An acute colic in a 5-month-old Thoroughbred filly is described. The filly was presented with acute colic characterized by rolling and pawing. Next day she suffered from severe abdominal pain and subsequently died. Post mortem examination revealed very heavy ascarid, Parascaris equorum (P. equorum) infection in small intestine. In addition, it is also noted the presence of P. equorum in the stomach. Infection due to P. equorum manifests itself in foals between 6-8 weeks and one year of age. P. equorum is a common and ubiquitous parasite that persists for many years in stables and on pasture in spite of good hygiene and anthelmintic control programs. Key words : Thoroughbred filly, colic, ascarid impaction, Parascaris equorum. * V. f B÷V* Ç" ÿö ~«' î~ b Ò' _f VË' öê(obstruction)f ? · ö b B . ¾ rJê /W ;î~~ öf Strongylus vulgaris 5 ascaridsf ?f VÏ, ", Ò ò~ /·Ê æã, Î¾ S, Ë" 5 Salmonella sp. f ?f 6"W ÷öÚ ® .
