2018~2019年副鸡禽杆菌病的流行病学调查

Analysis on epidemic situation of Avibacterium paragallinarum during 2018~2019

文章旨在研究2018~2019年副鸡禽杆菌病的流行特点。2018~2019年,从山东、河北、江苏等地发病病鸡中分离副鸡禽杆菌,通过细菌分离培养、革兰氏染色、PCR分子鉴定最终获得87株副鸡禽杆菌。包括A型20株、B型57株、C型10株。副鸡禽杆菌在鸡眶下窦、气管、肺脏、卵泡上分部为主。结果表明:副鸡禽杆菌病在流行血清型上,以血清B型为主,向多种血清型共同感染的趋势发展,且一年四季均可发病,可选防控药物逐渐减少,给预防本病带来一定的困难。

The article was to study the epidemic characteristics of Avibacterium paragallinarum from 2018 to 2019. From 2018 to 2019, Avibacterium paragallinarum was isolated from diseased chickens in Shandong, Hebei, Jiangsu and other places. Through bacterial isolation culture, gram staining, and PCR molecular identification finally obtained 87 strains of Avibacterium paragallinarum. 20 strains of type A, 57 strains of type B, and 10 strains of type C were isolated. Avibacterium paragallinarum was mainly distributed in the suborbital sinus, trachea, lung and supraspinal of chickens. The results showed that the popular serotype of Avibacterium paragallinarum was mainly serotype B, and it had developed into a trend of co-infection with multiple serotypes. The illness can occur all year round, and the available drug is more and more fewer,which brings certain difficulties for the ill prevention.
