Abstract：
:Bordetella isolates in the Saint Petersburg region have been monitored since 1998. Over the past ten years, concomitant with the increase in pertussis whole-cell vaccine coverage, the incidence of whooping cough has decreased. However, this decrease exists only for Bordetella pertussis infections, as the incidence of Bordetella parapertussis confirmed cases has remained stable, suggesting that pertussis-vaccine-induced immunity is not protective against parapertussis, as expected. B. pertussis and B. parapertussis clinical isolates were analyzed using serotyping, immunoblotting, pulsed-field gel electrophoresis of chromosomal DNA (after digestion with XbaI) and sequencing of virulence genes. The bacterial population is now similar to that observed in other European countries.
