This study showed that, the cyst of P. cervi are about 0.23 mm in diameter and are e1sily discernible with the naked eye as round black spots. Cattle and sheep become infected with P.cervi by swallowing these cysts, the stock ingest them under field conditions when drinking or when feeding on vegetation carrying cysts in localities where infected Bulinus (snail) occur. In their turn the snails become infected with the larval stages of P. cervi by miracidia which hatch from eggs passed in faeces of infected cattle.enhttp://creativecommons.org/licenses/by/3.0/Journal ContributionStomachParamphistomum cervi
