PREVALENCE OF COCCIDIA AND INTESTINAL HELMINTH - PARASITES IN SHEEP IN SOME DISTRICTS –LIBYA

Abstract

Study was done on total 250 sheeps were examined from five districts in Libya, to determine the rate of gastrointestinal parasites infecting sheeps. Based on the results of this study, nematodes , Emeria and Monizia expansa were the most commonly identified internal parasites of sheeps. About 85.6% of the sheeps were infected with gastrointestinal parasites in five districts About 32.8% of the sheeps were infected with Strongyle eggs, the total infection rate of Nematodirus eggs was 8% in five districts while Monizia expansa was 13.2%. The faecal examination and postmortem showed Six genera of nematode were identified such as Haemonchus contortus, Trichuris globulosa, Nematodirus spp., Trichostrongylus colubriform., Trichostrongylus vitrinus, Marshallagia marshalli, and Strongyloides papillosus. The percent parasites loads were higher in sheeps more than one year old, there was significant effect between the age classes and fecal egg loads . While the five districts had higher Eimeriainfections with 74.8%, show higher oocyst loads in five districts The main species of Eimeria identified were E. aspheronica (33.7%), and E.minasensis (23.5%) were the most prevalent species. Other species present were E. caprina (13.9%), E. christenseni (3.6%), E. hirci (6.6%), E. arloingi (14.4%).
