Determination of bacterial meningitis aetiology is important for decisions about vaccine policies. Cerebrospinal fluid (CSF) samples taken from patients with a clinical and laboratory diagnosis of acute bacterial meningitis were obtained from 12 health centres in 7 different geographical regions that provide health service to 32% of the population of Turkey. Streptococcus pneumoniae, Haemophilus influenzae type b (Hib) and Neisseria meningitidis were detected by PCR. During a period of one year, 408 CSF samples were included and bacterial meningitis was detected in 243 samples. N. meningitidis was detected in 56.5%, S. pneumoniae in 22.5% and Hib in 20.5% of PCR positive samples. Among N. meningitidis positive CSF samples, 42.7%, 31.1%, 2.2% and 0.7% belonged to serogroups W135, B, Y, and A, respectively. Serogroup W135 was the predominant serogroup in Turkey, except for the south coast and northwest of the country. This study showed a shift to serogroup W135 whereas serogroups A and B previously predominated. Vaccines to prevent meningococcal disease should include serogroup W135 in Turkey and possibly in other countries where many muslim pilgrims are travelling annually to the Hajj.
