Abstract

Previous studies show heamotropic Mycoplasma infection frequently occurs among splenectomized, immuno-suppressive or co-infected dog populations. However, in our study, the detection of 162 blood samples from dogs found 3 healthy, female dogs infected with Mycoplasma haemocanis in southeastern China. These infected dogs were grown in dog breeding center and had a history of tick infestation. This is the first molecular report of M. haemocanis in dogs from China. The 16S rRNA gene was partially sequenced and a phylogenetic tree constructed. Mycoplasma spp. was 99.9%-100% identical to the corresponding gene sequences of M. haemocanis and M. haemofelis available in GenBank. In this study, Mycoplasma spp. was identified as M. haemocanis because the bacterium was obtained from dogs.

摘要

先前的研究表明，血支原体感染常见于脾切除、免疫抑制或合并感染的犬类群体中。然而，在我们的研究中，对来自中国东南部的162份犬血样进行检测时，发现3只健康雌性犬感染了犬血支原体。这些感染犬饲养于犬繁育中心，并有蜱虫寄生史。这是中国犬类感染犬血支原体的首例分子报告。对16S rRNA基因进行了部分测序并构建了系统发育树。支原体属与GenBank中犬血支原体和猫血支原体的相应基因序列具有99.9%-100%的同源性。在本研究中，由于该细菌是从犬类中分离得到的，因此支原体属被鉴定为犬血支原体。
