Rothia mucilaginosa is found in the oral cavity and pharynx of man where it forms part of the normal
microflora. This organism is also recognized as an opportunistic pathogen causing bacteremia, meningitis
and pneumoniae. We report the first case of bacteremia caused by R. mucilaginosa in Japan. A 68-year-old
male with acute myeloid leukemia received gemtuzumab ozogamicin therapy. The patient had signs of
oral mucositis, and R. mucilaginosa was isolated from blood cultures during prophylactic ciprofloxacin. We
also evaluated the ability of the following kits to identify R. mucilaginosa: PMIC/ID-35, PC.6.1B, GPI card,
API STAPH, API Coryne, rapid ID 32 STREP and N-IDtestSP-18. PMIC/ID-35 and GPI card could identify
this organism, because they had its bacterial code. PC.6.1B could not identify it, and another kit
misidentified it as other gram positive organisms. This study illustrates the possible virulence of R.
mucilaginosa in immunocompromised host with oral mucositis, and indicates that this organism may be
misidentified in the currently used commercial kits.
