(A) Fluorescence micrograph of an adult hermaphrodite 30 minutes after having been placed on a lawn of Enterococcus faecalis V583::GFP. The intestinal lumen is distended and full of GFP-expressing bacteria. (B) Transmission electron micrograph of an adult hermaphrodite infected by feeding Staphylococcus aureus for 36 h. In this transversal section, the intestinal epithelium (ie, in yellow), and the gonad (g) are highlighted. The inset shows the boxed region at a higher magnification, illustrating the integrity of the plasma membrane (pm) and the dramatic loss of cytoplasmic volume in the intestinal epithelial cell. (C) Scanning electron micrograph of an adult hermaphrodite split open to reveal the large number of Bacillus thuringiensis vegetative cells colonizing the intestine. Some of the B. thuringiensis cells have been false-colored. (D) Scanning electron micrograph of an adult hermaphrodite showing multiple Drechmeria coniospora (strain JUf28) spores attached at the vulva.
