Figure. Pulsed-field gel electrophoresis patterns of ApaI-digested chromosomal DNAs of Haemophilus influenzae isolates. Lanes 1–5, H. influenzae type e (Hie) isolates, respectively, from patient nos. 1–5; lane 6, H. influenzae type b (Hib) strain belonging to one of the subclones endemic in Italy (9); M, λ ladder pulsed-field gel marker with molecular weights indicated in kilobases (kb) at the right. The isolates in lanes 3, 4, and 5 showed indistinguishable profiles (pattern 1); the isolate in lane 1 was closely related to pattern 1 (pattern 1a), whereas the isolate in lane 2 was clearly different from pattern 1 (pattern 2). All Hie isolates were unrelated to the Hib strain.
