“…6,7 In children, only few sporadic cases of Roseomonas isolation have been reported, some being incompletely documented or corresponding to transient colonization. [12][13][14] In 2006, McLean et al 14 reviewed 7 pediatric cases of catheter-related bacteremia involving Roseomonas gilardii (n = 3), Roseomonas sp. (n = 3), and Roseomonas fauriae (n = 1) identified by phenotypic methods.…”

“…Outcome was favorable in all cases reviewed here (Table 1) In children with ALL, 3 cases of Roseomonas bacteremia have been previously reported and attributed to an unidentified species (n = 1) 12 and to R. gilardii (n = 2). 12,13 However, identification should be considered with caution because the isolates have been identified by phenotypic means only and cases have been reported before the R. mucosa characterization in 2003. 7 Common features were the fever upon Roseomonas isolation and the favorable outcome under treatment including an association of ceftazidime and gentamicin or amikacin.…”

Roseomonas are described as opportunistic pathogens rarely involved in human infections. Their identification requires molecular methods and their antimicrobial susceptibility pattern varies according to the species. We report the first case of bacteremia due to Roseomonas mucosa in a child with leukemia and reviewed pediatric cases of Roseomonas infection, for which undoubted strain identification was available. Favorable outcome was observed despite resistance to numerous β-lactams that may account for delayed effective treatment, suggesting the low virulence of Roseomonas in children. Here, the strain also displayed unusual resistance to imipenem, highlighting the possible acquisition of additional resistance by this pathogen.

“…On the other hand, infections due to Roseomonas spp. are distinctly rare in the pediatric population, with a total of seven cases reported to date; R. gilardii was identified in three, R. fauriae was identified in one, and three were reported as species unknown (6,7,13). To our knowledge, R. mucosa has not been identified in any pediatric patients.…”

Roseomonas mucosa Isolated from Bloodstream of Pediatric Patient

We report a case of catheter-related bacteremia associated with Roseomonas mucosa isolated from an immunocompromised pediatric patient with a history of multiple episodes of urinary tract infection and bacteremia. CASE REPORTAn 18-year-old male presented to the UCLA Emergency Department with a 2-day history of fever, malaise, and decreased activity level and was admitted to the UCLA Medical Center for suspected catheter-related sepsis. The patient had a past medical history that included pseudoobstruction, status postcolectomy, chronic total parenteral nutrition dependence, and G-tube placement. In addition to having multiple incidences of urinary tract infections with Morganella species and Enterococcus species, the patient has also had multiple episodes of bacteremia in the past 2 years with Methylobacterium mesophilicum, Acinetobacter lwoffii, Delftia acidovorans, and another unidentified Gram-negative bacillus. The patient's last admission to the UCLA Medical Center was 9 months ago for Broviac catheter-related bacteremia with Delftia acidovorans and the unidentified Gram-negative bacillus. For these past infections, the patient was treated with extended-spectrum cephalosporins, gentamicin, and ciprofloxacin. Blood samples were collected for culture, and the patient was empirically treated with vancomycin and ceftriaxone.Two sets of BactT/Alert aerobic and anaerobic blood culture bottles were drawn from the Broviac catheter line within a 24-hour period. Bacterial growth was detected in one aerobic bottle on day 4 of incubation, using the BacT/Alert (bioMérieux, Marcy l'Etoile, France). Gram-negative coccobacilli were detected on Gram stains, and the organism was subcultured to MacConkey agar, blood agar, and chocolate agar and incubated at 35°C in 5% CO 2 . Growth on blood agar and chocolate agar revealed slightly pink, mucoid colonies; no growth was observed on MacConkey agar. The organism was further subcultured to Sabouraud dextrose (SAB) agar, which grew prominent pink mucoid colonies after 24 h incubation (Fig.

“…7 The agar gradient diffusion (Etest) method has also been employed for determining in vitro susceptibilities. 8,14,16 Since there are no published methodological guidelines or interpretive breakpoints for minimal inhibitory concentrations (MICs) specific for Roseomonas spp., there are no recommendations for clinical laboratories to perform in vitro susceptibilities for individual patient management. If susceptibility testing is performed, it is best to limit reports to the MIC value and not provide an interpretation.…”
