Differences in genotype and virulence among four multidrug-resistant Streptococcus pneumoniae isolates belonging to the PMEN1 clone

Author: Hiller, N Luisa ; Eutsey, Rory A ; Powell, Evan ; Earl, Joshua P ; Janto, Benjamin ; Martin, Darren P ; Dawid, Suzanne ; Ahmed, Azad ; Longwell, Mark J ; Dahlgren, Margaret E Date: 2011 We report on the comparative genomics and characterization of the virulence phenotypes of four S. pneumoniae strains that belong to the multidrug resistant clone PMEN1 (Spain 23F ST81). Strains SV35-T23 and SV36-T3 were recovered in 1996 from ... Read more c b
