title: The pathogenesis of porcine rectal stricture. I. The naturally occurring disease and its association with salmonellosis.
abstract: Rectal stricture occurred in each of 23 pigs submitted for necropsy from eight Indiana farms. Each stricture was an annular cicatrization of the rectal wall, 2.0-5.0 cm anterior to the anorectal junction. Emaciation, colonic dilatation and compression atrophy of abdominal and thoracic viscera were a result of chronic obstipation and inanition. Most pigs with strictures had severe enteric disease 4-8 weeks before the strictures occurred. Salmonella typhimurium was isolated from seven of the eight groups of pigs examined. Ulcerative proctitis, a possible precursor of rectal stricture, was frequently in pigs with enterocolitis caused by S. typhimurium.
