Figure 3

Dendrogram analysis of 27 pulsed-field gel electrophoresis profiles of Bordetella pertussis isolates circulating in China during 1953–2005. The unweighted pair group method with arithmetic mean with 1% band tolerance and 1% optimization settings was used as the clustering method. * indicates international reference strains (17,23); † indicates vaccine strains from China. Vaccine strains P3s10 and CS represent BpCHR6, and vaccine strain 18530 represents BpFINR13.
