Pathogenesis of Bordetella bronchiseptica infection in cats

Bordetella bronchiseptica appears to occupy a position along a continuum with "pathogen" at one end and "commensal" at the other. The pathogenesis of Bordetella bronchiseptica (Bb) infection in cats is still unknown, but is expected to be comparable to that in other species.

Transmission of infection occurs between in-contact animals directly via intimate contact or by droplet infection. Bb does not survive for long periods outside the host and is readily killed by many common disinfectants and extremes of pH and temperature. However, in a heavily contaminated environment, particularly within infected mucus, survival may be long enough for indirect transmission to occur.
