Prevalence of Internal parasites of sheep In Khartoum State in summer

Abstract

This study was focused on the prevalence of GIT parasites that infect sheep in Khartoum State and influence of breed, locality, age, sex, and body condition on infection rate. Eighty five faecal samples were collected from sheep from three different localities in Khartoum State. These include Elmowelih (Omdurman), Bahri Livestock market (Bahri) and Wester Soba Project (Khartoum). 64sheep were found to be infected with an overall prevalence of 75.2%.Eimeria spp oocysts were the most common(75.2%) followed by Haemonchusspp(9.4%) and Moneiziaexpansa(2.3%). Infestation with one species of parasite per animal was the commonest )63.5%( while, mixed infection was the least encountered )11.7%(. Khartoum locality was highly infected with Eimeriaspp. (80%) followed by Omdurman (76.6%) and Bahari (70%). No record concerning Haemonchus was observed at Khartoum locality. While, Omdurman and Bahri showed the same record )13.3%(. Moneizia expansa was found only at Khartoum locality with record of 8%. According to the breed, Zagawa ecotype showed the highest prevalence of Eimeria spp. (100%), followed by Baladi )84.6%(, Hamari )78.9%( while the lowest prevalence )67.5%( and )50%( were recorded in Kabbashi and Shukri respectively. The highest prevalence of Haemonchusspp was demonstrated in Zagawa ecotype (22.2%) followed by (10.5%) and (10%) in Hamary and Kabbashi, respectively. There is no record of Haemonchus in Baladi and Shukri ecotypes. Moneiziaexpansawas only occurred in the Baladi with prevalence rate of )15.3%(. Infection with Eimeria spp. was more prevalent in young sheep (80.4%) compared with(69.2%) in the adults. MeanwhileHaemonchus in adult sheep showed prevalence rate of 12.8% compared with (6.5%) in the young.Moneizia expansa was found only in young withprevalence rate of 4.3%. Sex wise prevalence of Eimeria spp was (78.2%) and (71.7%) in males and females, respectively. Moreover, regarding Haemonchus was (10.8%) and (7.6%), respectively.Moneizia expansa was relatively same in male and female with prevalence rate(2.1%),( 2.5%) respectively. No significant association was found between Eimeria sppand Moneizia expansa prevalence and body condition. But considering Haemonchus, animals in poor body condition showed infection rate of )19.1%( compared with )6.25%( in animal with good body condition. Nine species of Eimeria were detected in this studyon the basis of theirmorphological characteristic. These are E. ovina,E.ovinoidalis , E. pallida, E. parva, E. faurei, E. ahsata, E. crandalis, E. intricata and E. granulose
