Prevalența dicroceliozei la ovine și caprine la ferma privată din satul Gradiște, raionul Cimișlia

Abstract

A survey incorporating field and abattoir studies was carried out on the prevalence of Dicrocoelium lanceolatum in sheep and goats in the village Gradiste, district Cimislia, the R. Moldova. Coprological studies on these animals revealed that 71,9% of sheep and 87,7% of goats were positive for dicrocoeliosis, with a mean number of eggs per gram of faeces (EPG) of 277,7 for sheep and 261,8 for goats. The necropsy liver examination of slaughtered animals revealed that 94.1% of sheep and 75% of goats were infected with D. lanceolatum and they had mean fluke burdens of 247.2 (sheep) and 298.1 (goats). No significant differences in fluke burden, liver lesion score and EPG count were observed between sheep and goats. The seasonal distribution of dicrocoeliosis indicated a higher percentage of infection in autumn and winter as compared with spring and summer. The potential role of migratory sheep and goats in the epizootiology of dicrocoeliosis is discussed.
