Prevalence of parasitical infestations in sheep from the Didactic Station of the University of Agricultural Sciences and Veterinary Medicine of Iaşi, during 2003-2005

Abstract

The parasitical cases were monitored in sheep from the Experimental Didactic Station of the University of Agricultural Sciences and Veterinary Medicine of Iaşi, during 2003-2005. Cestode (Thysaniezia giardi), trematodes (Dicrocoelium lanceatum), nematode (Trichostrongyloidea/Trichostrongylidae family, Dictyocaulida family; Metastrongyloidea/Protostrongylidae family) and arthropods from Arachnida classes (Acari subclass) and Insecta caused the parasitoses diagnosed in that period. Every year, psoroptic scabies has affected sheep during stable period, when the lowest temperatures of the season were reached. Grazing after the prophylactic autumn disinfection developed a trichostrongili population in the body of hosts, which was sufficient to pollute grassland and perpetuate parasitosis. The interruption of biological cycle by adult or one of the intermediary host systematic destroying has resulted in the diminution of dicroceliosis incidence
