Ulcerative typhlocolitis and peritonitis in cattle due to Salmonella spp.

The objective of this study was to report clinical, epidemiological, and anatomopathological data in cattle affected by colitis and perforating ulcerative typhlitis with peritonitis; three (n=3) bovines affected by colitis and two (n=2) with ulcerative typhlocolitis. Clinically, apathy stood out, accompanied by difficulty in exploring the abdominal organs through rectal palpation because of low mobility of the organs due to adhesions. The animals died, and, on necroscopic examination, diffuse, fibrinous purulent peritonitis was recorded due to perforating, multifocal ulcerated areas in the colon and cecum wall. Histopathological examination recorded data compatible with acute, necrotizing, and perforating ulcerative enteritis, with thrombus in the blood vessels associated with fibrinoid necrotizing vasculitis. The immunohistochemistry test for Salmonella spp. was positive in four of the five samples analyzed. The etiopathogenesis of perforating ulcerative typhlocolitis in cattle is associated with infection by Salmonella spp., while not ruling out the possibility of participation of other etiologic agents in the occurrence of this disease, due to the complexity of the disease and the scarcity of reports in the literature, further investigations are necessary to provide a better understanding of this disease in cattle.
