Serotype distribution and antimicrobial resistance of Streptococcus pneumoniae in the Philippines, 2012–2018

Objective: Data are scarce on the prevailing Streptococcus pneumoniae serotypes in Philippines, including relative antimicrobial resistance (AMR) of these bacteria. This study is designed to fill that gap by describing serotype distribution and AMR S. Philippines from 2012 2018. Methodology: isolates clinical specimens were collected through Philippine Department Health Antimicrobial Resistance Surveillance Program 1 January 31 December Identification susceptibility testing (AST) performed using conventional automated methods (Vitek2 Compact Automated Machine). AST for penicillin, erythromycin, co-trimoxazole, ceftriaxone levofloxacin was done following Clinical Laboratory Standard Institute recommendations. Serotyping slide agglutination Denka Seiken method. Results: From a total 307 pneumoniae, 32 identified; most frequently occurring 1, 3, 5, 4, 18, 19A, 6B, 15 14. Many (n=113, 36.53%) those aged <5 years. Pneumococcal conjugate vaccine (PCV) coverage as follows: PCV7 (32.69%), PCV10 (54.16%) PCV13 (69.23%). The overall invasive low. Penicillin-resistant 14, 19, 24, 15, 6 32. Discussion: With inclusion National Immunization Program, continued monitoring needed guide disease control measures.
