Influences of type IV pili, the capsule, and Knh on K. kingae adherence. The adherence of K. kingae KK03 (WT) and the pilA1, knh, ctrA, pilA1/knh, knh/ctrA, pilA1/ctrA, and pilA1/ctrA/knh mutant strains to Chang human epithelial cells was measured. Adherence assays were conducted in triplicate. Error bars indicate standard errors of the means. Statistical analyses were performed by using the unpaired t test to compare the adherence levels of two strains as follows: P < 0.05 (*) for pilA1/ctrA versus pilA1 and for pilA1/ctrA/knh versus pilA1/ctrA.
