- FIG. 1.
PFGE patterns of SmaI-digested DNA from 37 H. influenzae isolates from NP of 37 children with acute lower respiratory tract infections. Molecular typing by PFGE demonstrated that 37 H. influenzae strains from the NP had 22 PFGE patterns (A to V), without any predominant pattern. The PFGE patterns of H. influenzae types a, b, and c were different from those of the nontypeable strains.
- FIG. 2.
PFGE patterns of SmaI-digested DNA from 48 Hib isolates from the CSF of 44 children with meningitis and the NP of 4 children with acute lower respiratory tract infections. Molecular typing by PFGE demonstrated that the 44 Hib strains from the CSF had nine PFGE patterns (α to ι), with patterns α (22 isolates) and β (12 isolates) predominating. PFGE patterns of 4 Hib strains from the NP were quite different from those of 44 Hib strains from CSF.
