Front 1

pathology

pathogens

Back 1

pathology- study of disease

pathogenicity- progression of disease

pathogens- organisms that cause disease

Front 2

infection

disease

Back 2

infection- colonization success in body, may not result in disease

disease- from colonization, spread to damaging effects

Front 3

flora

Back 3

normal flora- bac org reside in body, permanent (rest of life), throat, intestine, skin

microbial antagonism

transient flora- not permanent, guests come and go

Front 4

normal flora

Back 4

1. competitive inhibition- inhibition by competition, can't out grow space, keep system in check (keep harmful under control)

2. keep immune system alert

activa- clean out bad bac

vary on health, ph, temp, env
