825,826) B. If Zachary has a peptic ulcer affecting his stomach or duodenum, which components of the peritoneum will be affected? If the ulcer eats a hole into the wall of the stomach, bacteria and partially digested food can spill through the opening into the peritoneum causing severe inflammation of the abdominopelvic cavity and the visceral peritoneum, which covers some other organs. (Jenkins & Tortora pg. 826) C. How can Zach’s stomach contribute to the formation of ulcers in other parts of the G.I.
It begins at the site of a break in the skin (a surgical or non-surgical wound). In order for someone to contract necrotizing fasciitis, the bacteria must be introduced into the body. Group A Strep is the same bacterium that causes strep throat This group of bacteria is responsible for mild cases of sore throat (pharyngitis), skin infections, as well as rare, severe illnesses such as toxic shock syndrome and necrotizing fasciitis. However, there are various strains of the bacteria, some of which are more powerful than others. With the right set of conditions, necrotizing fasciitis is a real risk and can cause severe damage.
In the meantime they rob your system of nutrition, loading you down with their excretions and secretions these include Lice and Ringworm 1.3 Colonisation is when a bacterial strain invades a region of your body and starts to rapidly divide - it sets up a new colony Infection is similar but only usually used for opportunistic pathogenic bacteria - that is it does not usually refer to bacteria that normally inhabit us 1.4 Localised infection is restricted to a ceratin region of your body Systemic infection means that the infection is throughout your body. This usually means that the bacteria have been able to invade either your ciculatory system or the lymphatic system and spread 1.5 Some of the poor practises that may
If the bacteria enter the small intestine, they use their flagella to propel themselves through the lining of the intestinal wall, they produce a toxic protein. One part binds to specific carbohydrate receptors on cell-surface membrane; the toxic part enters the epithelial cells. This causes ion channels to open and Chloride ions flood into the lumen of intestine. Water then follows them into the lumen which causes watery faeces (diarrhoea) and dehydration4. Because of the improvements in sanitation and hygiene in the last 100 years, Cholera has been wiped out of England and much of the rest of the world3.
The most popular theory is that the body’s immune system reacts abnormally in people with Crohn’s disease, mistaking bacteria, foods, and other substances for being foreign (www.gicare.com). The immune system’s response is to attack the invaders. During this process, white blood cells accumulate in the lining of the intestines, producing chronic inflammation, which leads to ulcerations and bowel injury. Scientists do not know if the abnormality in the functioning of the immune system in people with Crohn’s disease is cause, or a result, of the disease (www.gicare.com). Researches have shown that the inflammation seen in the GI tract of people with Crohn’s disease involves several factors such as genes the patient has inherited, immune system and environmental factors
It can be caused by raw meat coming in contact with already prepared food or unwashed food, and undercooked food. The main cause of salmonella is coming in contact with feces from a person or animal. As gross as this sounds it does happen due to people not washing their hands, thus causing salmonella to enter the body and go into the intestines and that is where it lives until killed. It is a very small bacteria that cannot be seen by the human eye just by microscope. Salmonella is very serious when it is contacted and can be deadly, so make sure you follow proper hygiene to ensure that you are getting any bacteria off of your food and hands.
Crohn’s Disease Anatomy & Physiology Ashley Goodnight Crohn’s Disease Anatomy & Physiology Ashley Goodnight Abstract I am writing my paper on Crohn’s disease. In this paper you will find information on this disease and how people are affected. I will be explaining sign and symptoms, who may be at risk, and treatment options. Crohn’s disease is a chronic disorder of the digestive system. Crohn’s disease can affect any area of the gastrointestinal system from the mouth to the anus.
If left untreated the symptoms could worsen and you could be left with septicemia, food poisoning like symptoms, bleeding from under the skin, in the urine, from the mouth and nose, shock, kidney failure, breathing problems. Considering the plague is so rare it is easy to be dismissed as something else but if it is suspected, you would need blood work to confirm this diagnosis (Yersinia pestis, 2012).. Simple tests can give significant insight into the types and levels of pathogenic tendencies the bacteria at hand may have. Tests for the general structure of the bacteria include Gram staining in which the shape, outer membrane structure, and presence of spores can be determined. A hanging drop test determines whether a bacterium has one or more flagellum.
Common symptoms are acral necrosis of the extremities (such as the toes, fingers, lips and tip of the nose), high fever, nausea, vomiting, and breathing difficulty. Left untreated, Yersinia pestis can multiply rapidly in the bloodstream, possibly causing septicemic plague or even creep towards the lungs causing pneumonic plague. In order to diagnose bubonic plague, testing in the laboratory is required. Identification of the bacterium Yersinia pestis culture in a sample of serum from a patient’s blood is used for confirmation of the
Abdominal pain and abdominal cramping is caused the inflammation of the walls and eventually thickens the walls with scar tissue and leads to cramping. Mild Crohn’s causes moderate intestinal discomfort and in more severe cases, can cause nausea and vomiting. Blood in the stool is caused by food being moved from the digestive tract through the inflamed tissue. The bleeding might be notices as bright red directly in the toilet or darker red blood that is mixed into the stool. Crohn’s also causes small sores or ulcers on the surface of the intestines that eventually penetrate into the intestinal walls.
