Abstract

This study was undertaken to determine the prevalence of anoplocephalid cestodes in sheep and goats in Senegal. Intestines of 462 sheep and 48 goats were examined; 47.4% of sheep and 6.2% of goats were infected. The species identified and their prevalence were, among sheep, Avitellina centripunctata 38.7%, Moniezia expansa 15.4%, Stilesia globipunctata 16.7%, and Thysaniezia ovilla 0.4%. Among goats, they were M. expansa 6.2% and T. ovilla 2.1%. The prevalence of all species was not statistically different between dry and rainy seasons. The infections were single or multiple. Indeed, 56.2% of sheep were infected by a single species, 37.4% by two species, and 6.4% by three species. For goats, 66.7% were infected by M. expansa and 33.3% by both M. expansa and T. ovilla. Scanning electron microscopic (SEM) observations of tapeworms show the general diagnosis characters of these species.

Highlights

In Senegal, livestock play both social and economic roles
38.7% of sheep were infected by A. centripunctata, 15.4% by M
All except M. benedeni were found among sheep, but among goats only M. expansa and T. ovilla have been observed

Summary

Introduction

In Senegal, livestock play both social and economic roles It remains as the only source of livelihood for 30% of rural households. It is a great potential for wealth creation in the sense that it represents 4.2% of the national Gross Domestic Product and 28.8% of the primary sector (GDP) [1]. Diseases caused by parasites are factors that contribute to reduction of the productivity of these animals around the world [2]. This is a reality in sub-Saharan regions [3]. Gastrointestinal helminthes, with their toxic, mechanical, and absorptive actions, constitute a major constraint to health and productivity of domestic animals, especially in developing countries [4,5,6,7]
