Abstract

Roseomonas is a genus of pink-pigmented, oxidative, gram-negative coccobacilli and rarely causes opportunistic infection. We report a case of wound infection by Roseomonas species in a 53-yr-old man with alcoholic liver cirrhosis. 16S ribosomal RNA (rRNA) gene sequencing was performed to confirm the infectious agent. The patient recovered without complication after ciprofloxacin treatment. To the best of our knowledge, this is the first case of Roseomonas infection reported in Korea.
