Figure 5. Infection of C. elegans by B. anthracis-gfp in presence of B. thuringiensis expressing Cry5B spores (non-gfp) and B. anthracis-gfp spores.

Figure 5

(A) Transmitted-light view of the worm cuticle filled with vegetative and sporulated Bacillus. (B) View of the same worm using the fluorescence light: rod-shaped bacteria expressing GFP are visible, indicating that B. anthracis is capable of infecting C. elegans in presence of Cry5B expressing-B. thuringiensis. In this animal and all similar animals examined, the vast majority of bacteria inside the nematode cuticle were GFP positive. Scale bar is 50 µm.
