title: Expression of a C terminally truncated form of pertussis toxin S1 subunit effectively induces protection against pertussis toxin following DNA-based immunization.
abstract: Four plasmids encoding different C terminally and N terminally truncated pertussis toxin S1 subunits of Bordetella pertussis were constructed and tested for inducibility of protection against pertussis toxin in mice after DNA-based immunization. The region encoding an N-terminal 180-amino-acid fragment of the S1 subunit had the most potent ability to induce protective immunity.
