Figure 2. . A, restriction fragment length polymorphism (RFLP) analysis of Neisseria meningitidis serogroup C strains generated by pulsed-field gel electrophoresis (PFGE) by using the Spe I restriction endonuclease. The strain CDC-413 was used as a control for the PFGE. B, dendogram analysis generated from “A.” Percent identity is shown at the top. The RFLP pattern designation is shown on the right. RFLP patterns not underlined were seen from January 1997 to November 1999. Underlined RFLP patterns were seen from December 1999 to April 2001. The dashed line indicates 85% identity. A 1% tolerance was used to generate the dendogram.
