Figure 5.

(a) Growth of the C. coli water isolates (n = 8) after 24 hr in nonsupplemented RPMI 1640 medium (white bars) and in RPMI 1640 medium supplemented with 20 mmol/L tricarballylate (gray bars). Mean values of 3 experiments with error bars indicating SDs are shown. (b) Growth in RPMI 1640 medium supplemented with 20 mmol/L tricarballylate of the C. coli water isolates grouped together according to the clades (clade 2, n = 5; clade 3, n = 3). Mean values of isolates in each group with error bars indicating SDs are shown
