Background:

Raoultella ornithinolytica is a rare encapsulated gram-negative facultative anaerobe bacterium belonging to Enterobacteriaceae family. Raoultella orthinolytica is a rare cause of infections in humans. It is an under-reported, virulent pathogen found in community and hospital acquired infections following invasive procedures. Infections attributable to Raoultella ornithinolytica are relatively serious presenting as bacteraemia, sepsis, pneumonia, joint infections, biliary infections and peritonitis. However, it has not been identified as the sole pathogen in infected wounds following clean procedures like breast reduction surgery. A case of polymicrobial involvement with Raoultella ornithinolytica after breast reduction has been reported in one study (1).

We report a case of wound infection after breast reduction surgery  solely caused by Raoultella ornithinolytica. The aim of the study is to make surgeons cautious of virulent wound infections with otherwise uncommon micro-organisms in patients who have had surgeries abroad.
