Bacteremia Caused by Pseudomonas luteola in Pediatric Patients

Abstract

SUMMARY: 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.

Novel Approach to Microbiological Study of Chronic Inflammations at Upper Respiratory Tract: Research of Blood L-Form Microbiota

“…Similar combination of Pseudomonas luteola and Escherichia vulneris has been reported to cause "round pneumonia", in which the lesion has been detected on the chest radiographs as solitary lung nodule, which are first suspected to be a lung cancer [23]. Infections with Pseudomonas luteola are less common, but cases of bacteremia, empyema, endocarditis, post-surgical infections and peritonitis have been reported [24]. Enterobacter cloacae is involved in the normal intestinal microbiota in many people.…”

Post-surgical Gangrene with Pseudomonas luteola Resulting in Limb Amputation: A Case Review

“…As was seen in this instance, P. luteola can be involved in infections that lead to severe morbidity, and may even result in mortality. In their retrospective study, Bayhan et al assessed the number of cases of P. luteola at a pediatric hospital [ 16 ]. They found that the majority of cases of P. luteola (85.7%, 6/7 patients) were hospital acquired and that nosocomial infection by the pathogen tended to present as bacteremia.…”

Round pneumonia with Pseudomonas luteola and Escherichia vulneris bacteremia

“…Pseudomonas luteola (formerly Chryseomonas luteola) is a catalase positive, oxidase negative, motile Gram negative bacillus of the family Pseudomonaceae. 2 While P. luteola infections are less common than those of P. aeruginosa, there have been case reports of the bacterium causing bacteremia, empyema, prosthetic valve endocarditis, post-surgical infections, and peritonitis. [3][4][5][6] Although most often found in the soil and water sources, P. luteola has been isolated in animals, including turtles, tortoises and fish.…”
