Microscopic analysis of inter-species interaction. Examples of fluorescent microscopic images and quantitative enumeration of the interaction between S. aureus NCTC8325-4GFP and C. albicans strains. (A) S. aureus with C. albicans SC5314 hyphae. (B) S. aureus with C. albicans MB1 hyphae. Scale bar corresponds with 10 μm. (C) number of S. aureus NCTC8325-4GFP adhering per 10 μm length of different regions of C. albicans hyphae and yeast cells. Error bars represent SD over three experiments with separately cultured organisms and involving 30 hyphae per bacterium-fungus pair.
