Bacteremia caused by Pseudomonas luteola in pediatric patients

Abstract

Pseudomonas luteola has rarely been reported as a human pathogen. The clinical manifestations of P.luteola bacteremia and its susceptibility to antibiotics has not been characterized. This retrospective study was conducted at a 382-bed tertiary care center in Turkey. During the 9-year study period 7 patients (5 female and 2 male) were diagnosed with P.luteola bacteremia. 6 of the 7 patients had hospital-acquired bacteremia, whereas 1 patient had community-acquired P.luteola infection. All patients had monomicrobial bacteremia. Antimicrobial susceptibility testing showed that all strains of P.luteola were sensitive to amikacin, gentamicin, trimethoprim/sulfamethoxazole, and meropenem, and that all strains were resistant to piperacillin/tazobactam, aztreonam, and colistin. In conclusion, we think that P.luteola can cause both community- and hospital-acquired bacteremia. Amikacin, gentamicin, trimethoprim/sulfamethoxazole, and meropenem were effective against P.luteola in the present study.
