Genomic patterns of nasopharyngeal H. influenza isolates by PFGE. Randomly analysed strains PFGE pattern was assessed by a CHEF-DR III software. As seen in Fig. 1 despite different antibiotic resistance pattern of ampicillin resistant isolates, these strains clustered in a similar clone. This also applies in the case of strains resistant and susceptible to chloramphenicol
