对来自日本、马来西亚和斯里兰卡的4个吉氏巴氏线虫分离物的18SrDNA序列与已发表的来自一个B的0.5kb的18SrDNA序列进行了比较。gibsoni分离物的18S rDNA序列，并与其它Babelopharus spp.距离，简约性和最大似然分析显示，几乎相同的基因型之间的小型犬巴贝来自亚洲，但出乎意料的遥远的遗传关系，从美国。而美国分离株则与B一起分离。亚洲分离株与B的亲缘关系较近。divergens和B. odocoilei。这些结果表明，来自北美和亚洲的小型巴比特犬属于不同的、遗传上亲缘关系较远的物种。
18S rDNA sequences from 4 isolates of Babesia gibsoni originating from Japan, Malaysia and Sri Lanka were compared with a previously published, 0·5 kb portion of the 18S rDNA from a B. gibsoni isolate from California, USA, and with the corresponding 18S rDNA sequences of other Babesia spp. Distance, parsimony and maximum likelihood analyses showed almost identical genotypes among the small canine Babesia from Asia, but an unexpectedly distant genetic relationship to that from the USA. While the American isolate segregated together with B. equi, the Asian isolates showed a close relationship to B. divergens and B. odocoilei. These results indicate that small Babesia of dogs originating from North America and Asia belong to different, genetically distantly related species.
