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.
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 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,
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. Fungi are also responsible for skin problems such as, oral thrush, athlete’s foot and ringworm. A Parasite is an organism that lives inside another organism, which is known as the host. The host can be for eg, a human being, animal. The parasite is dependent on its host for survival, it has to be in the host to live, grow and multiply.
Outline Worksheet for Informative Speech Title: West Nile Virus Speaker: Joseph N. Aranbayev Specific Purpose: Problems and solutions associated with the West Nile virus Thesis Statement: People must understand the nature of the West Nile virus and how people get infected with it in order to take the necessary steps to protect themselves. Introduction I. Since it’s migration to the U.S. in 1999, the West Nile virus (WNV) has claimed over a thousand lives and has been found in a total of 27,605 people. (Lee, M.C. 23-34) II.
Some of the most deadly diseases and devastating epidemics in human history have been caused by bacteria. Cholera Diphtheria Dysentery Plague Pneumonia Tuberculosis Typhoid Typhus VIRUSES A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms, from animals and plants to bacteria and archaea. The average virus is about one one-hundredth the size of the average bacterium. Most viruses are too small to be seen directly with an optical microscope.
Parasites are organisms that live within other organisms, called the host and it will often harm it. Parasites will reproduce at a very high rate and can also spread. There are three main types of parasitic diseases, these are protozoa which are a single celled organism and can only multiply within the host; helminths which is worm parasites and arthropods which include insects and spiders, the insects
Malaria is a contagious disease caused by five different Plasmodium parasites that have similar life cycles.1 These parasites have a complex life cycle that requires an insect vector most commonly female Anopheles mosquito and a human host. The life cycle of the malaria parasite is composed of human stages and mosquito stages.2 The discovery of the first stage during which the parasites develop in the liver before entering the blood stream was done by Henry Shortt and Cyril Garnham in 1948. In 1982, another discovery was made by Wojciech Krotoski demonstrating the presence of dormant period in the liver that occurs in the final stage. These discoveries play an important role in the understanding of the life cycle of malaria prasites.1 Moreover,
Parasites survive by feeding from its host. 1.2 Bacteria, common illnesses caused by bacteria are MRSA, Salmonella, Legionnaires disease, food poisoning, Pneumonia and Bronchitis. Viruses, common viruses are A common cold, measles, chicken pox and HIV. Fungi, common fungi are, Athletes foot, Ringworm and yeast infection. Parasites, common parasites are, Malaria and worms.
According to global polio surveillance data from October 23, 2013, 301 polio cases have been reported from the following countries: Afghanistan, Cameroon, Nigeria, Pakistan, Ethiopia, Kenya, Somalia, and South Sudan. In 2012 there were 223 cases reported in 5 different countries:Afghanistan, Chad, Niger, Nigeria, and Pakistan. Of the 2012 polio cases, 97% (217 of the 223 cases) were reported from the three remaining endemic countries. Polio is spread when the stool of an infected person is introduced into the mouth of another person through contaminated water or food (fecal-oral transmission). Oral-oral transmission by way of an infected person's saliva may account for
