Abstract
We evaluated the genetic diversity of Bordetella pertussis, the causative agent of pertussis, within households by whole-genome sequencing. In pairwise comparisons of 23 isolates collected from 11 households, single-nucleotide polymorphism (SNP) analysis revealed extremely low SNP diversity (≤1 SNP) between isolate pairs: no SNPs were detected in 10 households and one SNP was obtained in the remaining household. This SNP was uncommon for B. pertussis and resulted in a nonsynonymous substitution (Ala303Thr) in nicotinate phosphoribosyltransferase. We demonstrated that the same strain is transmitted between household members and that B. pertussis is genomically stable during household transmission.
