Buiberstenia trehalosi
Mannheimia haemollyticum
Where are Pasteurellaceae found?
oral and respiratory tracts - mucous membranes
opportunistic bacteria
Define endogenous infection
already present in body but previously asymptomatic
carrier state
Define exogenous infection
infection from non-commensal enter a host
originate outside organism
