Abstract |
|---|
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-PCR and pulsed-field gel-electrophoresis indicated reinfection with a new Y. pseudotuberculosis strain and vaccine evasion by the same Pasteurella multocida strain.
