title: Temporal trends and molecular epidemiology of recently described serotype 6C of Streptococcus pneumoniae.
abstract: We studied the epidemiology of the recently described serotype 6C of Streptococcus pneumoniae among a collection of carriage isolates recovered between 1996 and 2007 in Portugal. Of 4,064 isolates, 106 (2.6%) were of serotype 6C, 17.9% of which were multidrug resistant. The strains were genetically diverse.
