禽卡氏杆菌病的研究进展

Research advances in Gallibacterium anatis disease in poultry

禽卡氏杆菌病是近年来新发现的蛋鸡的一种传染病,该病由禽卡氏杆菌引起。禽卡氏杆菌为两端钝圆的球杆菌,菌体单个散在或成对分布,能引起蛋鸡输卵管病变和腹部膨大,并使蛋鸡呈企鹅状,造成产蛋量下降,鸡只最终因输卵管囊肿、卵黄性腹膜炎、贫血、消瘦而死亡。该病可严重影响蛋鸡的健康,造成严重的经济损失。为了更好地了解禽卡氏杆菌病,文章从卡氏杆菌微生物学特性、分型、耐药性、抗四环素基因分型的决定因素、PCR和16S r DNA检测等方面进行综述,期待为该病的防治提供理论基础。

Gallibacterium anatis disease is a newly discovered infectious disease of laying hens in recent years, which is caused by Gallibacterium anatis. C, allibacterium anatis is a coccobacillus that is blunt and rounded at its two ends, and the bacterial distribution was single or in pairs. GaUibacterium anatis can cause tubal lesions and abdominal enlargement of laying hens, and make laying hens looking like penguins, resulting in the decline of egg production, while the laying hens ultimately die due to tubal cysts, vitelline peritonitis, anemia, and emaciation. The dis- ease can seriously affect the health of laying hens, causing serious economic losses. To better understand Gallibacterium anatis disease in poul- try, this article reviews the microbiological characteristics, typing, drug resistance, tetracycline resistance determinant genotyping of GaUibacterium anatis, PCR and 16 s rDNA detection, and so on, looking forward to providing theoretical basis for prevention and control of the disease.
