Pilot study of the genetic diversity of the pneumococcal nasopharyngeal flora among children attending day care centers.

Journal of clinical microbiology - 1 Oct 2002

Abstract excerpt

A pilot study was conducted to determine the genetic diversity of multiple colonies of pneumococci recovered from 37 nasopharyngeal (NP) samples of children. A total of 239 pneumococcal isolates (typically, six to eight colonies per sample) were typed by pulsed-field gel electrophoresis (PFGE). In most NP samples (89%) the multiple colonies shared common PFGE types and serotypes. However, four samples were...
