    Abstract:
    The effect of chronic Fasciola hepatica infection on the activity of plasma aspartate aminotransferase (AST), glutamate dehydrogenase (GLDH) and gamma-glutamyl transpeptidase (GGT) was investigated in water buffaloes dosed daily with 60 F. hepatica metacercariae over 20 days. Experimental fluke infection caused no clinical signs but provoked an increase in plasma level of IgG directed against F. hepatica from 4 weeks after infection. There was a significant increase in plasma AST from 6 weeks post-infection. Maximal values were reached at 14 weeks and remained significantly elevated by 23 weeks. Plasma GLDH was significantly elevated from 6 to 21 weeks post-infection. Significant increases in plasma GGT occurred from 8 to 26 weeks post-infection, reaching maximal values at 15 weeks. This study shows that plasma enzyme activities may be useful in studies of fluke-induced liver damage in water buffaloes.
