This causes muscular paralysis. The peripheral sensory nerves and the central nervous system are usually not affected. The toxin can be destroyed heat and cooking food at 80oC for 30 minutes, however, inactivation of spores requires a much higher temperature. This table summarizes the most common neurotoxin type affecting the various species affected
What causes it? • Chicken pox is caused by a very contagious infection caused by the varicella-zoster virus. • It is an airbourne virus, which means it is easily and rapidly spread through sneezing and coughing. Droplets of water expelled from the nose and mouth of the infected person are inhaled by those around them • The infection may also be caused by direct contact with the secretions from the blisters. • The varicella virus has an incubation period of between 10 and 21 days.
Bacteria is a single-celled microorganisms that cause diseases. Examples of bacteria are salmonella, campylobacteriosis, clostridium, and tularemia. Feline viral respiratory disease is a severe contagious illnesses of cats that spread fast in a multicat home. The fungi family comprises of mushrooms living in soil and biological material, most types of fungi are spread by airborne spores. “Rickettsia is a disease-causing parasites that are carried by fleas, ticks, and lice.
This group of viruses includes polioviruses, coxsackieviruses, echoviruses, and enteroviruses. Coxsackievirus A16 is the most common cause of hand, foot, and mouth. Also, Enterovirus 71 has been associated with outbreaks of the disease. The virus is easily spread through coughing and sneezing. Symptoms of hand, foot, and mouth disease include fever, blister-like sores in the mouth, and skin rashes.
The rodents in Asia had fleas and when fleas bit the animal that was carrying the disease the animal became infected. The fleas also produced larva in the fur which also had the bacteria called Pasteurella pestia. Once the rodents’ population decreased, the fleas went on to other animals this including humans. Some of the animals were often used for furs to
This was not true. You could catch this deadly plague from infested rodents, fleas, squirrels, or other wild animals. Indeed, the most efficient human vector of the plague was a flea known as Xenopsylla. cheopis. For you to catch the plague these steps would have had to happen first.
Rodents played a large roll in spreading Bubonic plague. Plague occurs in arias with a lot of burrowing rodents. During the renaissance rats were probably big problems. Any rat living in someone’s home or running down the street could be infected. Rodents also act as long term preservers for plague.
Plague It is little surprise that the plague was the most dreaded disease of Shakespeare's time. Carried by fleas living on the fur of rats, the plague swept through London in 1563, 1578-9, 1582, 1592-3, and 1603 (Singman, 52). The outbreaks in 1563 and 1603 were the most ferocious, each wiping out over one quarter of London's population. Lucky Elizabethans would contract the basic bubonic plague with their odds of survival around fifty percent. Symptoms would include red, grossly inflamed and swollen lymph nodes, called buboes (hence the name bubonic), high fever, delirium, and convulsions.
Melanie Ferrell POL 202- Dr. Dixon November 26, 2013 Civil Conflict and the Spread of Disease Introduction Civil conflict often dredges up images of horrible violence from one set of human beings against another. The words evoke thoughts of horrible atrocities such as the hacking by machete and awful mutilation of the Tutsi people by the Hutus in Rwanda or the merciless killing of innocents by the Janjaweed in Darfur just a few years ago. Another major factor within these conflicts is the spread of disease. Disease has often been used as a weapon by various armed factions in conflict, but it spreads just as easily naturally. This paper will explain how the spread of disease in civil conflict ridden areas is a result of the spread of refugees and travelers, the presence of terrorism in conflict areas which prevent proper aid to victims, and infected abandoned or wild animals that are ingested by starving peoples within a country.
What are foodborne illnesses? Foodborne illnesses are caused by eating food or drinking beverages contaminated with bacteria, parasites, or viruses. Harmful chemicals can also cause foodborne illnesses if they have contaminated food during harvesting or processing. Foodborne illnesses can cause symptoms that range from an upset stomach to more serious symptoms, including diarrhea, fever, vomiting, abdominal cramps, and dehydration. Most foodborne infections are undiagnosed and unreported, though the Centers for Disease Control and Prevention estimates that every year about 76 million people in the United States become ill from pathogens, or disease-causing substances, in food.
