December 2024
Background: The prevalence of serotypes and antimicrobial resistance of was characterized among children thirteen years after the licensure of the pneumococcal conjugate vaccine (PCV) in Japan.
Methods: A total of 353 pneumococcal isolates were collected from Japanese children between March and July 2023. All the isolates were serotyped using genetic methods and tested for susceptibility to 14 antimicrobial agents.
Article Synopsis
- Ten years after the PCV vaccine was introduced in Japan, non-PCV13 serotypes were found in 94.0% of pediatric pneumococcal isolates, while non-PCV20 serotypes were at 73.7%.
- The study identified the most common non-PCV serotypes as 15A, 35B, and 23A.
- These predominant strains were largely multidrug-resistant, with over 80.5% showing non-susceptibility to penicillin.
