DNA sequencing of the entire H. influenzae genomewas completed in 1995. When DNA from the nonpathogenic strain H. influenzae Rd was compared tothat of the pathogenic b strain, eight genes of the fimbrial gene cluster (located between the purE andpepN genes) involved in adhesion of bacteria to hostcells were completely missing from the nonpathogenic strain. What effect would this deletion have oncotransformation of purE and pepN genes using DNAisolated from the nonpathogenic versus the pathogenic strain?
