Fifty-five adult horses were necropsied over a 15-month period, and their worm burdens counted and speciated. Twenty-one species of Cyathostominae were recovered. Ten species: Cyathostomum catinatum, Cylicocyclus nassatus, Cylicostephanus longibursatus, Cyathostomum coronatum, Cylicostephanus goldi, C. calicatus, C. minutus, Cylicocyclus leptostomus, C. insigne and Cyathostomum pateratum, comprised 98.9% of the total cyathostome burdens. These same 10 species also demonstrated high prevalences in 4 previous surveys. Eight of these 10 species have been shown to be resistant to benzimidazole anthelmintics. Anthelmintic resistance apparently had little effect on the prevalence of a species, but appeared to increase its relative abundance within a mixed population. The prevalence of other internal parasites was similar to previous reports, but Strongylus vulgaris adults and arterial lesions were less common.
在15个月的时间里，对55匹成年马进行了尸检，统计并鉴定了它们体内的蠕虫负荷。共发现了21种圆线虫亚科线虫。其中10种：卡氏圆线虫、鼻状环行线虫、长囊环冠线虫、冠状圆线虫、戈氏环冠线虫、杯状环冠线虫、微小环冠线虫、细口环行线虫、显著环行线虫和父性圆线虫，占圆线虫总负荷的98.9%。在之前的4次调查中，这10种线虫的感染率也很高。这10种线虫中有8种已被证明对苯并咪唑驱虫药具有抗性。驱虫药抗性显然对一个物种的感染率影响不大，但似乎会增加其在混合种群中的相对丰度。其他体内寄生虫的感染率与之前的报告相似，但普通圆线虫成虫和动脉病变较少见。
