Bacterial infections are commonly treated with antibiotics. A virus is smaller and more difficult to kill than bacteria. It cannot be treated with antibiotics. A virus needs a living host to replicate and cannot do so outside of a host cell. A virus is a small piece of genetic material that has a protein coating to protect itself.
Bacterial infections can usually be treated with anti-biotics however some types of bacteria can form a protective spore which can make them more resistant to heat and chemicals. The requirements for optimum growth are is a temperature of 37c, water, food, time, oxygen/ no oxygen. Common illnesses caused by bacteria are Salmonella, tuberculosis, MRSA, bronchitis, ear infections and tonsillitis. Virus-tend to be smaller than bacteria and in order for the cells to reproduce they need to be in a living host. The common way of treating a virus is through immunization as anti-biotics will not be effective against viral infections.
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.
CAUSES AND SPREAD OF INFECTION Outcome one:- The differences between bacteria, virus, fungus and parasites. Bacteria :- they are small single-celled life forms that reproduce quickly and are capable of causing disease. Antibiotics can be used to treat infections caused by bacteria although some can form a protective spore which can make them more resistant to heat and chemicals. The requirements for optimum growth are is a temperature of 37c, water, food, time, oxygen/ no oxygen. Virus:-These are smaller than bacteria and need to be in a living host to cell reproduce, the principal way of control is immunisation, antibiotics are not affective against viral infections.
what is meant by “infection” and “colonisation”? Infection is something that is picked up through bad hygiene Colonisation is where an infection enters the body and grows. An infection is the colonisation of a host of organisms that enter the body and multiply. A systemic infection is one that affects the whole body, probably travelling in lymph or blood. This is in contrast to a local infection which only affects the area where the infection entered.
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.
4. Molecular Diagnosis Parasite nucleic acids are identified by using the polymerase chain reaction (PCR). Even though this technique may be somewhat more susceptible than microscopy, it is of restricted effectiveness for the diagnosis of acutely ill patients in the standard healthcare setting. PCR results are often not obtainable rapidly enough to be of value in establishing the diagnosis of malaria infection. PCR is mostly beneficial for verifying the species of malarial parasite after the diagnosis has been recognized by either microscopy or RDT.
You must be kept cold 3. You must cook food thoroughly When food is contaminated by bacteria it may cause gastro-enteritis. Gastro-enteritis is the “inflammation of the stomach and intestines, typically resulting from bacterial toxins or viral infection and causing vomiting and diarrhoea”(1). this can be very serious. Bacteria can get into food in various ways such as having dirty hands, dirty work surfaces, dirty drying up towels, uncooked meat and poultry, dirty sinks and draining pipes, fingers or spoons being licked , flies and so many others to get in contact with bacteria.
Re-using Medical Equipment The following diseases are known to be ones that can cause different types of infections in a healthcare setting: 1. Klebsiella pneumonia is a gram negative bacterium that is normally found in the intestines, where it does not cause disease. It is also found in the stool. In a healthcare setting, however, it can cause infections such as pneumonia, wound or surgical site infections, blood stream infections or sepsis, and meningitis. Klebsiella is mostly spread through person to person contact with contaminated hands.
It is caused by the imbalance of bacteria in your vagina. Normally, the vagina houses more good bacteria then bad bacteria. The good bacteria is called lactobacilli which keep the environment healthy and bad bacterias at bay. However, with pregnancy it tends to be more common to have an imbalance and no one is
