Evaluation of some coagulation parameters in hepatic coccidiosis experimentally induced with Eimeria stiedai in rabbits.

The objective of this study was to evaluate some coagulation parameters in hepatic coccidiosis experimentally induced with Eimeria stiedai in rabbits. Fourteen healthy New Zealand rabbits were equally divided into two groups. One group received no treatment, the other group was orally inoculated with 40 000 sporulated oocysts of E. stiedai in a 1 ml inoculum using a catheter. At day 24 after inoculation, blood samples were collected into sodium citrate-containing tubes to evaluate some coagulation parameters. Although statistically not significant, infected rabbits had prolonged prothrombin time and activated partial thromboplastin time compared with rabbits in the control group. A significant reduction (P < 0.05) was observed in the level of fibrinogen of infected rabbits compared with that of the controls. A slight decrease in thrombocyte counts of infected rabbits was not statistically significant.
