Streptococcus pneumoniae penicillin resistance is associated with the international dispersion of specifically identified strains. In Colombia, the presence and circulation of resistant strains Spain23F-1, Spain6B-2, Spain9V and Colombian23F-25 has been demonstrated in children less than 5 years old. Strain identities were established for 80 penicillin resistant S. pneumoniae isolates recovered from Colombian adult patients. Three approaches to genotypic characterization of the strains wrere used: a) chromosomal DNA was digested with Sma 1, and the products subjected to pulse-field gel electrophoresis (PFGE); b) restriction enzyme fragment comparison of the penicillin binding protein genes (pbp 1a, 2b and 2x), and c) pneumococcal surface pr...
