Mean nontypeable Haemophilus influenzae (NTHI) biomass scores for each bulla after transcutaneous immunization (TCI) following a therapeutic regimen, based on blinded evaluation and ranked on a 0 to 4+ scale of relative residual biomass. *Statistically significant compared with receipt of dmLT alone (P<0.05). Receipt of LB1, rsPilA, or chimV4, admixed with dmLT, resulted in significantly enhanced resolution of NTHI biofilms established within the middle ear space. dmLT, double mutant of E. coli heat-labile enterotoxin; rsPilA, recombinant soluble PilA.
