Temporal trends and molecular epidemiology of recently described serotype 6C of Streptococcus pneumoniae.
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.
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 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 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 کاملThe changing epidemiology of Streptococcus pneumoniae serotype 19A clonal complexes.
Streptococcus pneumoniae is a leading cause of pneumonia throughout the world and a major cause of serious invasive disease, especially in the very young and the elderly. The major virulence factor of S. pneumoniae is its polysaccharide capsule, which can be expressed as 91 different capsular serotypes [1, 2].Seven serotypes (those of high prevalence in children prior to 2000; serotype [sero]4,...
