Abstract: Objective To detect the infection of Babesia protozoa in rodents in Chun’an county, Zhejiang province. Methods The polymerase chain reaction (PCR) was employed to detect the liver and spleen samples of 106 rodents from Chun’an county and the positive ones were sequenced, followed by phylogenetic analysis. Results It was found that there were three positive samples, 2 of which were obtained from Rattus tanezumi and one of which from R. norvegcus. The sequences of the positive samples were of high similarity with those from Babesia, with the rates of similarity being both 99% . Conclusion DNA segments of Babesia can be detected from rodents in some mountain areas of Zhejiang province, indicating that it is likely that there exists infection of rodents with Babesia in the area.
