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.
They are divided into two different groups: yeasts and dermotophytes. Common parasite infection include scabies and head lice. Both of these will present with an itching of a particular area. With head lice you can see the actual parasite, whereas with scabies, the parasite is beneath the skin but will present itself with red track marks along an area where it has been. Both are highly contagious and it is recommended to avoid as much contact as possible until treated.
As the reliable water sources shrank and they were forced to drink the contaminated water. This may have also spread diseases throughout the Colony. The results being more deaths, because of the water sources being contaminated by filth from the colonists. [Doc.B] Shows that there was a large time of drought from 1606-1612.This likely affected the growth of crops. The result was deaths most likely caused by lack of food.
The critical symptoms are vasculature of the skin is inflamed, nerve damage and unconsciousness occurs, severe decrease in blood pressure, septic shock, high fever, high white blood count, respiratory failure, heart failure, and renal failure. The picture at the right is of the critical symptoms. There are several ways to prevent getting necrotizing fasciitis; they are always washing wounds and small openings with antibiotic substances. Also, cover the mouth when coughing and sneezing. Finally, avoid contact with people who show signs of sore throat.
about 500 to 1,500 happen in the us every year. this disease has two types; type I is caused by anaerobic bacteria with or without the presence aerobic bacteria, type II also called hemolytic streptococcal gangrene is caused by group A streptococci, other bacteria may or may not be present the disease may be also be called synergistic gangrene.Muscle and fat tissue are affected as a consequence of infection. Necrotizing fasciitis is a severe complication of group A streptococcal infection. The bacteria cause the destruction of skin and muscle by releasing toxins. Additional complications can occur from necrotizing fasciitis, such as shock and organ
Case Study Risk of Infectious and Communicable Diseases Cholera, a gastrointestinal infection caused by toxigenic bacterium, Vibrio cholerae serogroup O1 or O139, can cause acute, severe, watery diarrhea, dehydration, and death. Known risk factors for cholera outbreaks include lack of access to safe drinking water, contaminated food, inadequate sanitation, and large numbers of refugees or internally displaced persons. The 2010 cholera outbreak in Haiti following a severe earthquake and flooding underscored the vulnerability of populations due to poor sanitation, a strained public health infrastructure, and large numbers of displaced people. The earthquake in January 2010, damaged drinking water treatment facilities and piped water distribution systems throughout Haiti, and displaced an estimated 2.3 million people, the flooding that occurred later in the year exacerbated the problems. As of mid-November 2010, the Haitian Ministry of
A parasite is a tiny organism that lives in or on a host (A body) which they use in order to feed. Parasites can cause severe illness's, there are 3 main types of parasites: protozoa, helminths, and ectoparasites. 2. Bacteria salmonella(food poisioning) e.coli causes abdominal pain,cramps and diarreha Staphylococus found on skin Mrsa responsible for many infections. Viruses common cold,flu mumps and measles.
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.
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.
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.
