Listeria monocytogenes<br />
Complete loss <strong>of</strong> cells in Ringer’s solution was noted by day 3, and by Day 5 in<br />
media. The drop in cell numbers was much more rapid in bacteria suspended in<br />
Ringer’s solution, falling to 2.5x10 3 cfu/ml by day 1. This compares to a <strong>bacterial</strong><br />
count <strong>of</strong> 7.9x10 4 cfu/ml in cells suspended in growth media (Fig. 3).<br />
