A total of 278 Thoroughbreds (less than 1 to 31 years old) were examined at necropsy (July 9, 1985, to Feb 2, 1986) in Kentucky for various internal parasites. Examination was not made of all the horses for each of the parasites. Specific parasites recovered from the stomach of foals (n = 30) and yearlings and older horses (n = 96) and percentage (in parentheses) of each age category infected, respectively, were as follows: Gasterophilus intestinalis 2nd instar (53% and 32%) and 3rd instar (37% and 24%); G nasalis 2nd instar (7% and 8%) and 3rd instar (7% and 10%); Habronema spp immature (7% and 13%); H muscae (3% and 8%); Draschia megastoma (3% and 5%) and lesions (0% and 2%); and Trichostrongylus axei (0% and 3%). Parasites in the large intestine included Anoplocephala perfoliata, which was found in the cecum of 30% of the foals (n = 87) and in 60% of the yearlings and older horses (n = 186). Probstmayria vivipara and immature Oxyuris equi were not found in the colon and rectum of any of the horses (n = 53 foals and n = 101 yearlings and older); mature O equi were not sought. Examination of the cranial mesenteric artery for Strongylus vulgaris revealed immature and/or mature specimens in 9% of foals (n = 87) and 14% of yearlings (n = 44); lesions of S vulgaris were present in 25% of foals (n = 87) and 34% of yearlings (n = 44).
1985年7月9日至1986年2月2日期间，在肯塔基州对278匹纯种马（年龄不到1岁至31岁）进行了尸检，以检查各种体内寄生虫。并非对每匹马都检查所有寄生虫。从驹（n = 30）、一岁马及成年马（n = 96）胃中检出的特定寄生虫及各年龄组的感染率（括号内）分别如下：肠胃蝇第二龄幼虫（53%和32%）和第三龄幼虫（37%和24%）；鼻胃蝇第二龄幼虫（7%和8%）和第三龄幼虫（7%和10%）；柔线虫属未成熟虫体（7%和13%）；蝇柔线虫（3%和8%）；大口德拉什线虫（3%和5%）及病变（0%和2%）；以及马圆形线虫（0%和3%）。大肠中的寄生虫包括叶状裸头绦虫，在30%的驹（n = 87）盲肠中以及60%的一岁马及成年马（n = 186）中发现。在任何一匹马（n = 53匹驹和n = 101匹一岁马及成年马）的结肠和直肠中均未发现胎生普氏线虫和未成熟的马尖尾线虫；未查找成熟的马尖尾线虫。对肠系膜前动脉检查普通圆线虫，在9%的驹（n = 87）和14%的一岁马（n = 44）中发现未成熟和/或成熟虫体；25%的驹（n = 87）和34%的一岁马（n = 44）有普通圆线虫病变。
