从海南省人血清中检出甲属虫媒病毒HYM_1抗体

THE SEROEPIDEMIOLOGICAL INVESTIGATION OF AN ALPHAVIRUS STRAIN IN HUMAN SERA FROM HAINAN PROVINCE

１９９５ 年， 从海南省立才蚊虫标本中分离到１ 株病毒， 编号为 Ｈ Ｙ Ｍ１ 。经理化、生物学性状及血清学鉴定表明 Ｈ Ｙ Ｍ１ 与 Ｍ Ａ Ｙ 病毒抗原性相近。应用间接免疫荧光法对海南省部分地区人血清标本共４２６ 份， 进行了抗体检测。其中当地人血清标本２２６ 份， 阳性１７ 份， 阳性率为７０８ ％ 。驻海南省部队人血清标本２００ 份， 阳性１ 份， 阳性率为０５ ％ 。

In 1995,a virus strain,HYM 1,was isolated from mosquitoes multiplying in Licai farm of Hainan province.It was identified to be similar antigenicity to Mayaro virus(MAY) of Alphaviridae by the physical,biological and serologic properties.HYM 1's antibody was detected in 426 human sera collected in Hainan by immune fluorescene assay(IFA).Among the 226 local people's sera,16 were positive,the positive rate was 7 08%,while,out of the 200 sera of the garrison there,only one positive serum was detected,the positive rate was 0 5%.
