Figure 4

Ultra-structure of NTHi mutants co-cultured with EpiAirway tissues. EpiAirway tissues were infected with the wild type (A), ΔvapBC-1 (B), ΔvapXD (C), or ΔvapBC-1 ΔvapXD (D) strains at ~107 colony forming units (CFU) per insert. On day 5 after infection, the tissues were fixed and sectioned for transmission electron microscopy. No significant difference in morphology was observed for any of the mutants.
