[Chromobacterium violaceum peritonitis: case report and literature review]. / Péritonite à Chromobacterium violaceum: observation et revue de la littérature.

We report a case of Chromobacterium violaceum infection and we review the literature for all published cases. C. violaceum grew from a peritoneal fluid of a 47-year-old woman operated on for peritonitis following perforative gastroduodenal ulcer. She was just coming back from a 1-month-holyday in French Guyana, where she might have been in contact with this micro-organism. The patient fully recovered after surgical management associated with antibiotic therapy consisting of ofloxacin plus piperacillin-tazobactam. Among the more than a hundred of published cases of human infections with C. violaceum that we retrieved, there was not any other case of peritonitis.

Susceptibility of multiresistant serotype 012 Pseudomonas aeruginosa to fosfomycin in combination with other antibiotics.

Serotype 012 represented 15% of 244 isolates of Pseudomonas aeruginosa isolated in the hospital over a 2 year-period and most isolates of this serotype were resistant to multiple antibiotics. Combination experiments showed that fosfomycin and amikacin together were active against 92% of 012 isolates. It is recommended that serotyping be used systematically to identify 012 strains rapidly and fosfomycin/amikacin be considered as a presumptive antipseudomonal therapy in 012 infections.
