Abstract

Sarcocystis is considered as a common zoonotic coccidian parasite that infects intermediate hosts orally through ingestion of contaminated graze or water with protozoa oocyte. The purpose of study is to demonstrate the incidence of Sarcocystis infection in imported cattle in Duhok abattoir and achieve the gold conventional method for muscular tissue cyst and bradyzoites detection. Muscular tissue samples have been collected from esophagus, heart and diaphragm of 150 cattle. From a total of 1350 inspected samples (diaphragm, esophagus and heart) from three different imported origin have been 94%, 92% and 41.3% samples infected respectively as well as significant differences (p <0.01) in the distribution of Sarcocystis infection among organs included and microscopic method used while no significant been found in terms of the animal origin source. Moreover, acid pepsin digestion method has shown high sensitivity in detection of Sarcocystis infection. The infection with Sarcocystis is common in imported cattle and epidemiological studies must be conducted to evaluate the country endemic with the infection.

Highlights

IntroductionThe infection by Sarcocystis characterized by cyst formation in the muscle of the intermediate host which causes muscular Sarcocystosis or intestinal Sarcocystosis when it invades the lamina propria of the final host due to the presence of marco and micro-gamonts and oocyst (Dubey et al 2015)
Sarcocystosis, as an intracellular protozoan parasitic disease, can be considered one of the zoonotic diseases that is caused by a species of parasites belonging to the phylum Apicomplexa and family Sarcocystidae (Dubey et al 2015).The infection by Sarcocystis characterized by cyst formation in the muscle of the intermediate host which causes muscular Sarcocystosis or intestinal Sarcocystosis when it invades the lamina propria of the final host due to the presence of marco and micro-gamonts and oocyst (Dubey et al 2015)
The overall incidence of Sarcocystis’ frequency of infection out of 450 samples collected from 150 imported male cattle carcasses is 76% even cyst or bradyzoite microscopically recorded

Summary

Introduction

The infection by Sarcocystis characterized by cyst formation in the muscle of the intermediate host which causes muscular Sarcocystosis or intestinal Sarcocystosis when it invades the lamina propria of the final host due to the presence of marco and micro-gamonts and oocyst (Dubey et al 2015). This coccidian parasite is considered obligatory in the relationship with carnivorous as the definitive host and non-pathogenic relationship with herbivorous or omnivorous as intermediate hosts viz. The number of the zoonotic disease transmitted from animals to humans is more than 200 diseases and they include Cysticercosis, Echinococcosis, Ascariasis, Trichinosis, and Sarcocystosis (Frenkel and Smith 2003)
