Figure 2. Salmonella Typhimurium DT104 colonization in C. elegans intestine is enhanced due to MDR genes.

L1 stage N2 worms were exposed to DT104 (--●--) and SNS12 (--■--), and the extent of colonization was determined every 24 hours. Each data point represents the colony forming unit per worm (CFU worm^-1) from a pool of 10 infected worms. Horizontal bar indicates the cumulative geometric mean of three independent experiments.
