Abstract:
Pseudomonas luteola has rarely been reported as a human pathogen. The clinical manifestations of P. luteola bacteremia and its susceptibility to antibiotics have 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 females and 2 males) were diagnosed with P. luteola bacteremia. Six of these patients had hospital-acquired bacteremia, whereas 1 patient had community-acquired P. luteola infection. All patients had monomicrobial bacteremia. Antimicrobial susceptibility testing revealed 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 believe 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.
