This study reports the case of a 10-month-old boy with pneumococcal meningitis caused by the non-vaccine serotype (NVT), 15A.
Gram-positive cocci (GPC) were detected from the blood and treated with antimicrobial drugs, while otitis media was suspected, and the same GPC was confirmed by adding the cerebrospinal fluid test. Treatment with ceftriaxone and vancomycin was started for suspected pneumococcal meningitis. Afterwards, pneumococci were detected from the blood and cerebrospinal fluid. In addition, the susceptibility test revealed that the pneumococci were resistant to penicillin and meropenem.
Although pneumococcal meningitis has decreased with the introduction of conjugated pneumococcal vaccine, pneumococcal meningitis caused by NVT tends to increase, and meningitis, which is still a severe infection, should not be overlooked. Furthermore, as in this case, attention needs to be paid to detecting the trend of a high resistance rate in serotype 15A to penicillin and meropenem.
