| Abstract | ||||
| The role of Lanisies carinatus in parasitic diseases transmissible between animal and man were studied. Their parasitic fauna of the mantel and gut were also defined. Redia & encysted metacercaria of Echinoparyphium recervatum and larvae of Angiostrogylus cantonensis were obtained from the snail tissue. Two species of Oligochaeta (Aleosoma and Naidida) and one Copepoda sp < /em>. (Harpacticoida) were found in the mantel cavity and gut. The examined L. carinatus snails were collected from 7 localities at Kafr El Sheikh Governorate, Egypt, during one year from June/96 to May/97. The identity of the larvae and cercariae recovered in L. carinatus were confirmed by bioassay in rats, ducks and fish. Albino rats were experimentally infected with the isolated A. cantonensis larvae where premature stages and mature worms were recovered 35&75 d.p.i from the brain and bronchial arteries respectively. Damage of the cerebral blood vessels, the cerebral hemisphere and medulla oblongata tissue with hemorrhages were observed in histological sections of the experimentally infected rats. Immature and mature E. recurvatum worms were recovered after 15 & 35 days from ducks infected by being fed on snail tissue containing encysted metacercariae Aleosoma sp < /em>. and Naidida sp < /em>.showing a promising value as a biological predators against Bulinus truncatus, Biomhpalaria alexandrina and Lynınaea caillaudi snails. | ||||
