A gram-negative facultative anaerobic bacterium primarily isolated from sea water, which reduces iron and manganese and produces trimethylene–the chemical responsible for the odour of rotting fish. It is not part of normal human flora.
Clinical findings It is a rare human pathogen and may be found in mixed cultures from the respiratory tract, urine, faeces, and pleural fluid. It has been implicated in cellulitis, otitis media, septicaemia and here infects a koi.
Synonyms Achromobacter putrefaciens, Alteromonas putrefaciens, Pseudomonas putrefaciens
