Epidémiologie et manifestations clinicopathologiques de la maladie de Newcastle chez des poulets de race locale nigérians

Abstract

Une étude rétrospective a été menée sur la maladie de Newcastle (MN) diagnostiquée chez des poulets de race locale dans le service ambulatoire aviaire du Veterinary Teaching Hospital, à l’université d’Ahmadu Bello, Zaria, Nigeria, entre janvier 1978 et décembre 1997. Sur un total de 280 cas, le taux d’incidence de la MN a été plus élevé pendant la saison sèche avec 183 cas (68,4 p. 100) que pendant la saison des pluies avec 97 cas (34,6 p. 100). Les résultats ont suggéré que le taux de la MN était plus élevé pendant la saison sèche peut-être en raison de l’harmattan, de la force du vent, du froid et du stress. Le taux a été plus élevé chez les jeunes avec 58 cas (20,7 p. 100) contre 34 (12,1 p. 100) chez l’adulte. La différence entre les cas de MN pendant la saison sèche et pendant la saison des pluies a été significative (p < 0,05). La forme de Doyle de la MN a été la forme qui a eu la plus grande incidence avec 106 cas, contre 36 cas pour celle de Beach, 6 cas pour celle de Beaudette et aucun cas pour celle de Hitchner. Ainsi, il est recommandé d’utiliser des antigènes qui peuvent stimuler la production d’une forte réponse des anticorps contre la forme virulente de Doyle, lors de la production de vaccins contre la MN.
