Two groups of pulsed-field gel electrophoresis patterns among NheI- and SpeI-digested chromosomal DNA from selected serogroup X Neisseria meningitidis strains isolated in Africa. Lane: strain: 1: D93 (ST188); 2: 1970; 3: 3187; 4: 3529; 5: D5; 6: LNP13407; 7: LNP14964; 8: LNP15040; 9: 97013; 10: 97014; 11: Z9413; 12: LNP14297; 13: LNP15061; 14: BF2/97; 15: BF5/97; 16: BF1/98; 17: Z7091; 18: Z8336; 19: Z9291. Molecular weight markers were loaded in the flanking lanes as indicated (L: low-range marker; M: midrange marker); their molecular weights are indicated at the left. Characteristic band differences are indicated on the right.
