Enzymatic activities of markers of liver damage in serum samples. (a) Alanine aminotransferase (ALT), (b) alkaline phosphatase (ALP), (c) γ-glutamyl transpeptidase (γ-GTP). Intact group (white bars) and infected with trophozoites during 12 h (checkered bars) and 48 h (black bars). Each bar represents the mean value ± SE, n = 5 tested by duplicated assays. a: mean values significantly different from the intact group, p < 0.05; b: mean values significantly different from the sham group at 12 h, p < 0.05; c: mean values significantly different from the sham group at 48 h, p < 0.05.
