Antibiotics can usually kill them. An example of bacteria is meningitis and pneumonia. Fungi: A fungus is a spore producing organism that has no chlorophyll and can live as single celled yeast or as a larger multi-cellular mould. It will reproduce by spores. It will live by absorbing certain nutrients from any organic matter.
Illnesses caused by viruses: Chickenpox, Common Cold, Hepatitis, Herpes, HIV, Influenza, Measles, Mumps, Noravirus, etc. Illnesses caused by fungi: Athlete’s Foot, Ringworm, Thrush ( Candida ), etc. Illnesses caused by parasites: Fleas, Lice, Scabies, Worms, Amoebic Dysentery, Malaria, etc. 3. Describe what is meant by “infection” and “colonisation” Infection is the invasion of the host organism’s bodily tissues by disease-causing organisms, they multiplication and the reaction of the body to these organisms and toxins they produce.
The most common (the one that most people think of when fungi are mentioned) are mushrooms, from shitake mushrooms to the death cap mushroom. Fungi are multicellular organisms, much like plants and animals (eukaryotic organisms) unlike viruses and bacteria (prokaryotic organisms) which are single cell organisms. One major difference is that fungal cells have cell walls that contain chitin, unlike the cell walls of plants, which contain cellulose. The chitin adds rigidity and structural support to the thin cells of the fungus, and makes fresh mushrooms crisp. Parasites: a parasite can be a bacteria, a virus, a fungus, algae, plant or animal.
2.2 Identify Common Illnesses and Infections Caused by Bacteria, Viruses, Fungi and Parasites * Bacteria – Salmonella, E-coli, tetanus, typhoid fever, cholera * Virus – Aids, common cold, cold sores, influenza * Fungi – Athletes Foot, candidoses, ringworm * Parasites – Ticks, fleas, lungworm 2.3 Describe what is Meant by ‘Infection’ and ‘Colonisation’ Infection is the invasion of a living host’s bodily tissue by disease causing organisms that multiply in the body and cause illness. Colonization occurs when one organism or more populate an area. Bacteria colonize on an area of the body surface and do not cause
1.2 identify common illnesses and infections caused by bacteria, viruses, fungi and parasities bacteria • food poisoning • bronchitis • ear infections • throat infections e.g. tonsillitis • chlamydia • impetigo • mrsa • tb viruses • influenza • cold • hiv/aids • stomach flu • pneumonia • warts • chicken pox fungi • athletes foot • ringworm • yeast
Since a parasite is something that infects the body, they can cause infectious disease. 1.2 Illnesses/infections caused by bacteria can
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
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. 1.4 Explain what is meant by 'systemic infection' and 'localised infection' Systemic infection This is where infection spreads throughout the whole body or affects several organs or tissues. Conditions like type 2 diabetes or AIDS are examples of this. Localised infection This is confined to one organ system or area in the body e.g. abscess or boil.
Identify the difference between bacteria, viruses, fungi and parasites The difference between bacteria, viruses, fungi and parasites is; bacteria is a one-cell micro organism that can multiply very fast; viruses are small cells that can only reproduce on a living host; fungi is a cell that lives on a dead organic material so that it can grow and get nourishment. Identify common illnesses and infections caused by bacteria viruses, fungi and parasites Bacteria staphylococci (MRSA) which lives on the skin can cause different infections with people that have low emun system Viruses hepatitis (A-E) is where damage to your liver means a virus can start and reproduce causing different effects to the body depending on what type of virus it is. Fungi candidiasis which is a build up of yeast in the body such as athlete’s foot. Parasites scabies this is where a skin mite is passed on by direct contact from another person. The skin mite then can lay eggs within the skin causing a rash and very itchy skin.
All viruses have genes made from either DNA or RNA, 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. Fungi: Like plants and animals, fungi are multicellular organisms. One major difference is that fungal cells have cell walls that contain chitin, unlike the cell walls of plants, which contain cellulose.The chitin adds rigidity and structural support to the thin cells of the fungus, and makes fresh mushrooms crisp Most members of the kingdom Fungi lack flagella; the structures are completely absent in all stages of their life Parasites: A 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
