Document Summary

Immunology = study of our protection from foreign macromolecules or invading organisms and our response to them. Bacterial populations can be either resident or transient: Resident: always present i. e. : large number of anaerobes and coliform organisms in the colon. Transient: in a specific location, such as skin, often because of displacement of resident flora, injury or trauma, or through human behaviour. Infection of bacteria occurs when a single species becomes predominate at a site at which there is normally any species or when a single organism invades a body site that is normally sterile. Physical and natural structures that are produce every time to protect the body from unknown substances i. e. : skin, saliva, mucous, tears, hairs, etc. Antibodies, complement, immune cells (t0cells, nk cells, macrophages), immune syst. When unwanted substance get in, the other helpers look for them to destroy them. New born do not have all this factors as their immune system is not fully developed.
