Gastrointestinal Nematode Parasites of Small Ruminants and Anthelmintics Efficacy Test in Sheep of Haramaya District, Eastern Ethiopia

Abstract

Abstract:The combination of cross-section and controlled field trail were carried out from December 2015 to June 2016 at Haramaya District, Eastern Hararhge, Ethiopia to evaluate the prevalence ofgastrointestinal nematodes and anthelmintic efficacy test in naturally infected small ruminants using faecal egg count reduction (FECR) test. From a total of 372 faecal samples examined using fecal flotation technique about 57% (212/372) samples were positive to gastrointestinal nematodes. Coprological investigation revealed that sheep and goats in district were infested with varieties of nematode parasites. The strongyles species were highly prevalent nematode parasites identified at about 22.3% (83/372) followed by trichuris 9.1% (34/372) and strongyloides 5.6% (21/372); whereas mixed infections of strongyles and strongyloides were recovered at lowest rate which accounted for about 5.1% (19/372). From considered risk factors age and kebele showed significant association (p<0.05) with prevalence of nematodes parasites. The study revealed that 53.29% (97/182) of goats and 60.53% (115/190) sheep were found positive, while 58% (115/198) in female and 55.74% (97/174) in male and showed no significant difference (p>0.05) between these factors. Mc Master egg counting in sheep harbored nematode parasites showed relatively similar percentage with no significant difference; but more of examined animals were classified in the range of moderate to heavy infections. The faecal egg count reduction test against albendazole, Tetraclozash and ivermectin indicated that 97.59%, 98.79% and 99.56% respectively which indicated an overall of very good state of efficacy against gastrointestinal nematodes of sheep. Therefore this study revealed that small ruminants of the study area harbored considerable level of gastrointestinal nematodes parasites which need further studies on species identification, larval ecology and strategic deworming with proper practice of available anthelmintics in small ruminants of the study area.

Prevalence of Gastrointestinal Helminthes among Goats in and around Ranchi, Jharkhand, India

“…This higher prevalence of gastrointestinal helminths is in accordance with other workers in India (Velusamy et al, 2015;Molla and Bandyopadhyay, 2016;Sanalkumar, 2017 andJena et al, 2018) and abroad (Raza et al, 2014;Yeasmin et al, 2015, Ahmed et al, 2017and Dabasa et al, 2017, in different climatic conditions. Nematodes were recorded to be of highest prevalence (62.37%) followed by trematodes (56.02%) and cestodes (47.63%) (Table 1 and Figure 1).…”

“…Out of 930 samples collected and examined from goats in and around Ranchi, 801 were recorded to be positive for gastrointestinal helminths (Table 1and Figure 1) (Shan and Chaudhry, 1995;Sanyal, 1998 andAhmed et al, 2017). This higher prevalence of gastrointestinal helminths is in accordance with other workers in India (Velusamy et al, 2015;Molla and Bandyopadhyay, 2016;Sanalkumar, 2017 andJena et al, 2018) and abroad (Raza et al, 2014;Yeasmin et al, 2015, Ahmed et al, 2017and Dabasa et al, 2017, in different climatic conditions.…”

Quality of albendazole tablets legally circulating in the pharmaceutical market of Addis Ababa, Ethiopia: physicochemical evaluation

“…Several studies have been conducted on the efficacy of albendazole using in vivo or in vitro techniques in Ethiopia and reported good or low efficacy [1, 3, 12] . The low efficacy reports may be related either to the development of drug resistance by parasites or the quality of the preparation.…”

“…Small ruminant production have been played significant role in economies through the provision of meat, milk, household income, manure and skin in addition to contribute a larger proportion of readily available meat in the diets of pastoralists [1]. Majority of the small ruminants reared in arid and semi-arid areas of Ethiopia are kept by smallholder farmers.…”

“…Majority of the small ruminants reared in arid and semi-arid areas of Ethiopia are kept by smallholder farmers. Small ruminants in these areas, particularly in southern Ethiopia where pastoral community dominates, are threatened by environmental factors such as erratic rainfall, intermittent droughts and diseases [1]. Such environmental factors put pressure on livelihood of pastoralists and agropastoralists.…”
