Term
how pathogens become opportunistic
Definition

-if a member of the normal microbiota in one site is introduced into a site it normally does not inhabit

-immune system (disease, malnutrition, emotional/physical stress, radiation/chemo)

-changes in the normal microbiota, normal changes, stress, change in diet, over exposure to pathogens

Definition
sites where pathogens are maintained as a source of infection
Term
zoonoses
