Meningitis due to a Combination of < b > < i > Streptococcus mitis < /i > < /b > and < b > < i > Neisseria subflava < /i > < /b > : A Case Report

We report a rare case of meningitis due to a combination ofStreptococcus mitis andNeisseria subflava. An 80-year-old female had a 4-year history of type II diabetes mellitus (DM) and an 11-year history of rheumatoid arthritis, which was treated with prednisolone, tacrolimus, and methotrexate. One month after the removal of a dental implant, she complained of a disturbance of consciousness and suffered a convulsion. A cerebrospinal fluid culture was found to be positive for bothS. mitis andN. subflava. After 14 days of antibiotic treatment with 4 g/day ceftriaxone, her stiff neck, somnolence, and laboratory data greatly improved, and she was successfully discharged at 27 days after admission. Although bothS. mitis andN. subflava are generally considered to be benign bacteria, they can cause meningitis in patients with the following risk factors: older age, on immunosuppressive treatment, DM, or dental treatment.Case Rep Neurol 2018;10:177 –180
