Roseomonas spp

• R. cervicalis
• R. fauriae
• R. gilardii
• R. mucosa

• Gram negative coccoid/plump bacilli in pairs/short chains - nonfermenter

Clinical Significance

These organisms are found in a variety of environmental sources. Recent evidence suggests that R. mucosa may be part of normal skin flora. 

Although of low pathogenicity, they have been associated with bacteremia, medical device related infections including CAPD peritonitis, osteomyelitis, wound infections, abscesses or genitourinary infections typically but not exclusively in immunocompromised patients.

Infections associated with medical devices are difficult to treat unless device removed.

Usual Susceptibility Pattern

These organisms are usually susceptible to aminoglycosides, tetracyclines, carbapenems, and quinolones.

They are typically resistant to TMP/SMX, penicillins, and all cephalosporins.
