clonal relationship between u.s. and french serotype v group b streptococcus isolates.we examined the genetic diversity of serotype v group b streptococcus (gbs) isolates in the paris area and compared them with the predominant american serotype v clone. pulsed-field gel electrophoresis yielded 11 patterns for 64 french gbs. one pattern was obtained with 60% of the isolates tested and was indistinguishable from that of the predominant american clone.200111724875

[role of group b streptococcus serotype v in materno-fetal infections].the classification of serogroup b streptococci in serotype is based on the structural differences of capsular polysaccharides and on presence or absence of a protein c antigen. they are classified as ia, ia/c, ib/c, ii, ii/c, iii, iv and v. the serotype v, unknown in 1970, seems emerging, and is placed in third position of frequency in some american studies. we have therefore decided to evaluate its frequency in paris.19979488740
epidemiology of pediatric community-acquired bloodstream infections in a children hospital in paris, france, 2001 to 2008.in 2001 to 2008, we documented 483 cases of pediatric community-acquired bacteremia mostly because of streptococcus agalactiae (< 4 days), escherichia coli (4 days to 3 months), pneumococci (3 months to 5 years), and staphylococcus aureus (> 5 years). pneumococcal conjugate vaccination affected the serotype distribution of pneumococcal bacteremia but not its frequency. serotype 19a represented 12% and 22% of pneumococci in the prevaccine and vaccine periods, respectively.201020159378
