A cross-sectional survey on bovine fasciolosis was conducted in the Binh Dinh province of Central Vietnam that was previously identified as hyperendemic for human fasciolosis. In Vietnam, both pure Fasciola gigantica and hybrid and/or introgressed populations of liverflukes bearing genetic material from both Fasciola hepatica and F. gigantica infect humans and animals. In this study, 825 cattle were randomly selected from 8 of the 11 provincial districts for faecal collection; blood samples were taken from 400 of these animals. Fasciola eggs and antibodies against Fasciola were detected by a quantitative sedimentation method and an Enzyme Linked Immunosorbent Assay, respectively. Overall, 54.9% of the animals were shedding Fasciola eggs while 72.2% were Fasciola seropositive. Animals under two years showed lower Fasciola infection rates than older animals. There were no differences in infection rates between districts. These results indicate a very high prevalence of Fasciola infections in cattle in Binh Dinh province. It is concluded that a fasciolosis control programme should be designed in this region aiming at reducing infection in both cattle and humans. (C) 2010 Elsevier B.V. All rights reserved.
