The study was carried out on an organic farm. The flock of the sheep (27 individuals) was naturally infected by parasites. The aim of the study was to estimate the prevalence of infection with gastrointestinal nematodes. There were found species of 3 nematode families: Trichostrongylidae (Trichostrongylus spp., Ostertagia sp., Nematodirus spp., Cooperia spp., Haemonchus contortus); Strongylidae (Oesophagostomum spp., Strongyloides papillosus, Chabertia ovina) and Ancylostomatidae (Bunostomum sp.). Three nematode genera were dominant in parasite infection: Trichostrongylus, Ostertagia and Nematodirus. The prevalence of sheep infection with gastrointestinal nematodes were nearly 100%. The main species were Trichostrongylus spp. (59.2%) and Ostertagia sp. (46%).
该研究在一个有机农场进行。这群羊（27只个体）自然感染了寄生虫。该研究的目的是估计胃肠道线虫的感染率。发现了3个线虫科的种类：毛圆科（毛圆线虫属、奥斯特他线虫属、细颈线虫属、古柏线虫属、捻转血矛线虫）；圆线科（食道口线虫属、乳头类圆线虫、夏伯特线虫）和钩口科（仰口线虫属）。在寄生虫感染中，三个线虫属占主导地位：毛圆线虫属、奥斯特他线虫属和细颈线虫属。绵羊胃肠道线虫感染率接近100%。主要种类是毛圆线虫属（59.2%）和奥斯特他线虫属（46%）。
