Abstract:

Objective To survey plague infection of the dogs used for food among Guangxi and Guizhou provinces in southern China and to assess the risk of infection in humans by consuming dog meat. Methods Indirect hemagglutination test(IHA) was used to measure the specific F1 antibody titer. Results During the investigation from 2012-2014, 334 serum samples of the dogs used for food and 173 serum samples of the dogs lived in the farmhouse were collect in Guangxi and Guizhou, while 226 serum samples of shepherd dogs were collect in Gansu and Qinghai for contrast. The positive serums of F1 antibody were 25.71% and 18.18% among the samples of Gansu and Qinghai respectively. All the samples were negative in Guangxi and Guizhou. Conclusion The epidemic of plague has not been found in the dogs used for food among Guangxi and Guizhou provinces in southern China. The risk to contract plague from dogs processed as food is negligible.

摘要：

目的 调查我国南方广西壮族自治区、贵州省食用犬的鼠疫感染情况,评估当地人群通过食用犬肉感染鼠疫的风险。方法 通过间接血球凝集试验检验犬只血清鼠疫F1抗体滴度。结果 2012－2014年分别在广西壮族自治区、贵州省采集当地用于食用的犬只血清334份,当地农家犬血清172份,同时在甘肃及青海省的青藏高原喜马拉雅旱獭鼠疫疫源地采集当地牧羊犬血清226份作为对照检测血清F1抗体。甘肃省犬只中25.71%为血清F1抗体阳性,青海省犬只中阳性率为18.18%,而广西壮族自治区、贵州省采集犬只全部为阴性。结论 我国南方广西壮族自治区、贵州省的食用犬只中尚未发现鼠疫感染,当地人屠宰、食用犬肉目前无感染鼠疫的风险。
