Figure 1
Structural analysis of C. elegans intestines and detailed pictures of endophytic bacteria obtained via TEM.
Photographs of C. elegans originating from soil. (A) Light microscopy showed that the worms were alive and that their intestines were normal after feeding on E. coli for 48 h; (B) Light microscopy showed that the worms were dead and their intestines were disorganized after feeding on B. nematocida strain B16g-1 for 4 h prior to transfer to E. coli plates for 24 h; (C) Cross-section of uninfected worms (4000-fold amplification); (D) Cross-section of 24-h-infected worms (4000-fold amplification). Symbiotic microbiota are indicated with white arrows in (C,D).
