A survey was conducted on the prevalence of the major gastrointestinal parasites in 140 horses necropsied in Perth, Western Australia, during 1979 to 1982. Adult Strongylus vulgaris were found in 22.5 per cent of horses and verminous arteritis in 62.9 per cent. The peak worm prevalence was in November to January (summer). S edentatus had a similar prevalence and seasonality but S equinus was not found in this survey. Draschia megastoma and Habronema muscae were found in 66.2 per cent and 35.3 per cent of horses respectively. Infection is probably acquired in summer when 8 per cent of the Musca domestica in the vicinity of the stables carried third stage spiruroid larvae. Gasterophilus intestinalis and G nasalis occurred in 36.4 per cent and 22.1 per cent of the horses respectively and 52.1 per cent of horses were infected with one or both species. The peak prevalence of G intestinalis larvae occurred in December with a trough in February-April; the peak prevalence of G nasalis was in May with a trough in November-December. Parascaris equorum was found in 9.9 per cent of the horses and in 21.3 per cent of those less than three years old. Anoplocephala perfoliata was found in 4.9 per cent of the horses and most of these were in older horses.
1979年至1982年期间，对西澳大利亚珀斯地区剖检的140匹马的主要胃肠道寄生虫感染率进行了调查。22.5%的马体内发现了普通圆线虫成虫，62.9%的马患有蠕虫性动脉炎。蠕虫感染率高峰出现在11月至1月（夏季）。定居圆线虫的感染率和季节性与之相似，但本次调查未发现马圆线虫。大口德拉吸虫和蝇柔线虫分别在66.2%和35.3%的马体内被发现。感染可能发生在夏季，此时马厩附近8%的家蝇携带第三期旋尾类幼虫。肠胃蝇和鼻胃蝇分别在36.4%和22.1%的马体内出现，52.1%的马感染了其中一种或两种。肠胃蝇幼虫感染率高峰出现在12月，2月至4月为低谷；鼻胃蝇感染率高峰出现在5月，11月至12月为低谷。9.9%的马体内发现了马副蛔虫，在3岁以下的马中，这一比例为21.3%。4.9%的马体内发现了叶状裸头绦虫，其中大多数为老龄马。
