很少有研究描述了年龄，性别，管理和控制方案的蠕虫流行和鸡蛋脱落放牧马的综合影响。在这里，粪便样本收集1221纯种马，居住在22个螺柱在英国，进行了分析。调查了圆线虫卵在个体中的分布与年龄、性别和管理措施的关系。粪虫卵计数（FWEC），描述为每克粪便（epg）的虫卵数，采用改良的盐浮选法测定。圆线虫、马副蛔虫、绦虫的FWEC患病率（平均%）。魏氏圆线虫为56、9、4和8%。圆线虫、马疫霉、绦虫属。和S.分别在22只（100%）、11只（50%）、9只（41%）和8只（36%）螺柱中检测到了韦斯特氏菌感染。在所有年龄和性别类别中，圆线虫FWEC在马中高度过度分散（算术平均值= 95 epg，聚集参数k=0.111）。动物年龄、最后使用的驱虫剂类型和管理措施（例如，放牧时的分组轮换）对强线虫的流行和产卵水平影响最大（P
Few studies have described the combined effect of age, gender, management and control programmes on helminth prevalence and egg shedding in grazing equines. Here, fecal samples collected from 1221 Thoroughbred horses, residing at 22 studs in the UK, were analysed. The distribution of strongyle eggs amongst individuals in relation to age, gender and management practices was investigated. Fecal worm egg counts (FWECs), described as the number of eggs per gramme (epg) of feces, were determined using a modification of the salt flotation method. The FWEC prevalence (mean%) of strongyles, Parascaris equorum, tapeworm spp. and Strongyloides westeri was 56, 9, 4 and 8%, respectively. Strongyle, P. equorum, tapeworm spp. and S. westeri infections were detected on 22 (100%), 11 (50%), 9 (41%) and 8 (36%) of studs, respectively. Within all age and gender categories, strongyle FWECs were highly over- dispersed (arithmetic mean = 95 epg, aggregation parameter k=0.111) amongst horses. Animal age, last anthelmintic type administered and management practices (for example, group rotation on grazing) most strongly influenced strongyle prevalence and level of egg shedding (P
