DNA fingerprinting analysis of breakthrough outbreaks in vaccine-protected poultry stocks.
We report recurrent outbreaks of Yersinia pseudotuberculosis conjunctivitis in ducks and of fowl cholera in geese, occurring in stocks previously vaccinated with inactivated autogenous vaccines. Enterobacterial repetitive intergenic consensus sequence-based PCR and pulsed-field gel electrophoresis indicated reinfection with a new Y. pseudotuberculosis strain and vaccine evasion by the same Pasteurella multocida strain.
