A variety of enteric deseases may result in the manifestation of abdominal pain in horse. 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. equrum) infection in cmall intestine. In addition, it is also noted the presence of P. equorum in the stomach. Infection due to P. equorummanifests itself in foals between 6-8weeks 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.
