* CLOPIDOL pyridine is a compound of pyridine, which has a wide range of anticoccidal action.It can be used for bird and rabbit coccidiosis. CLOPIDOL plays a major role in the stage of spore development, which can stop the development of spores in the epithelial cells for up to 60 days. It was also recently found that there was an inhibitory effect on the reproduction of the second generation, gamete reproduction and spore formation. Since chloropyridine is only inhibitory to the globule, the spore is able to grow again after withdrawal. CLOPIDOL can reduce the host's immunity to the worm.
