Although bats were considered as a major host of trypanosomatid flagellates, information of trypanosomes in bats is unknown in China. We collected bats in 2015 from Shandong Province of China and used PCR to amplify the Trypanosoma glycosomal glyceraldehyde phosphate dehydrogenase (gGAPDH) gene and 18S rRNA gene from the bat blood samples and heart tissues. The results showed that 10.3% (13/126) of bats (Eptesicus serotinus and Myotis pequinius) were positive for trypanosomatid DNA and DNA sequencing showed that all PCR amplified Trypanosoma DNA belonged to T. dionisii. We concluded that T. dionisii had a infection rate in bats from China. For the first time, Trypanosoma infections were detected in bats from China, providing valuable information on the prevalence of these parasites in Asia. This is also the first report of Trypanosoma dionisii in Myotis pequinius, suggesting that Trypanosoma dionisii has a broad host species.
