The objective of the present study was to determine the prevalence and associated determinants (e.g., sex, age, on-farm management and husbandry) of gastrointestinal (GI) helminths in the domestic animals of district Toba Tek Singh, Punjab, Pakistan. For this purpose, 1,140 cattle, 1,140 buffaloes, 660 goats, 840 sheep, and 156 camels were randomly selected and their fecal samples were screened every other week for a year using a modified floatation technique. The samples positive for strongyle-type eggs had the parasite species identified using coproculture. It was found that the prevalence of GI helminths was significantly higher (P < 0.05) in sheep (44.17%; 371/840) than in other livestock. Sheep were followed in order by goats (40.15%; 265/660), buffaloes (39.82%; 454/1,140), and cattle (33.68%; 384/1,140). The important helminth species identified were Fasciola (F.) gigantica, Fasciola hepatica, Haemonchus contortus, Toxocara vitulorum, Trichostrongylus spp., Oesophagostomum spp., Ostertagia spp., Cooperia spp., Strongyloides spp., Moniezia spp., and Trichuris spp. The prevalence of GI helminths except F. hepatica and F. gigantica was significantly higher in grazing animals, females (P < 0.05) and young (P < 0.05) of all the host species when compared with stall-fed animals, males and adults, respectively. Using ponds and rivers/canals as drinking water were found to have significant influence (P < 0.05) on the prevalence of GI helminths. The results provide a baseline data for planning future research and control strategies against GI helminthes.
本研究旨在确定巴基斯坦旁遮普省多巴塔克辛格地区家畜胃肠道（GI）蠕虫的流行情况及其相关决定因素（如性别、年龄、农场管理和畜牧业）。为此，随机选择了 1140 头牛、1140 头水牛、660 只山羊、840 只绵羊和 156 只骆驼，每两周用改良漂浮技术对其粪便样本进行一次筛查，持续一年。对强旋毛虫卵呈阳性的样本用粪培养法鉴定寄生虫种类。结果发现，绵羊（44.17%；371/840）的 GI 蠕虫感染率明显高于其他家畜（P<0.05）。其次是山羊（40.15%；265/660）、水牛（39.82%；454/1140）和牛（33.68%；384/1140）。鉴定出的重要蠕虫种类有肝片吸虫（Fasciola）、双腔吸虫（Fasciola）、捻转血矛线虫（Haemonchus contortus）、细颈囊尾蚴（Toxocara vitulorum）、毛圆科线虫（Trichostrongylus spp.）、奥斯特线虫（Oesophagostomum spp.）、网尾线虫（Ostertagia spp.）、结肠小袋纤毛虫（Cooperia spp.）、类圆线虫（Strongyloides spp.）、孟氏旋毛线虫（Moniezia spp.）和毛首线虫（Trichuris spp.）。与舍饲动物相比，放牧动物、所有宿主物种的雌性（P<0.05）和幼畜（P<0.05）的 GI 蠕虫感染率除肝片吸虫和双腔吸虫外均明显更高。使用池塘和河流/运河作为饮用水对 GI 蠕虫的流行有显著影响（P<0.05）。研究结果为今后针对 GI 蠕虫的研究和控制策略提供了基线数据。
