Clearing may take place from the center out, leaving a bull's-eye effect; in some cases, the center gets redder instead of clearing. The rash may look like a bruise on people with dark skin. Of those who develop Lyme disease, about 50% notice flu-like symptoms, including fatigue, headache, chills and fever, muscle and joint pain, and lymph node swelling. However, a rash at the site can also be an allergic reaction to the tick saliva rather than an indicator of Lyme disease, particularly if the rash appears in less than three days and disappears only days
) most important * If it progresses and will go to the heart and kidneys and then eventually cause death * Mites lice, and ticks can spread this as well * The rocky dog tick that cause this disease usually * The tick has to feed for 4 hours to be able to spread the disease * Zoonosis - is a disease that humans gets from animals other than humans * Borreliaburgdorferi(also known as lime disease ) * Cause by deer ticks (smaller then dog ticks ) * Gram negative * This was found in lime coneticit (state) * Came from England and spread to the united states * Lime disease comes in three
This bacterium is also a facultative anaerobe meaning it can grow with or without oxygen. The bacterium is found most commonly in animals such as rats, fleas, lice, chipmunks, etc. Y. pestis is most commonly transferred through bites from affected animals, direct contact with infected tissue or body fluids, or inhaling infected droplets. The best way to avoid the plague would be to stay away for any animal that has potential for having Yersinia pestis If proper safety measures are not taken and a human ends up with the plague they would have general symptoms such as inflamed lymph nodes, fever, chills, muscle aches, headache and weakness. 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.
Given that mycotoxins may have carcinogenic properties, you should immediately remove yourself from any black mold environment and have the spores professionally removed. Black Mold vs. Other Molds • All molds can potentially cause respiratory symptoms as the spores enter your lungs, but not all molds contain pathogens or mycotoxins. Some of the more common household molds, like Penicillium and and Cladosporium, are far less harmful and only pose a threat to asthma sufferers and people with respiratory conditions. The toxigenic molds, like Aspergillus and of course black mold, can pose a threat to
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.
1.2 Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites The most common illnesses and infections that occur due to bacteria, viruses, fungi and parasites are Dioreah, Vomiting, Influenza, Nail infections, Tick bites, Colds, Skin Conditions, Digestive Problems ( Parasites - Worms ) and in some cases, Death. 1.3 Describe what is meant by “Infection” and “Colonisation” As defined by : www.freedictionary.com INFECTION Invasion by and multiplication of pathogenic microorganisms in a bodily part or tissue, which may produce subsequent tissue injury and progress to overt disease through a variety of cellular or toxic mechanisms. This means that Infection is the process of infecting or being infected. COLONISATION A mass of microorganisms in a culture that originates from a single cell. This means that when either a Virus, Bacteria, Fungi or parasites in the single form, gather and join to make one mass of either Virus, Bacteria, Fungi or parasites.
(Walker, 1996) These mechanisms play a more important role than antibodies which explains why vaccines are not effective for RSMF. (Walker, 1996) Pathophysiology of Rocky Mountain spotted fever (Rickettsia rickettsii) The primary vector for Rickettsia rickettsii, ticks, become infected through feeding on the blood of infected animals either by transovarial passage or fertilization. (Cunha, MD, 2014) The bacterium is transferred to humans during feeding. (Cunha, MD, 2014) The tick need to be attached to the host for 6-10 hours in order for the bacterium to be transmitted through saliva. (Cunha, MD, 2014) Rickettsia rickettsii has an incubation period of 2-14 days after the bite of an infected tick.
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.
Yesinia Pesties is gram-negative which means that antibiotics are less effective on the plague because of a lip polysaccharide layer over their walls that add extra protection. The bubonic plague has a major impact on the lymphatic system. The lymphatic system is made up of lymph nodes, lymphatic vessels, lymphoid organs and circulating lymphocytes. Plague victims tend to have large bumps on their bodies which are called "buboes". These are actually swollen lymph nodes filled with puss.
