【摘要】：为了解近年来四川主要养猪地区猪群猪2型链球菌(S.suis 2)的流行情况,本研究利用ELISA抗体检测试剂盒对来自四川地区15个市(区)526份猪血清样品进行S.suis 2血清流行病学调查。四川地区猪群血清调查的总阳性检出率为40.30%(212/526);按地区分析,15个市(区)S.suis 2检出阳性率的地区占86.67%(13/15),其中阳性检出率超过50%地区占46.67%(7/15),宜宾地区的阳性检出率高达78.57%(11/14);按猪场分析,四川地区猪场S.suis 2阳性检出率高达76.74%(33/43),其中规模化猪场阳性检出率较高,为81.81%(18/22);在母猪、保育猪和育肥猪的猪群血清中,种母猪阳性检出率最高,为76.28%(74/97);并且夏季的阳性检出率最高,为46.81%(110/235)。研究表明S.suis 2在四川主要养猪地区普遍存在,并且在部分养猪区域、规模化猪场及种母猪猪群中存在较大的流行风险。本研究对四川主要养猪地区S.suis 2的流行和预防提供了调查依据。
[Abstract]:In order to understand the epidemic situation of S.suis 2 in swine herd in Sichuan province in recent years, the seroepidemiology of S.suis 2 in 526 pig serum samples from 15 cities (districts) in Sichuan was investigated by Elisa antibody detection kit. The positive rate of S.suis 2 was 86.67% (13 / 15) in 15 cities (regions), of which 46.67% (7/ 15) were positive in more than 50% areas and 78.57% (11 / 14) in Yibin area, respectively, according to the analysis of pig farms, the total positive rate of serological investigation was 40.30% (212 / 526), and the positive rate of S.suis 2 was 86.67% (13 / 15) in 15 cities (regions), among which 46.67% (715 / 15) were positive in more than 50% areas and 78.57% (11 / 14) in Yibin area. The positive rate of S.suis 2 in Sichuan pig farm was 76.74% (33 / 43), among which the positive rate in large-scale pig farm was 81.81% (18 / 22). Among sows, the positive rate of sows was the highest, 76.28% (74 / 97) in sows, and the highest in summer. It was 46.81% (110 / 235). The results showed that S. suis 2 was prevalent in the main pig breeding areas in Sichuan Province, and there was a large epidemic risk in some pig breeding areas, large scale pig farms and sows. This study provided the basis for the investigation and prevention of S.suis 2 epidemic in the main pig raising areas in Sichuan province.
