Colitis ulcerativa histiocítica por Escherichia coli enteropatogénica en bulldog francés de 8 meses.

Abstract

A male canine, French bulldog breed, 8 months old, was admitted to the Perros y Gatos Veterinary Clinic, with vaccination and deworming plan in force, reporting intestinal problems with hematochezia, tenesmus and coprophagia. They also referred that the patient had multiple examinations and was treated in another clinic, which did not present favorable evolution. In the clinical and semiological evaluation, normal parameters were found. Diagnostic plans such as: hemoleukogram, blood chemistries, coprological and coproscopic (increased intestinal microbiota and Giardia spp were observed), colonoscopy and biopsy, histopathology, stool culture (positive for the presence of enteropathogenic E. coli) and antibiogram were used. Taking into account the report of the aforementioned tests, histiocytic or granulomatous ulcerative colitis was diagnosed, being considered an idiopathic immune-mediated disease, with persistent or recurrent nonspecific symptomatology. To eliminate the bacteria and control the chronic symptomatology, home treatment was established: ciprofloxacin, prednisolone and a rigorous diet of hydrolyzed proteins; in conclusion, the patient presented a favorable evolution since the hematochezia decreased almost completely and a control stool culture was performed to determine if he was still positive for enteropathogenic E. coli.
