A Pediatric Case of Acute Meningitis Due to Streptococcus pneumoniae Serotype 33D
Division of Pediatric Infectious Diseases, Dr. Sami Ulus Maternity and Children’s Research and Training Hospital, Ankara, Turkey. E-mail: Streptococcus pneumoniae is a leading cause of bacterial meningitis in children. It is also responsible for bacteremia, sepsis, pneumonia, sinusitis and acute otitis media in young children worldwide. The serotypes included in the 7-valent conjugated pneumococcal vaccine (PCV7)—1, 5, 6A, 6B, 14, 19F, 23F—are those most commonly responsible for invasive pneumococcal disease (IPD) globally. Unvaccinated children are at greater risk for meningitis. The rate of non-vaccine serotypes as causes of invasive disease has increased. Although the incidence rate of IPD is highest in children aged <2 years, the rare, non-vaccine serotypes of S. pneumoniae may be responsible for acute meningitis in older, unvaccinated children. In this report, we present a pediatric case of meningitis due to S. pneumoniae serotype 33D, which has not been previously identified as a cause of IPD in those countries where PCV7 is routinely administered, including Turkey. Keywords : meningitis, child, Streptococcus pneumoniae.
