Abstract

The aim of our study was the determination of prevalence of the sarcosporidiosis in the bovine carcasses in the slaughterhouses of El Harrach and the identification of involved species of Sarcocystis. Samples of oesophagi and diaphragms of 200 cattles brought down in the slaughterhouse of El Harrach were analyzed by the histo-pathological technique and the technique of digestion pepsique. We did not note macroscopic cyst in the carcasses inspection. The enzymatic digestion and the histo-pathological analysis revealed high rates of infestations (95%) and (80%) respectively. Cysts with thin wall of S. cruzi were dominant in diaphragms (94.2%) and in oesophagi (100%). A low rate of cysts with thick wall was detected in diaphragms (4.4%) and a rate of 0% in oesophagi. A single cyst of S. hominis was able to be diagnosed by photonique microscope in a diaphragm.

Highlights

In Algeria, our cattle herd is very frequently affected by many muscular protozoan (Toxoplasma gondii, Neospora caninum and Sarcocystis sp.)
A study on bovine sarcosporidiosis was conducted at slaughterhouses in the north of Algeria, in particular those of El Harrach
On the 200 cattle that we have inspected at slaughterhouses of El Harrach, we did not find macroscopic cyst in the diaphragm or in the oesophagi

Summary

Introduction

In Algeria, our cattle herd is very frequently affected by many muscular protozoan (Toxoplasma gondii, Neospora caninum and Sarcocystis sp.). The National Institute of the Veterinary (Ministry of Agriculture and the Algerian rural development) revealed during inquiries at national level, high prevalence of toxoplasmosis and bovine neosporose. For the sarcosporidiosis, it is less frequent in our slaughterhouses. Some studies on prevalence of the sarcosporidiosis were carried out, in particular those of Nedjari et al [1] and of Harhoura et al [2] who reported a very high prevalence at slaughterhouses of Hussein Dey and Rouiba respectively. A study on bovine sarcosporidiosis was conducted at slaughterhouses in the north of Algeria, in particular those of El Harrach. The study included 200 cattle slaughtered to determine the prevalence of sarcosporidiosis by two diagnostic techniques, enzyme digestion and histopathological study
