Anatomical distribution of hydatid cyst in cattle within age range (a); Fasciola hepatica (FH) co-infection status (b); within age range in animals without FH co-infection (c) and with FH co-infection (d). In a cyst anatomical distribution significantly varied among young (≤ 4 years) (χ² = 7.973, df = 2, P = 0.0186) and old animals (> 4 years) (χ² = 14.80, df = 2, P = 0.0006) and within age groups. In b a significant association was found between cyst location and FH co-infection status, where a significant difference was found in animals with FH co-infection (χ² = 22.30, df = 2, P < 0.0001), and not in animals without FH co-infection (χ² = 1.432, df = 2, P = 0.4883). c No association was found between age range and cyst location in animals absent of FH co-infection, or location within each age group. d In cattle with FH co-infection, a significant association was identified between age range and cyst location as well as among each age group. Data are presented as percentage (%) of the number of animals/ total examined cattle in the respective categories. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001.
