Serotype distribution and penicillin resistance of Streptococcus pneumoniae isolates from middle ear fluids of pediatric patients with acute otitis media in Japan

J Clin Microbiol. 2008 Nov;46(11):3808-10. doi: 10.1128/JCM.01782-08. Epub 2008 Oct 1.

Abstract

Out of 175 pneumococcal isolates from middle ear fluids, 26.3% were penicillin-resistant S. pneumoniae (PRSP). Serotypes 19F and 23F occurred most frequently among PRSP strains. The 7-valent pneumococcal conjugate vaccine (PCV) showed better coverage of PRSP strains (87.0%). The 7-valent PCV may reduce the prevalence of PRSP in Japan.
