Microscopic images of the C. elegans exposed to Serratia marcescens for 24 h at 20 °C were presented. (A) Wild-type C. elegans fed with OP50 showed normal eggs with normal physiology. (B) In disparity, Serratia marcescens challenged nematodes exposed presented severe physiological defects such as distended pharynx and intestinal colonization (C,D) nematodes that was treated with quercetin showing reduced colonization and physiological damage compared to the control at ¼ MIC and ½ MIC concentration.
