Abstract excerpt
Antigenic divergence has been found between Bordetella pertussis vaccine strains and circulating strains in several countries. In the present study, we analyzed B. pertussis isolates collected in Japan from 1988 to 2001 using pulsed-field gel electrophoresis (PFGE) and sequencing of two virulence-associated proteins. The 107 isolates were classified into three major groups by PFGE analysis; 87 (81%) were type A,...
