A fatal case of iliopsoas abscess caused by Salmonella enterica serovar Choleraesuis that heterogeneously formed mucoid colonies.
Salmonella enterica subsp. enterica serovar Choleraesuis, an organism highly adapted to swine, rarely causes invasive human infection. We describe a fatal case of Salmonella ser. Choleraesuis infection developing iliopsoas abscess. A part of organisms recovered from the blood formed mucoid colonies, which became reactive to anti-O antigen antisera after either heat treatment or subculture through semisolid agar.
