“…Chryseomonas luteola is an aerobic, oxidase-negative, Gram-negative rod that produces a yellow pigmented colony (Anon (Pure Air Controls) 2004a). It is widely distributed in both nature and in hospital environments and is associated with nosocomial infections in humans (Anon (Pure Air Controls) 2004a; Chihab et al 2004).…”

Enterobacter sakazakii has recently been identified as an opportunistic pathogen. The current culture-dependent detection methods for these bacteria are time-consuming and in this study a PCR method for the detection of E. sakazakii in South African food products, including an internal amplification control (IAC) was developed. DNA was isolated and amplified from the products and they were plated on selective growth media after pre-enrichment and enrichment in Enterobacteriaceae enrichment broth. Four of the 22 products tested positive for the presence of E. sakazakii, confirmed by PCR detection and growth on selective media. The PCR method proved effective in detecting E. sakazakii in South African products after three days and could serve as an alternative for traditional microbiological techniques.

“…It is a rare cause of pathogenic human infection and has been reported to cause septicemia, endocarditis, and peritonitis among immunocompromised individuals or individuals with indwelling devices. 3,4 While P. aeruginosa causes a devastating form of endophthalmitis, P. luteola is associated with a more indolent course. P. luteola endophthalmitis was characterized by gradually worsening hypopyon, vitritis, IOP elevation, and light-colored deposits capsular deposits similar to Pseudomonas oryzihabitans infection.…”

An interventional case report is described of a patient with chronic postoperative endophthalmitis caused by the gram-negative aerobic rod Pseudomonas luteola. A 61-year-old developed slowly progressive blurring of vision, hypopyon, and vitritis following cataract surgery. Diagnostic vitrectomy and intraocular lens explantation were performed. The undiluted vitreous samples and explanted lens were analyzed. Aerobic cultures revealed moderate growth of P. luteola. The patient responded to intravitreal injections of piperacillin/tazobactam and oral trimethoprim/sulfamethoxasole. Best-corrected visual acuity improved from hand motions to 20/40. A repeat anterior chamber tap was negative. P. luteola may be a relatively nonvirulent cause of chronic endophthalmitis. Good visual outcomes may be obtained with appropriate therapy.

“…In the present study, P. luteola isolates were highly resistant to colistin in vitro, and empirical colistin treatment failed in 1 patient. It was reported that monotherapy was sufficient in most cases (5,9,17,20). We believe that carbapenems might be suitable for hospital-acquired P. luteola infections, as all of the isolates studied were susceptible to imipenem.…”

“…In a study from Tanzania that investigated extended spectrum beta-lactamases among gram-negative bacteria of nosocomial origin, P. luteola was reported as a nosocomial pathogen in 1 patient in an intensive care unit of a tertiary hospital (4). In this study, we reviewed all cases of infection related to P. luteola from 1988 to date (Table 4) (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24). Of the reported cases of P. luteola, bacteremia was the most common infection.…”

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.
