Density of colonizing bacteria in the intestine of C. elegans strains and their survival. Number (cfu) of E. coli OP50 (Panel A) or S. typhimurium SL1344 (Panel C) within the intestine of N2 (wild type), daf-2 and phm-2 single mutant, and daf-2;phm-2 double mutant C. elegans strains. Panel B) Survival of same strains when grown on lawns of E. coli OP50 or S. typhimurium SL1344 (Panel D).
