Figure 3From: Activated and inactivated immune responses in Caenorhabditis elegans against Photorhabdus luminescens TT01Intact P. luminescens gets to the C. elegans intestinal lumen. Nomarski DIC (A, B, E, F) or fluorescence (C, D, G, H) images of C. elegans, fed on GFP-labeled E. coli (A-D) or GFP-labeled P. luminescens (E-H) for 24 hours. Intestinal lumen was filled with ground cells when cultured on E. coli (A-D). Intestinal lumen had intact cells when nematodes were cultured on P. luminescens (E-H). Arrows indicate the terminal bulb. Anterior is left. Scale bars, 50 μm.Back to article page
