IC02: Causes and spread of infection
1 Understand the causes of infection.
1.1 Identify the differences between bacteria, viruses, fungi and parasites.
Bacteria- needs time, moisture, warmth and food to develop, mostly
Develops in food industry due bad hygiene and cross contamination. It is treated by antibiotics mostly. Not all of them are bad. There for they are divided on:
Good- those who are benefiting human health, supporting various body functions (probiotics, stomach bacteria)
Harmless- those which have not benefit neither harm, but are essential to various processes (usually used when making blue cheese)
Pathogenic- these are causing illness and can be deadly (salmonella, ear infections, ect)
Viruses- all the smallest microorganisms air born or air float. Dead in air environment but came to live as so as they reach organism. Cured by own body antibodies or vaccinations. Not all of them are curable. (HIV) They are very resistible and quickly adaptable to vaccines, this is why there are very dangerous.
Fungi- simple plant like organism structure. Living in colonies.
For their growth they need moisture, warmth and good host. Mostly develop on feet. Not all of them are bad.
Division:
-Beneficial- (has healing properties)
-Harmless- have no nutritional value, but are not harmful
-Harmful- harmful usually located on feet or badly cleaned body area.
(Athletes foot)
Parasites-
Living organisms living on host drinking blood or other, without respect or symbioses to the host. (Looking after his own survival) Often attack human in subtropical areas where conditions are ideal. Some can be treaded easily some not.
1.2 Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites.
Viruses- Common flu, HIV, influenza, bronchitis
Bacteria- Salmonella, Lime disease, Diarrhoea, Vaginal problems
Fungi- Athletes foot, Yeast infections, Ringworm
Parasites-...
