(A) Adherence to monolayers of Chang conjunctival epithelial cells by strains DB117/pGJB103 (vector), DB117/HapP860295, and DB117/HapP860295 that had been preincubated with either preimmune serum, antiserum against nHapS-P860295, or antiserum against rCBDP860295 derived from GST fusion protein (FP). **, P < 0.05 compared to DB117/HapP860295 plus preimmune serum. (B) Adherence to monolayers of Chang conjunctival epithelial cells by strains DB117/pGJB103, DB117/HapN187, and DB117/HapN187 that had been preincubated with either preimmune serum, antiserum against rCBDN187 derived from GST fusion protein (FP), or antiserum against rCBDN187 isolated from inclusion bodies (IB). **, P < 0.05 compared to DB117/HapN187 plus preimmune serum. In both panels, each bar represents the means ± standard error of the means of measurements made in triplicate from a representative experiment.
