Abstract
Riemerella anatipestifer infection accounts for the most significant economic losses due to infectious disease in commercial White Pekin ducks in the United States. An inactivated bacterin and a live attenuated vaccine are approved for use against R. anatipestifer in the United States. This study aimed to evaluate the duration of protection induced by the commercial bacterin containing formalin-inactivated strains of R. anatipestifer serotype 1, 2, 5 (RA1, RA2, RA5) combined with E. coli 078 (RA-EC). Pekin ducks were vaccinated twice at 2 and 3 wk of age with 0.5 mL of RA-EC bacterin containing approximately 108 colony forming units (CFU) of E. coli and 109 CFU of RA1, RA2 and RA5 per dose (0.5 mL). Four-, 6-, and 8-week-old vaccinated and non-vaccinated control ducks were subsequently challenged with virulent strains of either: E. coli 078, RA1, RA2 and RA5. Evaluation of the vaccine protective index, histopathology, and bacteriology indicate RA-EC bacterin provides protection against virulent stains of RA1, RA2, RA5, and E. coli O78 throughout the 8-wk commercial Pekin grow-out period.
