The Evaluation of Immune Response to Parasitic Agents in Sheep

Abstract

The study was been performed to emphasizing the dynamics of immunological parameters in healthy and parasitically infested youth sheep from different private herds from Timiş district. The researches were been made on 20 youth sheep 10-11 months aged from Ţurcana breed divided in two groups: first group (M) comprised 10 healthy sheep periodic treated with antiparasitic drugs and the second group (E) contained 10 sheep who never received any antiparasitic drugs. All animals are clinical healthy, but those of E group are more skinny and have long and bristled fleece. From both groups were been taken blood samples in the view of evaluation the dynamics of unspecific immune response, represented by some parameters, like seric properdine, seric lysozime, phagocytic index and leucogramme. The obtained results confirm that immune system in infected animals always tried to counteract the noxious action of parasitic agents through increased values of studied parameters. A coproscopic examination of both studied groups identified first instar larvae of Dictyocaulus filaria and Trichostrongylus spp. in E group.
