摘要: A quantitative post mortem study of 150 horses from Victoria was conducted to determine the prevalence and epidemiology gastrointestinal parasites. total 42 species metazoan parasite found. The following non-cyathostome were found (% prevalence): Trichostrongylus axei (51%); Habronema muscae (13%); H. majus (2%); Draschia megastoma (5%); Gastreophilus intestinalis (81%); G. nasalis (29%); Parascaris equorum Anoplocephala perfoliata Fasciola hepatica (0.7%); Oxyuris equi (7%); Strongylu vulgaris (23%); S. edentatus equinus (3%); Craterostomum acuticaudatum Triodontophorus serratus (8%); T. tenuicollis brevicauda (3%). Ninety-five per cent infected with gut-wall encysted stages cythostomes a mean intensity 113,000 larvae horse. Ninety-three all harboured adult cyathosome worms; 24 representing 6 genera 3 most prevalent Cylicostephanus longiburstatus (76%); Cyathostomum catinatum (68%) Cylicocyclus nassatus (54%). Seventeen strongyle present in high abundance, which allowed their site distribution large intestine be determined. Twelve preferred colon small caecum, remaining 5 caecum. Statistical analysis parasitological data set effects sex, age, type, physical condition horse as well season environment on infection
