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.
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.
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
Complications of the disease include encephalitis, blindness and pneumonia. Pregnant women are at high risk for miscarriage or preterm birth. (CDC) Those highest at risk for the infection are unvaccinated young children, unvaccinated pregnant woman and individuals who are non-immune to the disease. In the year 2011, 158,000 deaths around the world were caused by the measles, mostly children under the age of five. (WHO) Every year it is
Running head: Giardia Giardia Carla Linder University of Phoenix Abstract In the follow document you will learn how to identify the causes, view a list of the symptoms, and observe the treatment, diagnosis, and prevention associated with the parasite giardia also known as amoeba parasites. Giardiasis is the most frequently diagnosed intestinal parasitic disease in the United States. Giardia lamblia is a protozoa (an amoebic parasite) and it lives in the water, food, and soil. Giardia or amoeba parasites The infectious agent or pathogen that causes this infectious disease is a microscopic parasite called Giardia lamblia. 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.
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).
The virus can be contracted when people breathe the contaminated air or touch a contaminated surface and proceed to touch their eyes, nose, or mouth. The measles virus can live in the air or on a surface up to two hours after exposure of the virus. Many high risk factors come with an unvaccinated person being exposed to the virus. It has been proven that ninety percent of unvaccinated people whom come in contact with the measles will become ill with the virus. Travelers whom travel to countries that have an increased risk of measles outbreak need to protect themselves by getting vaccinated before traveling, this could help to prevent bringing the illness back home with them.
About 42 percent of the amount of Agent Orange that we used was devoted to crop destruction; the products of hours of hard work were demolished within seconds. Agent Orange caused many people to starve to death. It has been reported, by the New York Times, that the herbicide destroyed 75 percent of the rice crops. Because people’s homes and crops were being destroyed, they were left homeless and hungry on the
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
