title: Prevalence of Anoplocephala perfoliata and lesions of Draschia megastoma in Thoroughbreds in Kentucky at necropsy.
abstract: A total of 396 Thoroughbreds (86 males, 293 females, and 17 geldings) in Kentucky, 1 to 30 years of age, were examined at necropsy for presence of Anoplocephala perfoliata (2 female horses were not examined) in the cecum for lesions of Draschia megastoma in the stomach, during the 1-year period of Mar 1, 1982 through Feb 28, 1983. Prevalence of A perfoliata was 53% and of lesions of D megastoma was 63%. All lesions of D megastoma were partially or entirely in the glandular region of the stomach. Distances of the midpoint of these lesions from the margo plicatus varied from 0 to 290 mm. The center of about 88% of the lesions was within 50 mm of the margo plicatus . Measurements of the size of the lesions, exclusive of masses, indicated that about 95% were less than or equal to 50 mm in diameter. There appeared to be a higher infection rate of lesions of D megastoma in younger horses (81% in 1 to 7 year olds) than in older horses (41% in 8 to 30 year olds) with a few exceptions.
