[Zoonotic trematode species identified in domestic animals from Huainan area]

To understand the zoonotic trematode species identified in domestic animals from Huainan area, Anhui Province, so as to supply the evidence for the prevention of zoonoses.

The livestock/definitive hosts were commercially available on category basis, and sacrificed for obtaining the parasitic samples via dissecting the viscera. The specimens were microscopically identified, with reference to the descriptions in the previous literature.

By identification, sorting and classification, 41 species of internal trematodes were found so far in the domestic animals fed in Huainan areas, in which 23 species were zoonotic trematodes and 18 were internally parasitic in livestock, belonging to 4 orders, 12 families and 21 genera, and occurred in 9 definitive hosts including chicken, ducks, geese, pigs, cattle, buffaloes, sheep, goats and dogs, respectively.

The findings suggest that the zoonotic trematodes belong to many kinds and prevalent in the domestic animals in Huainan areas, and such prevalence should call for high attention since it is urgent risk factors for zoonoses in this geographic area.
