DNA identification of Fasciola SPP.on human and cattle in central Vietnam

Macroscopic observation of 1350 Fasciola collected from human and cattle in Binhdinh and Khanhhoa provinces identified three morphological types of the body of F.hepatica, F.gigantica and the resemblance between F.hepatica and F.gigantica. Specified Polymerase Chain Reaction (PCR) showed that they are all F.gigantica, mean that F.gigantica has high potential of morphological disguise. That all of the Fasciola detected on the cattle from Binhdinh and Khanhhoa are F.gigantica, that existence of F.hepatica population in this region maybe very low. Furthermore, a variant of Redia from F.gigantica with more Cercaria than other common types.
