FIG. 4.

Coaggregation of L. lactis expressing SspB with C. albicans hyphae. (B to I) FITC-labeled L. lactis MG1363 (Ll control) or L. lactis MG1363(pUB1000-sspB) (LlSspB) was incubated in suspension with hypha-forming cells of C. albicans NGY152 (CaWT) or the 1843 als3Δ/als3Δ mutant (CaΔALS3). Aggregates were visualized by light or fluorescence microscopy. (A) Percentages of hyphae with attached bacteria were calculated on the basis of bacterial binding levels, as described in the legend to Fig. 2. The data are means ± standard errors (SE) from 4 independent experiments (*, P < 0.05).
