An Uncommon Encounter of Roseomonas gilardii Bacteremia: A Case Report.

ABSTRACT

Roseomonas genus was initially described in 1993 as a "pink coccoid." It is a non-fermentative, aerobic, and gram-negative bacteria. This genus has been uncovered in diverse environmental niches, ranging from water and soil to air and plants. Despite its prevalence in the natural world, human infections stemming from Roseomonas species remain a rare occurrence. This organism is also known to be resistant to standard antibiotics. We present a case of an 85-year-old woman with Roseomonas gilardii (RG) bacteremia who is a resident at an assisted living facility. Healthcare providers should consider this bacterium in slow-developing gram-negative infections, potentially opting for broad-spectrum antibiotics as an initial treatment.
