Unusual clinical presentation of infection due to Flavimonas oryzihabitans

Abstract

Six cases of Flavimonas oryzihabitans infection are presented, four of which were community-acquired pneumonia and two of which were nosocomially acquired bacteremia. All four cases of pneumonia occurred in immunosuppressed hosts, three of whom were HIV-positive individuals and one of whom was a young man affected by chronic myeloid leukemia. Flavimonas oryzihabitans is recognized with increasing frequency as a cause of opportunistic infection, but the present cases of community-acquired pneumonia due to this organism are believed to be the first four reported in the English literature. The findings emphasize that Flavimonas oryzihabitans should be included in the list of pathogens that cause community-acquired infections in the immunocompromised host.
