| Abstract | ||
| Efficiency of warfarin anticoagulant was studied against different populations of the black rat, Rattus :anus, caught from 4 districts at Sharkia govemorate (Belbies, Kafr-Sakr, Menia El-Khamh and Hehya districts) using biological method (lethal feeding periods "LFP") and biochemical technique (prothrombin time "P.T" determination). The results showed that the highest values of LFP50 and LBP9 9 were recorded with rats trapped from Hehya (3.4 and 9.9 days), while the lowest values were in case of rats trapped from Belbies (2.6 and 6.9 days). Data obtained from biochemical test were in the same trend whereas effect of warfarin (5mg/kg) on P.T. values was obviously noticed in animals caught from Belbies, while the lowest effect was observed on the animals of Hehya. Results indicated that rats trapped from Hehya showed a high tolerance to warfarin, while those caught from Belbies were relatively susceptible followed by those from Kafr-Sakr and Menia El-Khamh dis-tricts. | ||
