Efficacy of garlic extract on hepatic coccidiosis in infected rabbits (Oryctolagus cuniculus): histological and biochemical studies.
The rabbits were divided into three groups, of 12 rabbits each. G1 was the (non-infected non-treated) as control, G2 was the (infected-non treated), and G3 was the (infected and treated) rabbits. Each rabbit in the infected groups were given (10(3)) sporuleted oocysts of Eimeria stiedae per rabbit after forty five days exactly. Faecal sample of rabbits from each group were examined each day post infection till oocysts appeared in faeces. The treatment was given by using suitable dosage of garlic according to body weight. After 15, 21, 28, & 35 days post-treatment faecal oocysts were output. Biochemical parameters as serum liver function (ALT, AST, GGT & ALP) that denoted the he-patic cells injury. The results showed a significant differences in the mean values of oocysts shedding and their mean number in bile ducts between Gs 2 &3 from the 15th day post infection (PI) (mean +/-SD:40.33 +/- 16.72 & 25.17 +/- .56 respectively) till the experimental end on the 35th day (55.75 +/- 19.79 & 0.94 +/- 1.43 respectively). The histopathological alterations were in liver of G2 at the experimental end. Coccidiosis in G2 induced histopathological alterations in liver tissue, marked cytoplasmic vacuolations in hepatocytes with clear signs of karyolysis, and dilatation of sinusoids with increase in Kupffer cells. Leukocytic infiltration around congested blood vessels was noticed. Efficacy of garlic on E. stiedae in infected Gs was resident. The liver of G3 regained almost normal appearance compared to control.
