Growth of nontypable H. influenzae strains R2866 and 86-028NP in vitro . (A-C) Growth of R2866 (circles), its isogenic ∆hfq mutant derivative (squares) and the complemented ∆hfq mutant (triangles). (D-F) Growth of 86-028NP (circles) and its isogenic ∆hfq mutant derivative (squares). (A &D) Growth in 5 μg mL-1 heme (solid symbols and in hdBHI (open symbols). (B) Growth of R2866 and its derivatives in 10 μg mL-1 hemoglobin. (C) Growth of R2866 and its derivatives in 5 μg mL-1 hemoglobin. (E) Growth of 86-028NP and its derivative in 30 μg mL-1 hemoglobin. (F) Growth of 86-028NP and its derivative in 20 μg mL-1 hemoglobin. The Mann–Whitney test was used to compare make comparisons between strains over the entire 24-hour growth period. For comparisons of the wild type strains with the corresponding mutant in all concentrations of hemoglobin *P<0.0001.
