Parasites can cause disease in humans. Some parasitic diseases are easily treated and some are not. The burden of these diseases often rests on communities in the tropics and subtropics, but parasitic infections also affect people in developed countries. Bacteria, fungi and viruses are all very different from one another. A big
Once in the bloodstream or digestive system, the bacteria can be life threatening as it will spread and multiply rapidly. Staph infections are easily treated with common antibiotics. However, a form which was once found only in hospitals (MRSA), but is now widespread, is resistant to most known antibiotics and can only be treated with expensive narrow spectrum antibiotics. Aside from your skin, a favorite place for Staph and MRSA bacteria to live and grow is in your nose. Bacteria like Staph love moist and warm places like the nose, upper respiratory system, groin and arm pits.
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. If the MRSA bacteria penetrate deeper inside your body or into your blood, they can cause serious infections. These invasive MRSA infections signs may include having a fever, chills, dizziness, confusion, muscular aches and pains 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.
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.
They live on or in their host for an extended period of time. Fungi comes in many different forms, some of which we eat (such a yeast and mushrooms). Other forms include moulds. Some forms of fungi can cause serious harm to humans. 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.
Is it Contagious? Necrotizing Fasciitis is a horrible disease that affects the skin and soft tissue beneath it. It is a disease of the skin and surrounding tissues, it is contagious, and it is potentially deadly. Necrotizing Fasciitis is also known as “flesh-eating bacteria”. It is a rare bacterial infection that invades the skin and tissues under the skin.
When MRSA infects skin, a swollen, red area develops, and it is usually painful. MRSA skin infections may develop pus or weep other fluids. If left untreated, a MRSA skin infection can go progressively deeper into the body, infecting blood and organs. Symptoms of MRSA infection can include chills, cough, chest pain, fever, fatigue, muscle aches, rashes, shortness of breath and a general feeling of malaise. The worst and final symptom of progressed MRSA infection is death Read more: http://www.foxnews.com/health/2012/05/08/mrsa-antibiotic-resistant-bug-that-has-health-officials-worried/#ixzz2UnSQcGzS When MRSA infects skin, a swollen, red area develops, and it is usually painful.
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.
Unit IC02 Cause and spread of infection outcome 1 1.Identify the differences between bacteria, viruses, fungi, parasites Bacteria – bacteria are extremely small singular organisms which are found almost everywhere. Viruses – it is a coated genetic material that invades cells and use’s the cells apparatus for reproduction.Fungi – it is a multi-celled living organismParasites – they are types of living plants and animals that derive benefit from the metabolism of other animals and plants. 2. common illness and infection caused by bacteria, viruses, fungi and parasites Bacteria – Food poisoning, bronchitis, ear infections, tonsillitis. Viruses – common cold, stomach flu,warts .Fungi – Athletes foot, ring worm, yeast infection.Parasites – worms, malaria, trypanosomiasis (sleeping sickness) 3. describe what is meant by infection and colonisation Infection – is an invasion to body tissues from a disease- caused micro-organism.Colonisation – is multiplication of micro-organisms without tissue invasion or damage. 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.
