Concomitant occurrence of oxidative stress and hydatid cyst in sheep, goat and cow naturally infected

Abstract

This study was conducted aiming at knowing the pathological changes that are concomitant with natural infection ofhydatidosis in sheep, goat and cattle, in addition to estimate, if infection has relations with oxidative stress via estimation of thetotal antioxidants and oxidants in hydatid fluid. Results of the present study elucidate the presence of chronic histopathologicallesions represented by hemorrhage and vascular changes, hepatic programmed cell death, portal fibrosis, infiltration ofinflammatory cells around hydatid cysts in addition to necrosis, collection of hydatid fluid from 25 samples (each one) forestimation of total Antioxidants and total oxidants in hydatid fluid. Results showed total antioxidants level in fertile cystshigher than in sterile cysts, and there was no significant variation in total oxidants of fertile and sterile cysts.
