Shewanella putrefaciens: a rare cause of purulent otorrhoea.

Shewanella putrefaciens is a Gram-negative, non-fermenting, motile and oxidase-positive bacillus. Its incrimination in human pathology is very rare, although there has been a resurgence in Shewanella infections in recent years. We report the first case in Morocco of a purulent otorrhoea caused by S. putrefaciens , resistant to conventional treatment, occurring in a 25-year-old female, afebrile, without deterioration of the general state and possibly acquired during sea bathing. We also describe the bacteriological characteristics of and antibiotic susceptibility results for the isolate.
