Document Summary
Disciplines used in diagnosis, treatment, control of disease. Disciplines used in lab investigation of biological systems (e. g. disease) E. g. pathology, oral health therapy, nutrition, oral health therapy. Biochem follows binomial system (2 components; genus and species) Genus / species name italicised or underlined, e. g. staphylococcus aureus. Genus may be abbreviated to first letter after using full name once in text, e. g. s. aureus. "informal designation" (plurals ending in i) are not italicised or capitalised, e. g. staphylococci. Have important role in food chain e. g. decomposition, nitrogen fixation. Become pathogenic when placed in different conditions e. g. bowel flora that find their way into the bladder. Usually cause disease when found in the human body e. g. syphilis, tuberculosis, anthrax. Microbes that naturally inhabit surfaces of the human body. Total microbial load > 10^13 microbial cells in the body vs. 10^13 body cells. Possible as microbes are much smaller than body cells.
