To identify the species within the genus Anaplasma circulating among ruminants in the Southwest of China, we performed the phylogenetic analysis of the 16S rRNA gene of two Anaplasma isolates from cattle and seven from goats. The two sequences obtained from cattle strains belonged to the A. marginale cluster, whereas the other seven sequences from caprine strains formed two Anaplasma spp. clusters, which diverged earlier than the clusters of A. marginale, A. centrale and A. ovis. These results indicate that there are at least two Anaplasma species circulating among ruminants in Southwestern China.
为了鉴定在中国西南部反刍动物中流行的安巴氏体属内的种，我们对从牛中分离的两个安巴氏体株和从山羊中分离的七个安巴氏体株的 16S rRNA 基因进行了系统进化分析。从牛株中获得的两个序列属于边缘安巴氏体群，而从山羊株中获得的其他七个序列形成了两个安巴氏体种群，其分化时间早于边缘安巴氏体、中央安巴氏体和绵羊安巴氏体的聚类。这些结果表明，在中国西南部的反刍动物中至少有两种安巴氏体种在流行。
