An infant with a large-bowel obstruction due to Salmonella B enterocolitis
is presented. The clinical and radiologic findings were suggestive of Hirsc
hsprung's disease with total colonic aganglionosis. Due to further deterior
ation, an ileostomy was performed. Pathologic examination disclosed ganglia
in the colon. At laparatomy, 1 month later the colon, which was almost com
pletely obliterated, was resected and an ileorectal anastomosis carried out
. The patient remained a carrier of a multiple antibiotic-resistant group B
Salmonella strain, and 2 months later died as a result of severe gastroent
eritis.
