中文摘要：

为了解天津部分猪场副猪嗜血杆菌病（HPs）和猪传染性胸膜肺炎（PCP）的流行情况,利用间接血凝试验对采自9个规模猪场的178份猪血清样品进行副猪嗜血杆菌抗体检测,对采自8个规模猪场的166份猪血清样品进行猪传染性胸膜肺炎放线杆菌抗体检测。结果表明：副猪嗜血杆菌阳性率为18.54%（33/178）,其中断奶仔猪和保育阶段猪阳性率为23.58%（25/106）;猪传染性胸膜肺炎的阳性率为21.08%（35/166）,其中断奶仔猪阳性率为20.93%（9/43）,育肥猪阳性率为27.66%（13/47）,种猪阳性率为21.62%（8/37）。说明天津地区部分猪场的副猪嗜血杆菌病和猪传染性胸膜肺炎呈地方性流行。

英文摘要：

To investigate the prevalence status of Haemophilus parasuis （HPs） and porcine contagious pleuropneumonia （PCP） in partial pig farms of Tianjin, 178 serum samples collected from 9 different scale pig farms were used for the detection of antibodies against HPs and 166 ser- um samples from 8 different scale pig farms were used for the detection of antibodies against porcine actinobacillus pleuropneumoniae （APP） u- sing an indirect hemagglutination test, respectively. The results showed that the positive rate of HPs was 18.54% （33/178）, of which the posi- tive rate was 23.58% （25/106） in weaning piglets and nursing pigs. The positive rate of PCP was 21.08% （35/166）, among which the posi- tive rate was 20.93% （9/43） in weaning piglets, and was 27.66% （ 13/47 ） in fattening pigs, and was 21.62% （ 8/37 ） in sows. The results indicate that HPs and PCP in partial pig farms of Tianjin are endemic.
