The isolation and identification of Avibacterium paragallinarum serovar B-1 from severe infectious coryza outbreaks in broiler breeders in Panama is reported for the first time. Infectious coryza was absent for over a decade in the breeder farms area. Disease outbreaks were characterized by an up to 45% drop in egg production and increased mortality. Use of a commercial trivalent bacterin and a strengthened biosecurity program prevented outbreaks in susceptible flocks in the farm.
首次报道了从巴拿马肉种鸡严重传染性鼻炎疫情中分离并鉴定出副鸡禽杆菌B-1血清型。在种鸡场地区，传染性鼻炎已绝迹十多年。疾病暴发的特征是产蛋量下降高达45%，死亡率增加。使用商业三价菌苗和加强生物安全计划预防了农场易感鸡群的疫情暴发。
