摘要: 从龙岩市48个规模化猪场分离到28株副猪嗜血杆菌(Haemophilus parasuis,Hps),菌株经生化试验和PCR鉴定均符合Hps特征,血清学分型以4型、5型为流行菌株,以筛选出的4型LY04和5型LY05 2株代表性分离株为抗原研制Hps油乳剂灭活苗,免疫14日龄仔猪,保护率均为66.7%。

Abstract: A total of 28 Haemophilus parasuiscH.parasuis) isolates were isolated from 48 farms in Longyan. Strains were confirmed by biochemical tests and PCR. Serovar 5 was the most prevalent, followed by serovar 4. 14 days old piglets were immunized with inactivated bacterin using seorvar 4 isolate LY04 and seorvar 5 isolate LY052, respectively, which were representative strains, and the results of efficacy test showed that the protection rates were both 66.7%.

Key words: Haemophilus parasuis; isolation and identification; inactivated bacterin
