Necrotizing Fascitis Kayla Duke 4th hour anatomy Necrotizing fascists is a rare disease where the bacteria destroys tissue under the skin. The tissue death, called necrosis or gangrene spreads fatly. this disease could cause death in 12-14 hours. Some drugs used for treatment are antibiotics like penicillin, or aminoglycoside. or third generation cephalosporin.
Author: Jake Date: 12/09/2010 Introduction This essay includes my findings from research on the disease, and explains the signs, symptoms, causes, cures and prevention of the pathogen Cholera. The Bacterium Cholera is a severe bacterial infection caused by the bacterium “Vibrio cholerae”, the most common symptoms of the infection are diarrhoea ,vomiting and muscle cramps, this can lead to rapid dehydration and sometimes death. You can transmit Cholera by water that is contaminated with infected faeces; and also transmit it due to poor food hygiene1. Cholera kills an estimated 120,000 people a year2. 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.
CU254 Causes and spread of infection. 1.1/2 Bacteria There are 3 types of Bacteria cocci, bacilli or vibrio, and spirilla or spirochetes. Bacteria is found in everything the only place they aren’t found is where humans have sterilised. They can cause illnesses like tuberculosis, tonsillitis, and laryngitis and food poisoning Virus Virus is a toxin or poison. It is a microscopic organism consisting of genetic material.
Some fungi have beneficial uses. For example, penicillin and yeast for baking. Thrush is a common fungal infection. Parasites are small organisms which depend can only live on a host. Plants, animals, humans, fish, birds and reptiles can all be host to parasites.
coli 0157:H7 Facts • E. coli 0157:H7 is a gram-negative bacterium that can produce a bloody diarrhea due to toxins it secretes when it infects human intestinal tracts. • The symptoms of E. coli 0157:H7 infection may include a low fever, nausea, vomiting, stomach cramps, and bloody diarrhea. • E. coli 0157:H7 is notorious because it can cause additional complications in children and the elderly; renal failure, anemia, and dehydration especially for children (termed HUS or Hemolytic-uremic syndrome) and spontaneous bleeding, organ failures, and mental changes in the elderly (termed TTP or thrombotic thrombocytopenic purpura). Some of these patients develop disabilities or die. • Diagnosis is definitively made when E. coli 0157:H7 is isolated, usually from the patient's stool, and identified as serotype 0157 by immunologic tests.
Identify the differences between bacteria, viruses, fungi and parasites Answer: Bacteria Bacteria are single-cell microorganisms which generally exist in large numbers and are microscopic in size. Bacteria can be either beneficial (bacteria in the intestinal tract aid digestion and are part of the normal body flora) or can be the cause of disease (for example pneumonia, food poisoning or bacterial meningitis). Viruses A virus is an infectious agent which can only live and replicate inside organism cells. The main difference between viruses and bacteria is that they are unable to reproduce in food – they need a living host cell to replicate. They replicate by infecting and taking over the functions of the host cell.
Compare the beneficial and detrimental effects of Escherichia coli on humans. many bacteria are essential in our body to help it finction proberly. Some of these bacteria help digest food and fight off sickness, however certain bacteria invade the bpdy and attack causing infections. Escherichia coli is an evolving cause of foodborne illness. An estimated 73,000 cases of infection and 61 deaths occur in the United States each year.
E-Coli 0157 Escherichia coli (E. coli) are gram-negative bacteria that can survive in an environment in the absence or in the presence of atmospheric oxygen (Facultative anaerobes) and, depending on the environment, may or may not produce thin hair-like structures (flagella or pili) that allow the bacteria to move and to attach to human cells. The bacteria commonly habitat in human and animal gastrointestinal tract, water,….. The cell shape is spherical, spiral and plate – rod –shaped ; unicellular and multicellular forms in filaments or aggregates. Oval straight or curved rods, and helical. Reproduction is by binary fission or some groups reproduce by Budding.
USA vaccines cover A, C, W-135, and Y but not B (Coffee, 2015). The incubation period of meningococcal disease ranges from 2 to 10 days. The disease is spread through saliva and respiratory droplets. The most common way people transfer the disease is through kissing, sharing drinks, sharing used silverware, sharing lip balm, and close contact with an infected person who may cough or sneeze within three feet of an individual. Meningococcal meningitis is a fast moving, deadly infection that kills 10 to 13% of its victims within a matter of hours or days (CDC, 2015).
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
