PREVLENCE AND RISK FACTORS FOR OPISTHORCHIS VIVERRINI INFECTION AMONG CATS AND DOGS IN SIX DISTRICTS SURROUNDING THE UBOLRATANA DAM, AN ENDEMIC AREA FOR HUMAN OPISTHORCHIASIS IN NORTHEASTERN THAILAND.

Opisthorchis viverrini is a zoonotic liver fluke that causes opisthorchiasis among humans in endemic areas, such as northeastern Thailand. The objective of this study was to determine the prevalence and risk factors for O. viverrini infection among cats and dogs in six districts surrounding Ubolratana Dam.
