Recently, 2 serologically and biochemically distinct subtypes-11Aalpha and 11Abeta-were discovered among serotype 11A isolates of Streptococcus pneumoniae. Sequence comparison of the capsular polysaccharide synthesis (cps) loci of the 2 subtypes identified disruption of the wcjE gene, a putative O-acetyltransferase, as the genetic hallmark of the 11Abeta phenotype. Directed disruption of wcjE in vitro in an 11Aalpha strain switched the strain to the 11Abeta phenotype, confirming the role played ...[more]
