为了解副猪嗜血杆菌(Haemophilus parasuis,Hps)在广东省的流行情况,采用细菌分离鉴定和PCR方法对广东省79家规模化猪场的227头疑似关节炎、多发性浆膜炎的发病猪进行了检测。结果显示,副猪嗜血杆菌阳性率达22.74%。对猪场全年发病情况进行数据统计分析,发现1~3月Hps阳性率最高。使用间接血凝试验方法对55株临床分离株进行血清学分型,结果显示5型(23.68%)最为流行,其次是12型(13.16%)和4型(10.53%)。
In order to understand the epidemic situation of Haemophilus parasuis (Hps) in Guangdong Province, bacterial susceptibility and susceptibility of 227 cases of suspected arthritis and multiple serositis in 79 large-scale swine farms in Guangdong Province were analyzed by bacterial isolation and PCR Pigs were tested. The results showed that Haemophilus parasuis positive rate of 22.74%. Statistical analysis of the incidence of pig farms throughout the year, found 1 to 3 months the highest positive rate of Hps. Serological typing of 55 clinical isolates was performed using the indirect hemagglutination test. Type 5 (23.68%) was most prevalent, followed by type 12 (13.16%) and type 4 (10.53%).
