Figure 1. Wild type (N2) worms growing on E. coli OP50 and Salmonella Typhimurium MST1.

As previously described ( Palominos et al., 2017 ), the exposure to bacterial pathogens for two consecutive generations cause that a percentage of C. elegans population enter diapause, forming the dauer larvae (arrowheads). Adults can be seen in both conditions (arrows). Scale bars = 500 μm.
