Causes

pylori bacteria do not exhibit any symptoms. However, when the infection causes ulcers then the symptoms exhibited include abdominal pains which are most severe when the stomach is empty. Most patients describe it as a gnawing pain that is intermittent. This kind of pain can be relieved by taking antacid medication. It is advisable to see the doctor when such pain is continuous and severe. Treatment with antacid drugs will not cure the infection as they act only as a pain relievers. Other symptoms of H. pylori infection include nausea and vomiting, bad breath, lack of appetite, excessive burping and feeling bloated. However, these symptoms are also caused by several other conditions and could also be experienced by healthy people who are not infected with H. pylori. If these symptoms persist or if you notice a black color or/and blood in your feces or vomit it is important to seek further medical advice (Yamamoto, Friedman & Hoffman,
Making H. pylori a vital microorganism to research in order to expand the study of microbiology and its interaction with humans. According to Blaser, the H. pylori “is a group of extremely varied strains cooperating and competing with one another. They compete for nutrients, niches in the stomach and protection from stresses.” There can be a variety of strains found in a single stomach, and even though they appear identical, their genes are very different.
The stomach naturally produces acid, which is mainly responsible for food digestion and the destruction of any foreign pathogen or bacteria ingested with food. Acid is secreted by stimulating the partial
•Jose symptoms is derived from a disorder called Gastroesophageal reflux disease (GERD) occurring in the digestive system with the consumption of food, irritating the esophagus generally causing notable clinical symptoms such as the following: vomiting, chronic cough, angina, & regurgitation immediately after the consumed food. Jose's experience of the lump in his throat is caused by esophageal sphincter pressure.
E. coli are bacteria that can cause an infection in various parts of your body, including your intestines. E. coli bacteria normally live in the intestines of people and animals. Most types of E. coli do not cause infections, but some produce a poison (toxin) that can cause diarrhea. Depending on the toxin, this can cause mild or severe diarrhea.
The etiology of burning mouth syndrome is varied and often difficult to decipher clinically. The following factors have been cited as having possible etiologic significance:
49% of Chinese population aged 15 to 22 years are positive to H.pylori.(#108).more recent cross-sectional study in Chinese population shows prevalence rate of (43.8%) [Helicobacter. 2014 Dec;19(6):437-42. doi: 10.1111/hel.12153.

Legionnaires’ disease is an infectious disease caused most often by the bacteria Legionella pneumophila (L. pneumophila). The disease resembles severe pneumonia. Legionnaires’ disease is sometimes called “Legion Fever.” It was first discovered in 1976 when there was a pneumonia outbreak among people attending a convention of the American Legion in Philidelphia. In January of 1977 the bacteria was discovered as the causative agent of the outbreak. While outbreaks receive substantial media attention, thousands of people are exposed to the bacteria each year and never have any serious signs or symptoms of the disease. The elderly, immunocompromised and smokers are the most susceptible. Most outbreaks that do occur are in the summer when water temperatures naturally rise. Fatality rate of the disease ranges from 5 to 30 percent (The Mayo Clinic, 2008).
Every human has microbiomes that are personalized for the individual and are extremely important to maintaining a good health standing, however, these microbiomes can be capable of contracting a disease. One of the most common areas for these microbiomes to contract something that could be harmful to the person’s health is called the oral microbiomes, which are found in the mouths of humans. Within the biofilms of the oral cavity, rests these oral microbiomes that maintain a healthy equilibrium in the mouth. However, if not taken care of properly, oral microbiomes can be taken over by a pathogen that can quickly turn the state of the person’s mouth from a healthy equilibrium to a very unhealthy equilibrium (1). Some bacteria found in the oral cavity can be an extremely danger.
As you exit the bus, another passenger next to you starts to cough, and then you hold the handrail as you exit the bus. Since you’re late getting home, you take a shortcut through a field to get home quicker. These three simple acts just exposed you to bacteria, viruses, and insects that could cause illness or even death. Infectious diseases, also known as communicable disease, are spread by germs. Germs are living things that are found in the air, in the soil, and in water. You can be exposed to germs in many ways, including touching, eating, drinking or breathing something that contains a germ. Animal and insect bites can also spread germs.1
Some of the most common foods that cause symptoms like severe stomach pain, diarrhea, hives, swellings, wheezing, vomiting, hayfever symptoms, excema and wheezing are nuts, chocolate, strawberries, milk, wheat and corn. There is one term in particular that can be used to clear up some confusion about various kinds of reactions called food allergies. That term is called "food intolerance" and it applies to abnormal reactions to foods regardless of the cause.
Enterococcus faecalis is a genus of gram positive cocci and form short chains or are arranged in pairs. They are nonmotile, facultative anaerobic organisms and can survive in harsh conditions in nature. There are over 15 species of the Enterococcus genus but about 90% of clinical isolates are E. faecalis. E. faecalis is a nosocomial pathogen because it is commonly found in the hospital environment and can cause life-threatening infections in humans. It is a bacterium that normally inhabits the intestinal tract in humans and animals but when found in other body locations it can cause serious infections. The most common sites for E. faecalis infections are the heart, bloodstream, urinary tract, and skin wounds. Due to vancomycin-resistant Enterococci, many antibiotics have been shown ineffective in the treatment. In this paper, I will describe the ecology and pathology of E. faecalis; the antibacterial resistance; treatment; and, what you can do to prevent Enterococcus infection.
In some cases, even in the late stages, gingivitis may progress painlessly and slowly, creating little obvious signs. Blood while brushing your teeth, red, swollen, or tender gums, insistent bad breath or awful taste in the mouth, withdrawing gums, loose or moving teeth, and much more are some symptoms of gingivitis (“Gum Disease” n. pag.). Other symptoms of gingivitis are: bright r...
Microbes are microscopic life forms, usually too small to be seen by the naked eye. Although many microbes are single-celled, there are also numerous multi-cellular organisms. The human body has 10-100 trillion microbes living on it, making it one giant super-organism. Since the first link between microbes and diseases was made, people have been advised to wash their hands. Scientists, however, have recently started to investigate more closely how the microbes that call the human body home affect our health. While some microbes cause disease, others are more beneficial, working with our bodies in many subtle ways.
The overall purpose of this experiment was to estimate the prevalence of Helicobacter pylori, which is formerly called Campylobacter pylori, infection and histologic gastritis in asymptomatic individuals. It was done by using endoscopic biopsy of the gastric antrum and corpus.
Let's take a look at a few of these things, and make sense of it. If you are having viral gastroenteritis, this is an inflammation that occurs both in the stomach and in the intestines. Viral gastroenteritis in very simple terms, is simply the flu. The flu however, can wreak havoc on the body, and cause many symptoms to occur, one them being severe degrees of diarrhea,and the other weight loss due to that. Other symptoms are vomiting, having stomach pain and cramps, fever, chills alternating with sweating, and joint stiffness.
