They can lead to serious or sometimes deadly diseases, such as AIDS. Parasites: Parasite: parasite is an organism that lives on or inside another organism to the detriment of the host organism. These are of various forms and types. A parasite is an organism that lives on or in a host and gets its food from or at the expense of its host. Parasites can cause disease in humans.
They are single cell living micro-organisms. They live in groups of millions and multiply extremely fast, especially in warm temperatures. Bacteria is harmful to humans when it enters somewhere it shouldn't, this causes an infection such as food poisoning, diarrhoea, and legionaries disease. Viruses are small infectious agents that only live inside the cells of living things, in humans, animals and plants, a virus cannot reproduce. Viruses are harmful to humans because they infect the body tissue and cause infections such as the flu, norovirus and whooping cough.
Viruses are immune to antibiotics and can lead to very serious illness and deadly disease. Fungi are spore producing organisms such as yeast or mould, it re-produces via spreading spores and absorbs nutrients from any organic matter, they can cause disease especially in immune suppressed people, however from mould penicillin was developed, helping treat many illnesses effectively. Parasites are organisms that live in or on the body. They live and feed on the host and can cause infection and spread disease directly. Some can be treated easily with creams/medication others can prove harder to identify and treat as they are different the world over, depending on where you are/climate/flora and fauna.
For example, penicillin. Certain types of Fungi can cause illness such as Candida which is a yeast that can cause infections such as thrush. Parasities A parasite is a tiny organism that lives in or on a host for example a body which they use in order to feed. Parasites can cause severe illnesses; there are 3 main types of parasites: protozoa, helminths, and ectoparasites. 1.2 identify common illnesses and infections caused by bacteria, viruses, fungi and parasities bacteria • food poisoning • bronchitis • ear infections • throat infections e.g.
Moulds, yeasts), as well as more familiar mushrooms. One major difference from other organisms like: plants, animals, bacteria, etc., is that fungal cells have cell walls that contain chitin. Fungi can be killed by antifungal medicine. Parasite is a plant or animal or fungi that lives on or in other organism called the host to obtain nourishment without providing any benefit to the host. Parasites may be protozoa, yeasts or multicellular organisms.
Superbugs are a class of bacteria and viruses which have changed or mutated, becoming resistant or immune to antibiotics. One example of a superbug is methicillin-resistant Staphylococcus aureus or MRSA. Staphylococcus aureus also known as Golden staph is bacteria commonly found on the skin and in the noses of healthy people and it is usually harmless unless it enters into the body (Mosher, 2012). MRSA is most often transmitted by direct physical contact and not through the air. However there can be indirect contact by touching objects such as towels, sheets, wound dressings, clothes, sports equipment and workout areas contaminated by the infected skin of a person with MRSA (Gilboy, 2011).
Changes in climate or introduction of a new species from elsewhere can greatly affect the balance of nature. A virus is a small infectious agent that can replicate only inside the living cells of organisms. Most viruses are too small to be seen directly with a light microscope. Viruses infect all types of organisms, from animals and plants to bacteria and archaea. All viruses have genes made from either DNA or RNA, long molecules that carry genetic information; all have a protein coat that protects these genes; and some have an envelope of fat that surrounds them when they are outside a cell.
Some fungi mass together to create toadstools. They spread by releasing spores into the environment. Parasites These are microorganisms that depend on other organisms for survival. Bacteria and viruses can be parasites. 1.2 Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites Bacteria Lyme disease, Tuberculosis, tetanus, MRSA, whooping cough Viruses Polio, Norovirus, common cold, flu, chicken pox Fungi Ringworm, athletes foot, oral thrush Parasites Worms, ticks, lice, mites 1.3 Describe what is meant by 'infection' and 'colonisation' Infection Infection is the invasion on bodily tissues by disease causing microorganisms Colonisation Colonisation is when an invasion of disease or bacteria populate a specific area of the body which can cause the body's immune system to break down.
The purpose of this experiment was to determine the type of Staphylococcus (commonly referred to as Staph) that was isolated from the nose by performing a series of tests. Staph is a bacteria that is very often the cause of skin, stomach and blood infections. It is commonly found on the skin, but is easily disinfected with antiseptics or even soap and water. It is normally dealt with by the body's immune system pretty easily, and as such is very hard to catch directly from another infected person. However, Staph can enter the body through any opening (including cuts) and find its way into the bloodstream.
It’s a single celled yeast or a larger multi-cellarer mould, It can cause disease in immune suppresses people. Example of this is ring worms/back itch Parasites- 1.2 Bacteria- Salmonellioses, MRSA, food poisoning, bronchitis, ear infection, strep throat, tonsillitis, pneumonia. Gonorrhoea and clymedia Virus- Influenza, common cold, stomach fly, pneumonia, ear infection, hiv/aids, herpes and warts Fungi- Valley fever, athlete’s foot and yeast infection Parasites- worms, schistosomiasis, malaria and sickness 1.3 Infection- the process of infecting or being infected, invasion by and Multiplication of pathogenic microorganism in body part/tissues, can cause tissue injury and progress to disease through variety of cellular/ toxic mechanism Colonization- act or process of etsash a colony/colonies spread of a species to a new habitat 1.4 Systemic infection- affects number of organs and tissues, it can effect the whole body Localised infection- restricted infection and limited to a specific body/region 1.5 Inadequate hand washing, not wearing PPE, not being cautious wear food is involved, poor environmental hygiene and using equipment without sterilising 2.1 The conditions needs for growth of microorganisms is warmth, moisture and
