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.
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.
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 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.
What is Clostridium botulism? Botulism is a rare but serious paralytic illness caused by a nerve toxin that is produced by the bacterium Clostridium botulinum and sometimes by strains of Clostridium butyricum and Clostridium baratii. There are five main kinds of botulism. Eating foods that contain the botulinum toxin causes Foodborne botulism. Wound botulism is caused by toxin produced from a wound infected with Clostridium botulinum.
They can lead to serious or sometimes deadly diseases, such as AIDS. Parasites: Parasite: 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 food from or at the expense of its host. Parasites can cause disease in humans.
1.1 Identify the differences between bacteria, viruses, fungi and parasites Bacteria are microscopic living organisms, usually one-celled, that can be found anywhere. Viruses are an infective agent that typically consists of a nucleic acid molecule in a protein coat and is able to multiply within living cells. Fungus is any member of the group of eukaryotic organisms which includes both unicellular microorganisms and multicellular fungi. Parasites are an organism that lives in or on another organism and benefits by deriving nutrients at the other's expense. 1.2 Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites Bacteria commonly causes strep throat, urinary tract infections, tuberculosis, etc.
Giardia lamblia is a single celled organism that causes a diarrheal infection of the small intestines and is one of the most common parasites in the United States. Giardia lamblia is a flagellated protozoan parasite which means it is an organism with one or more whip-like organelles called flagella. Flagellum is a hair like appendage that protrudes from the cell body, and it is how the organism moves around. The infectious agent can be transmitted by ingesting or swallowing water, food, or soil that is contaminated with giardia cysts (hard shells containing giardia). Some examples would be public swimming pools or spas.
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.
A Parasite is an organism that lives within another organism (the host). It is dependant on the host for its survival as it cannot live independently. 1.2 Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites. Common illnesses and infections caused by bacteria, viruses, fungi and parasites are: Bacteria: Salmonella, tuberculosis, MRSA, food poisoning, tonsillitis Viruses: Common cold, warts, AIDS/HIV, ear infections, influenza, Fungi: Athletes foot, yeast infection, ring worm, valley fever Parasites: worms, malaria, schistosomiasis, leishmaniasis, african trypanosomiasis 1.3 Describe what is meant by 'infection' and 'colonisation' Infection is the invasion and multiplication of microorganisms that are not normally present within the body. An infection tends to show symptoms and may spread through the whole of the body.
