Fungi :A Fungus is a spore producing organism and can live as a single celled yeast or as a larger multi-cellular mould. It will live by absorbing certain nutrients from any organic matter. Fungi include moulds, mildews, Mushrooms and yeast. The more common illnesses from fungi could be athlete’s foot, ringworm and thrush. Viruses: A virus needs a host cell to replicate.
Some bacteria can fight off harmful bacteria helping to prevent illness. Viruses are a small infectious agent that replicates only the inside of living cells of other organisms. Viruses can infect all types of life forms, from animals to plants to micro organisms. Most viruses are too small to be seen with an optical microscope. Viruses can spread in many ways.
When a virus enters the body, it enters some certain cells and takes over making the now host cell make the parts the virus needs to reproduce, the cells are eventually destroyed through this process. The most common viruses is the common cold, which has no cure. Fungi Mould, yeast and mushrooms are all types of Fungi. Fungi live in the air, water, soil and on plants and they can live in the body, usually without causing illness. Some fungi have beneficial uses.
UNIT4223-008 Causes and spread of infection (IC02) 1.1Bacteria are living things that are neither plants nor animals but belong to a group all by themselves. They are very small individually, not more than one single cell however there are normally millions of them together, for they can multiply really fast. Bacteria are prokaryotes (single cells that do not contain a nucleus). Every species has great ability to produce off spring and its population expands until it runs out of food or it is limited by competition, its own waste products, or some other factor. Changes in climate or introduction of a new species from elsewhere can greatly affect the balance of nature; some bacteria help to digest food, destroy disease causing cells, and give the body needed vitamins, bacteria are also used in making healthy foods like yogurt and cheese.
Fungi are Eukaryotes when compared to bacteria and fungi. One major difference is that fungal cells have cell walls that contain chitin unlike the cell wall of plants which contain cellulose. The chitin adds rigidity and structured support to the thin cells of the fungus. A parasite is an organism that lives on or inside another organism to the detriment of the host organism. 1.2 Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites.
They replicate by invading targeted cells of their host and taking over genetic material responsible for reproduction. These are tiny infectious agents that are so small that even a light microscope will not detect them visibly, infecting all kinds of cells from bacteria, fungi, plants, animals and humans. Some of their common illnesses and infections include colds, influenza, chicken pox, measles, mumps, herpes, norovirus and cold sores. Fungi are simple plant like single-celled organisms, reproducing both sexually and asexually via spores. They take on various forms and can include yeast and moulds.
When a virus enters the body, it enters some certain cells and takes over making the now host cell make the parts the virus needs to reproduce, the cells are eventually destroyed through this process. The most common viruses is the common cold, which has no cure. Fungi Mould, yeast and mushrooms are all types of Fungi. Fungi live in the air, water, soil and on plants and they can live in the body, usually without causing illness. Some fungi have beneficial uses.
A parasite is any organism which lives inside a different organism in a symbiotic relationship in which only the parasite benefits from the symbiosis. This means that a parasite basically feeds off a host and the host suffers as a result of this. Parasites can be as small as viruses, or as big as metre-long tapeworms. The common illness and infections caused by bacteria, viruses, fungi and parasites are Pneumonia, Diarrhoea, Urinary infections, colds These are just a few of the common illness and the list can go on. what is meant by “infection” and “colonisation”?
There are also many properties of bacteria. It has prokaryotic (no membrane-enclosed nucleus), a single chromosome, and a closed circle of double-stranded DNA. It doesn’t have a mitochondria or chloroplasts. If you want to classify bacteria you have to know many things such as the shape. These are the three most common forms of bacteria -bacilli: rod shaped, cocci: spherical, and spirilla: curved walls.
Bacterial infections are commonly treated with antibiotics. A virus is smaller and more difficult to kill than bacteria. It cannot be treated with antibiotics. A virus needs a living host to replicate and cannot do so outside of a host cell. A virus is a small piece of genetic material that has a protein coating to protect itself.
