Interactions of GBS or lactococci expressing BspA with C. albicans. A, GBS NEM316 cells; B, L. lactis pMSP vector control; or C, L. lactis pMSP.bspA⁺. L. lactis strains were cultured for 16 h in the absence (uninduced) or presence of 100 ng/ml nisin to induce BspA expression. GBS or L. lactis cells were FITC-labeled and incubated in suspension with hypha-forming cells of C. albicans stained with calcofluor white. Aggregates were visualized by fluorescence microscopy. Scale bars, 20 μm.
