Table 2 Distribution of pneumococcal serotypes which caused meningitis by age group

From: An outbreak of pneumococcal meningitis among older children (≥5 years) and adults after the implementation of an infant vaccination programme with the 13-valent pneumococcal conjugate vaccine in Ghana

  1. aThese CSF had a Ct value >32 and <36 for pneumococcal detection which is above the threshold for molecular serotyping
  2. bThe pneumococci could not be serotyped using molecular techniques which detect a limited panel of serotypes
  3. cThe CSF specimens and isolates were not available for serotyping
