Abstract
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.
Highlights
To better understand extensively drug resistant Streptococcus pneumoniae, we assessed clinical and microbiological characteristics of 5 extensively drug-resistant pneumococcal isolates
The Study We reviewed the database of the clinical microbiology laboratory at Samsung Medical Center (SMC, Seoul, South Korea) for XDR S. pneumoniae isolates obtained during 2011–2012
Four of 5 XDR S. pneumoniae isolates had been isolated from respiratory tract specimens, and 1 isolate had been recovered from blood (Table 1, Appendix, wwwnc.cdc.gov/EID/article/20/5/13-1371-T1.htm)
Summary
To better understand extensively drug resistant Streptococcus pneumoniae, we assessed clinical and microbiological characteristics of 5 extensively drug-resistant pneumococcal isolates. The Study We reviewed the database of the clinical microbiology laboratory at Samsung Medical Center (SMC, Seoul, South Korea) for XDR S. pneumoniae isolates obtained during 2011–2012. XDR S. pneumoniae was defined as nonsusceptibility to at least 1 agent in all antibacterial drug categories except vancomycin and linezolid.
