A report of Streptococcus pneumoniae serotype 6D in Europe
نویسندگان
چکیده
Serotype 6D of Streptococcus pneumoniae has been reported in Asia and the Fijian islands among nasopharyngeal carriage isolates. We now report a 6D isolate from a Finnish adult with invasive pneumococcal disease. Interestingly, the Finnish isolate and Asian isolate capsule gene loci are almost identical.

Validation of factor 6d antiserum for serotyping Streptococcus pneumoniae serotype 6C.
Factor 6d antiserum reacts with the new Streptococcus pneumoniae serotype 6C. Serogroup 6 isolates, consisting of 49 6A, 42 6B and 98 6C strains from the United States and Israel, serotyped in parallel by PCR and capsular swelling methods, were all identified correctly. The new factor 6d antiserum accurately identifies serotype 6C.
متن کاملFirst report of putative Streptococcus pneumoniae serotype 6D among nasopharyngeal isolates from Fijian children.
BACKGROUND A putative Streptococcus pneumoniae serotype, 6D, resulting from the introduction of wciN(beta) into serotype 6B has been proposed. METHODS We studied 98 unique serogroup 6 isolates from Fijian children, two-thirds of whom had received at least 1 dose of 7-valent pneumococcal conjugate vaccine, and 51 invasive isolates from Australian children. We used a polymerase chain reaction (...
متن کاملFirst report of Streptococcus pneumoniae serotype 6D in South America.
Streptococcus pneumoniae includes the two serotypes 6A and 6B as well as two recently discovered serotypes, 6C and 6D, in which the wciN gene is replaced by wciN within the cps locus. Serotype 6D occurrence in Asia (2, 4), the Fiji islands (5) and Europe (7, 9) has recently been reported. To our knowledge, we describe here the first description of serotype 6D isolates identified within the Amer...
متن کاملMultidrug-resistant Streptococcus pneumoniae serotype 6D clones in South Korea.
To investigate the characteristics of main Streptococcus pneumoniae clones of serotype 6D (ST282 and ST3171) in South Korea, antimicrobial susceptibility testing was performed, and 11 genes around the cps locus were sequenced on ST282(6D), ST3171(6D), and ST81(6A) isolates. The antimicrobial susceptibility patterns were very similar between clones belonging to the same clonal complex, ST81(6A) ...
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,...
