''Bordetella'' species cause exogenous or endogenous infection which is of high morbidity and low mortality. They have poor survival in the environment. Transmission occurs between animals and young animals are particularly susceptible. Predisposing factors to ''Bordetella'' include stress and concurrent infections.
