广州及其周边地区马梨形虫病血清流行病学调查

Seroepidemiological Investigation of Equine Piroplasmosis in Specific Equine Disease-free in Guangzhou area

为广东从化无规定马属动物疫病区建设的顺利进行和了解周边地区马属动物马梨形虫病的存在情况,采用酶联免疫吸附试验(ELISA)和涂片镜检的方法对广州、东莞和深圳的马属动物进行了马梨形虫病(马巴贝斯虫和驽巴贝斯虫两种虫体)的流行病学调查。结果表明,上述三个地区的马属动物均存在不同程度的马梨形虫病两种虫体的抗体,且出现同一个马场和在同一匹马同时存在两种虫体抗体的情况。对所有抗体阳性马匹进行涂片镜检未发现虫体,也未发现有马梨形虫病临床症状的马属动物。

In order to found the Specific disease-free Zone for hosting the horse racing during Guangzhou Asian Game, an investigation for the sero prevalence of Equine Piroplasmosis （EP） in this objective area and the adjacent domains （Dongguan and Shenzhen city） in Guangdong province was conducted. An ELISA and the smear microscopy methods were used. The results showed that there were some positive detection rates of antibodies specific to Theileria equi and/or Babesia caballi respectively in Guangzhou, Dongguan and Shenzhen. However, these seropositive racings had no any clinical findings, and no parasites were found by the blood smear microscopy.
