ABSTRACT
Toxoplasma gondii is an obligate intracellular apicomplexan parasite which is able to infect almost all warm-blooded animals. There is no information about the prevalence and genetic characterization of T. gondii in badgers (Melogale moschata) in China. Here, a total of 367 badgers were captured from different cities in Jiangxi province, Southern China. Genomic DNA was extracted from brain tissues of each badgers, and 57 (15.45%) of them were positive for T. gondii by semi-nested PCR of the B1 gene. The positive DNA samples were typed at 11 genetic markers, including 10 nuclear loci (SAG1, 5'-SAG2 and 3'-SAG2, alternative SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1) and an apicoplast locus (Apico), with multilocus polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technology. Among them, 4 were completely typed at all loci, and 2 was genotyped for 9 loci, showing that they belong to ToxoDB#9. This is the first report of prevalence and genetic characterization of T. gondii isolates from badgers in China, which contributes to broader understanding of population structure of T. gondii in China. It is important for the prevention and control of T. gondii infection in wild animals.
