The bacteria commonly exist in rivers and lakes, are often found in any warm water system or device; air conditioning cooling towers, whirlpool spas, humidifiers, faucets and shower heads, anywhere artificial water is being supplied or used, and any place where water is stagnant. People contract Legionnaires by inhaling small droplets of the contaminated water. The disease has not been proven to pass from person to person. The likely hood of contracting the disease depends on the level of contamination of the source, health and age of the person exposed, and the intensity of the exposure. Most cases are a single isolated case, but outbreaks may occur.
The common way of treating a virus is through immunization as anti-biotics will not be effective against viral infections. The virus infection can cause things like the Influenza, common cold, stomach flu, pneumonia, blood born infections, ear infections and HIV/AIDS. Fungi- live in the air, water, soil and on plants and they can live in the
Causes and spread of infections 1 Understanding the cause of infection Bacteria can be both beneficial and pathogenic. These single cell micro-organisms are tiny living beings, neither plant or animal, that normally exist together in millions and reproduce only asexually. Some of their common illnesses and infections include ear infections, food poisoning, urinary tract infections, diphtheria, bacterial meningitis, gastritis and sinusitis. Viruses differ from bacteria, being coated genetic material and in that they do not reproduce on food, needing a living host to do so. They replicate by invading targeted cells of their host and taking over genetic material responsible for reproduction.
Bacteria cause bacterial diseases as viruses cause viral diseases. However, these two types have many things that separate them to become different from one another. For instance, there are not as many ways to treat a viral disease as there are to bacterial. Antibiotics can treat bacterial diseases while viral diseases can only have their symptoms suppressed by antibiotics. In another case, both types of diseases can be prevented only with certain steps.
(Chaudry, 2011, para. 5) Botulism also impairs the neuromuscular junctions. The release of the Botulinum toxin will eventually lead to respiratory and musculoskeletal paralysis. (Chaudry, 2011, para. 5) Botulism can also be contracted through an open wound.
Back before the 1890’s Clostridium perfringens used to be known as Clostridium welchii. F.W. Andrews and E. Klein discovered that Clostridium perfringens was associated with food poisoning, and in just a couple years specifically 1892, this microorganism would be found in different types of gangrene, appendicitis, puerperal fever, and enteritis. (3) .. Gas gangrene was very widespread in World War 1, complicating 6% of open fractures and 1% of all open
1.2 Common illnesses and infection caused by Bacteria include Salmonellosis, MRSA, Food Poisoning tonsilitus, gonorerhea bronchiolitis strep throat syphilis and chlamydia. Viruses – Influenza, common cold warts herpes stomach flu Fungi – thrush (yeast infection) athletes’ foot Parasites – Worms - Malaria 1.3 Infection means an illness caused by growth of a germ on or in a living person it can make you sick signs could be fever, puss from a wound or pneumonia, When germs are commonly found on the body without causing an illness it’s called COLONISATION. 1.4 Systematic means it’s in the bloodstream and its spreading through the body, sepicemia is an example of systematic infection. Localised infection is where it’s restricted to a small area only i.e. infected cut /
But an injury can inflame the cornea without a secondary infection occurring. Viral keratitis occurs quite commonly and the types of viruses include: Adenovirus, which is one of the causes of upper respiratory infections. Herpes simplex type 1, and Varicella zoster. Bacterial keratitis occurs less often than viral keratitis. Infectious keratitis usually begins by affecting the outer layer of the cornea, but it can go deeper into the cornea, increasing the risk of impaired vision.
Toxin produced is responsible for the infection Staphylococcal toxins can also act as superantigens Cleaning and removal of dirt reduces rates of infection Antibiotics, resistant strains 2. Streptococcus pyogenes: Group A Strep “Flesh-eating” bacteria Necrotizing fascitis. Bacteria multiply in dead tissue, producing toxin which kills tissue, muscle Superantigens Antibiotics are of little value in killing bacteria as the circulatory system which would carry the drugs, does not function in the dead tissue, sometimes amputation may be needed. 3. Pseudomonas aeruginosa: is the prime cause of life threatening burn infections.
These include anaerobic conditions (such as rotting carcasses or canned food), warmth, and mild alkalinity. The photo shows the bacillus shape of the bacterium C. botulinum. After germination, clostridial spores release neurotoxins. There are 7 antigenic types of neurotoxins, classified as A through G. Typically, different neurotoxin types affect different species. Only a few nanograms of these toxins can cause severe illness.
