STUDIES ON THE BIOLOGY OF PARAMPHISTOMUM CERVI SCHRANK, 1790IN SHEEP IN THE DISTRICT OF ESKİŞEHİR ÇİFTELERSTATE FARM
Abstract
From the infected farm pastum 4068 Planorhis planorbis,
2041 Valvata macrostoma, 1471 Aplexa hypnorum, 167 Lymnaea truncatula,
17 Planorbis carinatus, 6 Lymnaea auricularia and i Succinea pftifferi were
cotlected and controlled for the natural P.cervi infection.
Only 64 out of 4068 P.planorbis (i. 57 %) were found infected with the
larval stages of P.cervi. From April to November 1977, natural infectd P.
planorbis were found every month with the maximum inftction in October (2.20
%).
P.cervi eggs were obtained from sheep at necropsy, in the Çifteler State
Farm. Six different snail species with the exception of S.pfeifferi were exposed
to P.cervi miracidia cultured in the laboratory.
Among the snail species only P.planorbis were found sıısceptible to P.cervi
infection. No development has occurred in the other snails.
The infection rates were found related with the number of miracidia and
the size of the snails. Difftrent d.welopment stages of P.cervi in P.planorbis were
investigated.
Fifteen lambs were inftcted with 1000 P.cervi metacercariae. The inftetion rate in these animals wasfound to be between 19.6-77.0 %. The prepatent period was found 102-142 days in the infected animals.
