There are several types of parasites such as Ectoparasite- which is a parasite that lives on the host’s surface, examples will be hair and body lice and mites. Endoparasites – One that lives inside the host, for example heartworm, tapeworm and flatworms. Epiparasite- This one feeds on another parasite. For example, fleas and ticks. 1.2 Identify common illness and infections caused by bacteria, viruses, fungi and parasites.
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
Plants, animals, humans, fish, birds and reptiles can all be host to parasites. Head lice, thread and other worms are all parasites; they survive by feeding on the blood of their host. Some bacteria and viruses could be considered parasites. 1:2 Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites Bacterial Infections: Salmonellas/ food poisoning, tuberculosis/TB, MRSA, coccidiosis, food poisoning, dysentery, bronchitis, ear infections, tonsillitis. Viral
They are contained in a protein coating which makes them more difficult to destroy. Virus cells are shaped like rods, spheres or tiny tadpoles. They reproduce by invading cells in our body. Viruses can be more serious and are responsible for causing a variety of diseases for example, Norovirus, AIDS, HIV, influenza, small pox and measles. There are different types of fungi for example mushrooms are a fungi and some cheeses have fungi in them, however fungi can also cause illnesses such as Candida, this is yeast that causes infection.
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.
They draw nourishment and other needs from their host organism. Parasites that cause infection and disease are known as Pathogenic parasites Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites Virus Common cold, flu, mumps, measles, Chicken pox, Cold sores, HIV,
Causes and Spread of Infection 1. Understand the causes of Infection 1.1 Identify the differences between bacteria, viruses, fungi and parasites The differences between bacteria, viruses, fungi and parasites range. One of which is the fact that viruses and parasites depend upon a living host to survive, while bacteria and Fungi's don't always need to do so. Another difference is that Parasites are normally living creatures - ticks, fleas, worms - whilst bacteria, viruses and fungi are cells that have different cell coatings. 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.
Viruses are small infectious agents that replicate only inside the living cells of other organisms, Viruses infect all types of life forms from animals, plants and bacteria. The average of virus is about one hundredth the size of average bacterium. Viruses spread in many ways; viruses in animals can be carried by blood-sucking insects. Viruses can be carried in the air and spread by coughing and sneezing, food, water and person to person contact are also means of transmitting a virus. Several viruses inc. H.I.V.
The Bubonic Plague is the most common out of all the plagues. This is a result of when a person is bitten by a rat flea. This causes Painful swellings called buboes. Buboes mostly appear in the legs, neck, armpits, and groin. The plague bacilli are little toxin factories.
Raven Johnson Mr. Montgomery 3/14/12 Bubonic Plague The Bubonic Plague is a deadly infectious disease, which is caused by the bacterium Yesinia pestis. It is transmitted through the bite of a flea, and has killed millions of people. This plague is one of the most feared of all diseases (McNeill, W. H.). It is easily transmittable and has a high mortality. It can be cured through antibiotics (McNeill, W. H.).
