Complete genome sequence of a clinical Bordetella pertussis isolate from Brazil.

There has been a resurgence in the number of pertussis cases in Brazil and around the world. Here, the genome of a clinical Bordetella pertussis strain (Bz181) that was recently isolated in Brazil is reported. Analysis of the virulence-associated genes defining the pre- and post-vaccination lineages revealed the presence of the prn2-ptxS1A-fim3B-ptxP3 allelic profile in Bz181, which is characteristic of the current pandemic lineage.
