To better understand extensively drug resistant Streptococcus pneumoniae, we assessed clinical and microbiological characteristics of 5 extensively drug-resistant pneumococcal isolates. We concluded that long-term care facility residents who had undergone tracheostomy might be reservoirs of these pneumococci; 13- and 23-valent pneumococcal vaccines should be considered for high-risk persons; and antimicrobial drugs should be used judiciously.

Keywords: South Korea; Streptococcus pneumoniae; antimicrobial drug resistance; bacteria; extensively drug-resistant.


Dendrogram of pulsed-field gel electrophoresis patterns showing the genetic relatedness of extensively drug-resistant pneumococcal isolates from patients in South Korea, 2011–2012 (including SMC 1205–093, previously reported in 2012). The corresponding serotype and sequence type (ST) for each isolate are listed on the right side of the dendrogram. SMC, Samsung Medical Center.
