FIGURE 7.
Kinetics of Bacillus anthracis Sterne 34F2 recovery from spiked Welsh soil (final concentration ∼106 CFU g-1 spores) following treatment with (A) sterile phosphate buffered saline, (B) nematodes (Caenorhabditis elegans N2), (C) germinant, and (D) germinant and nematodes (C. elegans N2). Microcosms were treated with germinants on Day 0 (300 mM L-alanine, 15 mM inosine) and Day +2 (500 mM L-alanine, 25 mM inosine) and with nematodes on Day 0 only. Solid lines represent the total viable count and dashed lines represent spore counts ± SD (n = 3).
