The AST/ALT ratio was estimated in 182 dogs infected with Babesia canis. Among these dogs 65 had anaemia and 68 were azotaemic. Student’s t test was used to compare means of the AST/ALT ratio in anaemic and non-anaemic dogs, and in azotaemic and non-azotaemic dogs (p < 0.05). The differences in AST/ALT ratio between anaemic (1.52 ± 1.15) and non-anaemic (1.76 ± 1.34) dogs were statistically insignificant (p = 0.23), however, the comparison of AST/ALT ratio between azotaemic (2.68 ± 1.52) and non-azotaemic (1.08 ± 0.53) dogs revealed a significantly higher value of this index in azotaemic dogs (p = 0.00). The present results suggest that kidney injury contributed to increased AST activity in these dogs.

The liver fluke Fasciola hepatica infects a wide range of hosts, and has a considerable impact on the agriculture industry, mainly through infections of sheep and cattle. Further, human infection is now considered of public health importance and is hyperendemic in some regions. The fluke infection causes considerable damage to the hosts’ liver. However, the mechanisms of liver destruction have not yet been completely elucidated. In the present report we incubated a human liver cell line in the presence of either F. hepatica excretory/secretory material (FhES) or recombinant phosphoglycerate kinase (FhPGK). Dosedependent cytotoxicity in the presence of FhES was observed, indicating that FhES is capable of killing human hepatocytes, supporting a role for FhES in damaging host liver cells during infection; while treatment with a recombinant intracellular protein — FhPGK, had no impact on cell survival.

Not only do males and females of many species vary in their responses to certain parasitic infections, but also to treatments such as vaccines. However, there are very few studies investigating differences among sexes following vaccination and infection. Here we demonstrate that female Sprague-Dawley rats vaccinated with cDNA encoding a recently discovered cysteine proteinase of Fasciola hepatica (FhPcW1) develop considerably lower liver fluke burdens after F. hepatica infection than their male counterparts. This is accompanied by differences in the course of their immune responses which involve different eosinophil and monocyte responses throughout the study as well as humoral responses. It is evident that host gender influences the outcome of parasitic infections after vaccination and research on both sexes should be considered when developing new treatments against parasites.
