This study identifies simple sequence repeats in rmpA and rmpD/rmpC genes that mediate phase variation of the mucoid phenotype in hypervirulent Klebsiella pneumoniae, enabling adaptation to different infection niches.

This study compares genetic diversity within and between populations of Streptococcus mitis and S. pneumoniae, finding higher within-population diversity in S. mitis due to larger effective population size.
