Phylogenetic relationships of the 82 different sequence type variations found in 518 Streptococcus pneumoniae isolates with combined erm(B)- and mef(A)-mediated macrolide resistance collected during the PROTEKT global study (1999–2003, n = 366) and the PROTEKT US study (2000–2003, n = 152) compared with the 20 PMEN (Pneumococcal Molecular Epidemiology Network [29]) clones.
