1966年Carmichael等在美国第一次从小猎犬中分离到大种布鲁氏菌(B.canis)。嗣后,德国、巴西、墨西哥和阿根廷等近十个国家也相继报告发现B.canis感染。1984年尚德秋等从美国进口的Beagle狗和中国草狗分离到B.canis,证实国内亦存在犬种布鲁氏菌病疫区。1985～1986年我们对本地区灵川、兴安县的173只农村家狗进行B.canis感染的血清学及病原学调查,首次证实本地区存在犬种布鲁氏菌病疫源地,现报告如下。
Carmichael et al. (1966) isolated B. canis from the Beagle for the first time in the United States. Subsequently, Germany, Brazil, Mexico and Argentina and other nearly 10 countries have also reported the discovery of B. Canis infection. Isolation of B. canis from Beagle dogs and Chinese grass dogs imported from the United States in 1984, such as Suntech, confirms the presence of brucellosis in domestic dogs. From 1985 to 1986, we investigated serological and etiological investigations of B.canis infection in 173 rural domestic dogs in Lingchuan and Xing’an counties in this area. This confirms for the first time that there are foci of Brucella brucei in this area and is reported as follows .
