Streptococcus pneumoniae serotype 6C: an intra- and interclonal complex comparison.
We report the annotated draft genome sequences of four serotype 6C Streptococcus pneumoniae isolates of differing genetic backgrounds. Serotype 6C isolates are increasing in prevalence and becoming progressively more resistant to antibiotics. As a result, these strains are likely to become more important in the near future.
متن کاملComparison of capsular genes of Streptococcus pneumoniae serotype 6A, 6B, 6C, and 6D isolates.
Recently, Streptococcus pneumoniae serotypes 6C and 6D have been identified. It is thought that they emerged by the replacement of wciN(β) in the capsular loci of serotypes 6A and 6B, respectively. However, their evolution has not been unveiled yet. To investigate the evolution of four serotypes of S. pneumoniae serogroup 6, four genes of the capsular polysaccharide synthesis (cps) locus, wchA,...
متن کاملOccurrence, distribution, and origins of Streptococcus pneumoniae Serotype 6C, a recently recognized serotype.
The prevalence of Streptococcus pneumoniae serotype 6C, a recently recognized serotype that cross-reacts serologically with serotype 6A, was investigated. Isolates of serotype 6A in various collections were recovered, and serotype 6C was differentiated from 6A by multiplex PCR of DNA extracts by using appropriate primers. Antimicrobial susceptibility was performed by Clinical and Laboratory Sta...
متن کاملStreptococcus pneumoniae serotype 6D cross-reacting with serotype 6A, 6B, and 6C factor sera.
We read the papers of Bratcher and Nahm (3) and Oftadeh et al. (8) with interest. Both papers reported that Streptococcus pneumoniae serotype 6D isolates react with factor antiserum specific to serotype 6C in addition to that to 6B. Pneumococcal serotype 6C, first reported in 2007, cross-reacts serologically with serotype 6A but is differentiated by a change in the wciN gene (wciN ) among the c...
متن کاملSimple, accurate, serotype-specific PCR assay to differentiate Streptococcus pneumoniae serotypes 6A, 6B, and 6C.
In this study, we developed a simple, reliable, serotype-specific PCR method to differentiate Streptococcus pneumoniae serotypes 6A, 6B, and 6C. It was more efficient and practical than the assays currently being used to identify serotypes 6A, 6B, and 6C. Of 120 selected serogroup 6 isolates from subjects with invasive (n = 101) and noninvasive (n = 19) pneumococcal disease, most of which were ...
