Group B meningococcal meningitis in India

The first case of infection with Group B meningococcus in India is reported. The patient was a 4-month-old boy who presented with meningitis and died within 6 h of admission. Gram stain of CSF showed meningococci and latex particle agglutination test on CSF was strongly positive for Neisseria meningitidis serogroup B. The CSF was also positive for meningococcus by polymerase chain reaction using primers NM1 and NM6, which amplify a 650 bp region of the dihydropteroate synthase (dhps) gene of N. meningitidis.
