Abstract：
The aims of the present study were: (a) to describe the prevalence of helminth infections from pooled faecal samples from sheep flocks across Greece and (b) to evaluate flock-related factors potentially associated with the presence of these infections in the flocks. An extensive countrywide study was performed on 325 sheep farms throughout Greece; faecal samples were collected from ewes and processed for the identification of helminth parasites. Helminths were detected in samples from 92.9% of flocks; these included Dicrocoelium dendriticum (16.7% of flocks), Fasciola hepatica (0.6%), Paramphistomum cervi (2.2%), Moniezia spp. (18.8%), Trichostrongylidae (85.5%), Nematodirus spp. (18.8%), Strongyloides papillosus (7.1%), Trichuris spp. (20.0%) and lungworms (17.8%). Mean Trichostrongylidae counts across all flocks in the study were 215 epg. Specifically, for Trichostrongylidae, there were differences between flocks that had or had not received anthelmintics during the two months prior to sampling, as well as between flocks located in various areas of the country. In multivariable analyses, for the outcome \'high (>300) epg counts in faecal samples\', the month into the lactation period at sampling and the application of reproductive control practices on the farm emerged as significant factors; for the outcome \'high proportion (>63%) of Teladorsagia spp. in faecal samples\', the availability of straw bedding emerged as a significant factor; and for the outcome \'high proportion (>63%) of Haemonchus contortus in faecal samples\', the age of the farmer emerged as a significant factor. For the outcome \'presence of Trichuris spp. in faecal samples\', the provision of finished feed (concentrate) to animals emerged as a significant factor, whilst, finally, for the outcomes \'presence of D. dendriticum in faecal samples\' and \'presence of lungworms in faecal samples,\' no significant factors emerged.
摘要：
本研究的目的是：（a）描述希腊各地羊群的粪便样本中蠕虫感染的患病率，以及（b）评估与羊群中这些感染的潜在相关因素。在整个希腊的325个绵羊养殖场进行了广泛的全国研究；从母羊中收集粪便样本，并对其进行处理以鉴定蠕虫寄生虫。在92.9％的羊群的样品中检测到蠕虫；这些包括树枝状二球菌（占羊群的16.7％），肝片吸虫（0.6%），两栖动物宫颈(2.2%),Monieziaspp.（18.8%），毛线菌(85.5%),线虫属。（18.8%），乳头类圆线虫（7.1%），毛虫属。(20.0%)和肺虫(17.8%)。研究中所有羊群的平均毛线菌计数为215epg。具体来说,对于Trichostrongylyalae，在采样前两个月接受或未接受驱虫药的羊群之间存在差异，以及位于全国各地的羊群之间。在多变量分析中，对于“粪便样本中的高(>300)epg计数”的结果，取样时进入哺乳期的月份和在农场应用生殖控制措施是重要因素；对于结果，Teladorsagiaspp的比例很高（>63％）。在粪便样本中，秸秆垫层的可用性成为一个重要因素；对于结果“粪便样本中的高比例（>63％）的扭动血杆菌”，农民的年龄成为一个重要因素。对于毛虫属的结果。在粪便样本中，向动物提供成品饲料(浓缩物)是一个重要因素，while,最后,对于结果\“粪便样本中存在树状芽孢杆菌”和粪便样本中存在肺虫，\'没有出现重要因素。
