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.
CU254- Causes and spread of infection 1.1 Bacteria- single celled organism essential for all life, parasites or live independently. They multiply themselves by cell division. Antibiotics can usually kill them. Examples of this is meningitis/ pneumonia Virus- Microscopically small and simplest micro biological. It is not an independent living organism it needs a host to replicate.
There are four natural forms of botulism: food borne, infant, wound, and adult intestinal colonization (1). Food borne botulism (typically type A, B, or E toxins) is caused by ingesting food that has been in contact with contaminated soil and contains the spores. Improper canned goods and garlic/pepper infused oils with low acidity, high water activity, low concentration of salt, and no preservatives offer the organism a favorable anaerobic and nutritional environment to grow and produce the toxin (4). The spores are heat resistant and can survive improper prepared foods (5). Although, boiling canned goods for more than ten minutes will destroy the toxin (2, 5).
Outcome 1 Understand the causes of infection 1. Identify the differences between bacteria, viruses, fungi and parasites Bacteria are one-cell microorganisms with a single cellular organization, bacteria can reproduce from the life cycle and can be killed by antibiotics. Viruses are pieces of nucleic acid (DNA or RNA) wrapped in a thin coat of protein that replicate only within the cells of living hosts, viruses are smaller than bacteria and can’t be killed by antibiotics. Fungi are a member of a large group of eukaryotic organisms that includes microorganisms (eg. Moulds, yeasts), as well as more familiar mushrooms.
The infection on the skin usually first develops a painful bump or mark in the skin like an insect bite (Davis, 2012). The bacteria often enter into the skin through opening in the skin, which can develop into a painful pus-filled swelling or boil. Infected people can also have additional symptoms such as high temperatures and the general feeling of being unwell. MRSA infections can also have abscess where it causes larger, pus-filled lumps to develop underneath the skin. More extensive skin infection such as cellulitis, a bacterial infection of the deeper layers of skin and the layer of fat and soft tissues under the skin can also be contracted.
Finally, avoid contact with people who show signs of sore throat. There are a couple of treatments, also; they are surgery that removes infected tissues, antibiotics and intravenous immunoglobulin, treat complications, and hyperbaric oxygen therapy. This “flesh-eating bacteria” is something that will ruin patients’ lives if they catch
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.
This is harmful because they could pass it to another person and not even have knowledge of it. If there is a cut in the skin staphylococci bacteria will enter the body and cause the staph infection. There are different forms of Staphylococcus. Staphylococcus food poisoning is an illness is caused by eating foods that are contaminated with the staphylococcus infection. This is usually caused when a person who works with food has the staphylococcus infection and they do not wash their hands properly before he/she handles the food.
4. explain what is meant by systemic infection and localised infection Systemic – is when infection is distributed throughout the whole body.Localized – is when infection is limited to a specific part of the body. 5. identify poor practices that may lead to the spread of infection If you don’t wash your hands, not wearing personal protective clothing, not clearing surroundings, not covering your mouth and nose when you sneeze or cough. Outcome 2 1.explain the conditions needed for the growth of micro-organisms Most micro-organisms need most of the things you and I need to flourish and grow - moisture, warmth and a source of nutrition - some (usually the most dangerous such as those responsible for some types of gangrene) can do without oxygen (anaerobic bacteria). They need a mode of spread (usually the unwashed or poorly
Signs of an asthma attack are tight chest, cough, and wheezing. People with asthma respond to different risk factors. Risk factors are things that can start asthma attacks. It is important to know which risk factors start your asthma attacks. Some risk factors are animals with fur, cigarette smoke, dust in beds and pillows, dust from cleaning, strong smells and sprays, pollen from trees and flowers, the weather, colds, and sports or hard physical activity.
