Fungi Fungi are skin infections caused by dermatophytes and yeasts, which are groups of fungi that are normally harmless. When these grow excessively, it causes symptoms and usually affects your skin because they live of keratin. Parasite A parasite is a life-form that survives off its host, including worms, bacteria, protozoa and amoeba. Parasites often work by stealth—you probably don’t even notice their presence. In the meantime they rob your system of nutrition, loading you down with their excretions and secretions these include Lice and Ringworm 1.3 Colonisation is when a bacterial strain invades a region of your body and starts to rapidly divide - it sets up a new colony Infection is similar but only usually used for opportunistic pathogenic bacteria - that is it does not usually refer to bacteria that normally inhabit us 1.4 Localised infection is restricted to a ceratin region of your body Systemic infection means that the infection is throughout your body.
Other fungi can cause illness. One example is Candida — a yeast that can cause infection. Candida can cause thrush — an infection of the mouth and throat — in infants and in people taking antibiotics or who have an impaired immune system. Fungi are also responsible for skin conditions such as athlete’s foot and ringworm. A parasite is an organism that lives on or inside another organism to the detriment of the host organism.
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.
1.2 Identify common illness and infections caused by bacteria, viruses, fungi and parasites. Viral and bacterial infection Viruses: Viruses can affect many different parts of the body or more than one body system at the same time for example a runny nose, sinus congestion, cough or body ache. Viruses can cause the classic common cold or even the flu, much
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.
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
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.
1.1 & 1.2 Bacteria~ These are single cells that can divide and multiply rapidly and come in different shapes and divide anywhere such as M.R.S.A, septicaemia and gastro-enteritis. Viruses~ Are ready made stable D.N.A with a protective shell, they cannot invade without the assistance of another cell to do so, examples of these are the common cold, flu and hepatitis. Fungi~ Are simple plants such as yeasts and moulds or even rusts that thrive in moist, dark, unventilated areas like thrush, ringworm or athlete's foot. Parasites~ Are animals or plants living in or on the host, usually small creatures that are living on or within us such as lice, scabies, tapeworm or threadworm. 1.3 What is meant by….
It begins at the site of a break in the skin (a surgical or non-surgical wound). In order for someone to contract necrotizing fasciitis, the bacteria must be introduced into the body. Group A Strep is the same bacterium that causes strep throat This group of bacteria is responsible for mild cases of sore throat (pharyngitis), skin infections, as well as rare, severe illnesses such as toxic shock syndrome and necrotizing fasciitis. However, there are various strains of the bacteria, some of which are more powerful than others. With the right set of conditions, necrotizing fasciitis is a real risk and can cause severe damage.
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.
