Neospora caninum is an intracellular protozoan that infects many domestic and wild animals. Domestic dogs and other canids function as definitive hosts, while other mammals serve as natural intermediate hosts. In the present study, the brain tissues of bats collected in Yunnan Province, Southern China were tested by N. caninum specific-nested PCR, targeting the Nc-5 gene and the internal transcribed spacer 1 (ITS1) region of the ribosomal DNA to determine whether bats could be infected with N. caninum. N. caninum DNA was detected in 1.8% (4/227) of bats, i.e., 1.7% (1/60) in Rousettus leschenaultia, 1.7% (1/58) in Hipposideros pomona, 2.9% (2/69) in Rhinolophus pusillus, and none (0/40) in Myotis daubentoniid. The findings of the present study are only the first indication that bats could serve as an intermediate host, and further studies are necessary to confirm whether bats are involved in the transmission of N. caninum infections.
