Cyathostomins是最常见的马肠道寄生虫，据报道，这些线虫对所有3种经许可的驱虫类都有耐药性。需要制定较少依赖药物而更多依赖基于管理的控制的战略。为了发展这些，我们需要更好地了解自然传播模式。在这里，我们分析了5个用于保护目的的小马种群的纵向粪卵计数（FEC）数据。我们测试了不同种群和个体的卵子排泄是如何变化的，以及这是如何受到年龄和气候的影响的。有证据表明，随着时间的推移，在个人层面上，FECs具有一致性；这通常是弱的和被解释的
Cyathostomins are the most prevalent equine intestinal parasites and resistance has been reported in these nematodes against all 3 licensed anthelmintic classes. Strategies need to be developed that are less dependent upon drugs and more reliant on management-based control. To develop these we need to understand natural transmission patterns better. Here, we analysed longitudinal fecal egg count (FEC) data from 5 pony populations used for conservation purposes. We tested how egg excretion varied amongst populations and individuals, and how this was affected by age and climate. There was evidence for consistency in FECs over time at the individual level; this was generally weak and accounted for
