Pasteurella multocida-Associated Sinusitis in Khaki Campbell Ducks (Anas platyrhynchos)

Pasteurella multocida group B, serotype 3, was isolated from sinusitis-affected khaki Campbell ducks. To study the role of P. multocida in sinusitis, commercial khaki Campbell ducks were experimentally infected with P. multocida alone or combined with Escherichia coli.

Description
Summary:Pasteurella multocida group B, serotype 3, was isolated from sinusitis-affected khaki Campbell ducks. To study the role of P. multocida in sinusitis, commercial khaki Campbell ducks were experimentally infected with P. multocida alone or combined with Escherichia coli. In Expt. 1, experimental ducks were infected with P. multocida intranasally or ocularly. A comparison was done by intranasal inoculation with pooled nasal discharge from the affected ducks or phosphate-buffered saline. The ducks intranasally inoculated with the nasal discharge or P. multocida showed sinusitis. In Expt. 2, E. coli alone or a combination of P. multocida and E. coli was intranasally inoculated into experimental ducks. The ducks intranasally inoculated with the combination of P. multocida and E. coli had sinusitis, the same as found in the field but less severe than that of the field cases. Pasteurella multocida was already present in litter/floor of duck farms. We concluded that P. multocida played a role in induction of sinusitis. However, the sinusitis in ducks may be initiated by poor management, especially in the brooding period of ducks.Original Abstract: Sinusitis asociada con Pasterurella multocida en patos anade azulones (Anas platyrhynchos). capital sigma e aislo una Pasteurella multocida perteneciente al grupo B, serotipo 3 a partir de patos anade azulones con sinusitis. Con el fin de estudiar el papel de la P. multocida en la sinusitis, se infectaron experimentalmente patos anade azulones comerciales con P. multocida sola o en combinacion con Escherichia coli. En el experimento 1, se infectaron patos con P. multocida por via intranasal u ocular. Se realizo una comparacion mediante la inoculacion por via intranasal de una mezcla de descargas nasales obtenidas a partir de patos afectados o de una solucion salina fosfatada y amortiguada. Se observo sinutitis en los patos inoculados por via intranasal con la mezcla de descargas nasales o con P. multocida. En el experimento 2, se inocularon patos con E. coli sola o en combinacion con P. multocida por via intranasal. Los patos inoculados por la via intranasal con P. multocida en asociacion con E. coli mostraron una sinusitis similar a la observada en el campo pero menos severa. Se encontro que la P. multocida estaba presente en la cama y el piso de las granjas de patos. Se concluyo que la P. multocida desempeno un papel en la induccion de la sinusitis. Sin embargo, la sinusitis en los patos puede iniciarse por malas practi
