Pulsed-field gel electrophoresis (PFGE) patterns for N. meningitidis strains isolated from a man with urethritis (case 1) and his male sex partner (case 2), Japan. PFGE was performed with the restriction enzyme NheI. Results showed the same PFGE pattern for both isolates. Salmonella enterica serovar Braenderup strain H9812 was used as the PFGE size marker strain; it was digested with Xbal and resolved by PFGE.
