Figure 6. Cryptococcal host interactions are highly sensitive to capsule induction.

Upper panels, India ink staining of fungal cells at 24 h without (A) or with (B) capsule induction. Panel C, standard assay performed with cells grown for the indicated times in the conditions shown. Mean and standard deviation are plotted for indices of adherence. All samples were grown at 37°C in either room air (white bars) or 5% CO₂ (blue bars).
