为了解贵州省规模养猪场乙型脑炎(JE)的流行情况,为该病的诊断、预防和控制提供参考,应用乳胶凝集试验(LAT)对9个地区216个规模养猪场的2 906份血清进行检测.结果表明:查出阳性血清1 239份,占受检血清的42.6％,以黔南州(74.9％)和贵阳市(66.7％)的血清阳性率较高；133个猪场检测出阳性血清,阳性场率为61.6％,以贵阳市(92.3％)和遵义市(93.5％)的猪场阳性率较高.结论:贵州省猪群存在JE感染,且感染率较高,应采取积极的防治措施.%To grasp the infected situation of swine Japanese encephalitis (JE) in Guizhou, 2 906 serum samples were collected from 216 large-scale pig farms in nine areas for detection of Japanese encephalitis virus (JEV) antibodies using latex agglutination test (LAT). The results showed that 1239 serum samples were positive, accounting for 42. 6%. The high JE infection rate (74. 9%, 66. 7%) in swine was recorded in Guiyang and Qiannan. The positive rate of large-scale pig farms was 61. 6%, and Guiyang (92. 3%)and Zunyi(93. 5%) were the highest. Therefore, swine JE infection in Guizhou was widespread, active countermeasures should be taken to prevent and cure swine JE.
