Fascioliasis is an important zoonotic disease endemic in many African countries, causing significant financial losses due to reduced productivity and visceral condemnation at slaughter. Fasciola hepatica and F. gigantica are the main causative agents of fascioliasis in domestic animals and humans. Traditional species differentiation based on their morphometric characteristics is subjective and can be challenging. This study was undertaken to identify the Fasciola species associated with cattle infection using a molecular approach. Thirty-eight Fasciola parasite samples collected from cattle slaughtered at the Sokoto modern abattoir were characterised by PCR-RFLP analysis of ITS1 and ITS2 genes using RsaI restriction enzyme, sequencing, and phylogenetic analysis. The results revealed that the isolates belonged to the F. gigantica species based on RFLPpatterns. Similarly, phylogenetic results showed clustering with F. gigantica when compared with sequences from neighbouring African countries obtained from the GenBank. This study affirmed that F. gigantica is the predominant Fasciola species affecting cattle in Sokoto state, Nigeria. The results also demonstrate the discriminatory potentials of RFLP and its ability to determine genetic variability among FasciolaParasites. [ABSTRACT FROM AUTHOR] |
