We used multilocus variable-number tandem repeat analysis and multiple antigen sequence typing to characterize isolates of Bordetella pertussis strains circulating in Denmark during periods with and without pertussis vaccination coverage. Our results show substantial shifts in the B. pertussis population over time and a reduction in genetic diversity.
View Article and Find Full Text PDFA PCR assay for the detection of Bordetella pertussis and Bordetella parapertussis was compared with the conventional culture method under routine laboratory conditions. Detection of B. pertussis was based on the amplification of a section of the IS481 insertion sequence and confirmation of positive results was based on a sequence of the pertussis toxin promoter region.
