Case report: isolation of from septic blood culture following near-death drowning in lakewater.

A patient suffered a non-fatal wet drowning in a freshwater lake and developed bacteraemia several days later. Blood culture grew a Gram-negative rod that could not be identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). 16S ribosomal RNA sequencing of the isolate identified the microbe as - an environmental microbe commonly found in freshwater. The recovery of multiple pathogenic micro-organisms (although not ) from culture of respiratory specimens prompted the initiation of antibiotic therapy with cefepime and, later, vancomycin. The patient's clinical course gradually improved over the course of 2 weeks and she was ultimately discharged home with minimal sequelae. To our knowledge, this is the first evidence of human infection with bacteria in the genus . may be considered in cases of freshwater near-drowning, and MALDI-TOF MS databases should be updated to include .
