When MRSA infects skin, a swollen, red area develops, and it is usually painful. MRSA skin infections may develop pus or weep other fluids. If left untreated, a MRSA skin infection can go progressively deeper into the body, infecting blood and organs. Symptoms of MRSA infection can include chills, cough, chest pain, fever, fatigue, muscle aches, rashes, shortness of breath and a general feeling of malaise. The worst and final symptom of progressed MRSA infection is death Read more: http://www.foxnews.com/health/2012/05/08/mrsa-antibiotic-resistant-bug-that-has-health-officials-worried/#ixzz2UnSQcGzS When MRSA infects skin, a swollen, red area develops, and it is usually painful.
Giardia lamblia is a single celled organism that causes a diarrheal infection of the small intestines and is one of the most common parasites in the United States. Giardia lamblia is a flagellated protozoan parasite which means it is an organism with one or more whip-like organelles called flagella. Flagellum is a hair like appendage that protrudes from the cell body, and it is how the organism moves around. The infectious agent can be transmitted by ingesting or swallowing water, food, or soil that is contaminated with giardia cysts (hard shells containing giardia). Some examples would be public swimming pools or spas.
This can cause the person to have severe abdominal pain, fever, nausea and abnormal bowel habits. Rest, antibiotics and diet changes can treat mild cases of diverticulitis, but serious cases require surgery to remove the diseased portion of the colon. By including more high-fiber foods in your diet, it can help prevent both types of diverticular disease. Fortunately, most people with diverticulosis never develop diverticulitis. Causes Diverticula usually develop under pressure when naturally weak places in your colon give away.
Pertussis Angela Maina Anatomy and Physiology July 17, 2011 Pertussis Pertussis is a small bacterium that infects the upper respiratory tract by embedding itself in mucus (Allen, 267). It is diagnosed by performing a swab test of the posterior pharyngeal wall and identifying B. Pertussis on selective media. A fluorescent antibody test is also used (Satpathy, 56). It is a highly contagious airborne bacterial infection that causes violent rapid coughing and a loud “whooping” sound upon inhalation (Murkoff, 16). Pertussis is also known as “whooping cough” due to the “whooping” sound a person makes.
65-75% of small bowel obstructions are caused by adhesions (Royal Marsden 2011). Adhesions are loops of the intestine which adhere to scar tissue in the abdomen following abdominal surgery (Smeltzer 2010). When the small bowel becomes completely obstructed, the oral intake of fluid as well as saliva, gastric, biliary and pancreatic fluid accumulate above the obstruction (Royal Marsden 2011) the passage of all bowel contents also become impeded. This accumulation results in vomiting which in turn results in fluid loss and therefore an electrolyte imbalance, the secretion of sodium and potassium also increases (Doerr 2001). Peristalsis will initially continue, which as a result moves the contents of the intestine towards the obstruction; the peristalsis is what initially causes severe pain in the abdomen (Royal Marsden 2011).

Conditions like type 2 diabetes or AIDS are examples of this. Localised infection This is confined to one organ system or area in the body e.g. abscess or boil.
This gene codes for a protein that form an ion channel, facilitating the movement of salts (sodium and chloride ions) and water across the cell membrane. This is important in creating sweat, digestive juices and mucus [5]. In patients with cystic fibrosis, CFTR is prevented in carrying out these functions due to alteration of salt and water balance in lungs. This eventually causes dehydration in most of the organs and causes thick, sticky mucus to build up in the lungs and digestive tract. Consequently, this creates an environment that favours bacterial growth, and people who suffer from cystic fibrosis are exposed to rapid respiratory tract infections which lead to inflammation and progressive lung
Generally, a urinary tract infection, or UTI, takes hold when bacteria travel up the urethra to the bladder. If the bacteria ascend higher, a person may experience a kidney infection. The most frequent type of bacteria associated with UTIs is E. coli. Symptoms of a UTI include a frequent urge to urinate, burning pain in the pelvic area, or burning upon urination. Some people may feel pressure above the pubic bone.
This disease is a member of the herpes virus family and can lead to other infectious diseases such as “viral pneumonia, infection of the brain (encephalitis) and bleeding problems” according to the csg.org (2007). Early symptoms can range from a low grade fever, dizziness, fatigue, dehydration, and the worsening of asthma. This disease is most commonly exposed and passed among children, but can be even more dangerous if contracted by adults. It is noted that if you have had chicken pox, the shingle virus is embedded and lying dormant in your nervous system which can cause chronic pain syndrome at the site of the original shingles eruption also known as (post-herpetic neuralgia). Describe the disease, how it is transmitted, and the environmental factors that may make someone vulnerable to it.
It can be contracted through contact with animals or infected animal skin products (e.g. sheep skin, wool or cow hides, which are used for clothing or seat covers, drum skins, etc.) (DAFF, 2008), The bacteria can enter the body through any minor abrasion, where it will then fester and form a necrotic ulcer, a painless red ring of inflamed flesh with a black center known as “eschar”. If left untreated for long enough, the bacteria eventually works it’s way into the blood stream (Thompson, M. W., 2003), causing septicemia and death in 5-20% of sufferers (BHC, 2012). • Gastrointestinal (GI) anthrax, as its name suggests, occurs when the bacteria is ingested.
