Aeromonas aquariorum septicemia and enterocolitis in a cirrhotic patient

Diagn Microbiol Infect Dis. 2012 Dec;74(4):406-8. doi: 10.1016/j.diagmicrobio.2012.08.005. Epub 2012 Sep 17.

Abstract

Aeromonas aquariorum is a recently described Aeromonas species. We present a cirrhotic patient with septicemia and bloody diarrhea in whom A. aquariorum was isolated from the blood and stool. The species identification was based on sequence analysis of the partial rpoB and rpoD genes. The A. aquariorum isolates carried genes encoding hemolysin, aerolysin, and the cytotonic enterotoxin Alt. Significant A. aquariorum-induced cytotoxicity in intestinal epithelial cells was also demonstrated.
