Abstract

Introduction: Gastrointestinal tract nematodes are considered to be the most significant and underestimated problems that hinder sheep productivity.

Objective: This study aimed to evaluate the epidemiology of gastrointestinal tract nematode infestation of sheep in the Toke Kutaye District of West Shoa Zone, Ethiopia.

Methods: A cross-sectional study was conducted to determine the prevalence and risk factors associated with gastrointestinal tract nematode parasite infestation in sheep. Faecal samples were collected from 384 sheep and subjected to coprological examination, including direct smear, flotation techniques, and Baermann techniques for screening and identifying gastrointestinal nematodes.

Results: The overall prevalence of gastrointestinal tract nematode parasite infestation in sheep in the study area was 284 (73.96%). From the total positive cases, males and females were 97 (82.91%) and 187 (70.04%), respectively. The predominantly detected gastrointestinal tract nematodes of sheep in the study area were Trichostrongylus 111 (28.91%), Oestartagia 55 (14.32%), Haemonchus 42 (10.94%), Oesophagostomum 48 (12.50%), and Trichuris 23 (5.99%). Mixed nematode eggs were noticed in some of the sheep beside the single type of nematode eggs, with a prevalence of 85 (22.14%). The relationship in the occurrence of parasites between sex, age groups, body conditions, and seasons was statistically significant (P = 0.008, P = 0.014, P = 0.001 and P = 0.003), respectively.

Conclusion: The present study is of great importance to add to the existing knowledge of the epidemiology of gastrointestinal tract nematodes of sheep, and the findings are very important to apply the proper control and prevention strategies for gastrointestinal tract nematodes of sheep in the area.

埃塞俄比亚西Shoa区Toke Kutaye绵羊胃肠道线虫寄生虫流行病学评估。
引言:胃肠道线虫被认为是阻碍绵羊生产力的最重要和被低估的问题。目的:本研究旨在评估埃塞俄比亚西Shoa区Toke Kutaye区绵羊胃肠道线虫感染的流行病学。方法:进行横断面研究,以确定绵羊胃肠道寄生虫感染的流行率和相关危险因素。从384只绵羊身上采集粪便样本,并进行粪检,包括直接涂片、浮选技术和筛选和鉴定胃肠道线虫的Baermann技术。结果:研究区绵羊胃肠道线虫感染的总患病率为284(73.96%),阳性病例中,雄性和雌性分别为97(82.91%)和187(70.04%)。研究区绵羊胃肠道线虫主要检出毛线虫111(28.91%)、Oestagia 55(14.32%)、Haemonchus 42(10.94%)、食管口线虫48(12.50%)和鞭虫23(5.99%),寄生虫发生率为85(22.14%)。性别、年龄组、身体状况和季节之间的关系具有统计学意义(分别为P=0.008、P=0.014、P=0.001和P=0.003)。结论:本研究对补充现有的绵羊胃肠道线虫流行病学知识具有重要意义,对该地区应用正确的羊胃肠道线虫防治策略具有重要意义。
