The first report of pertactin-negative variants of Bordetella pertussis in the United States has raised questions about the role of acellular pertussis vaccines in the recent increase of pertussis cases. Our laboratory utilized a sequence-based method to identify mutations in the pertactin gene responsible for these variants and assessed vaccination status from the associated cases.
