Figure 1

For each organism, three experimental groups (MB-Irradiated, MB-Shielded and Untreated-Irradiated) were assayed in duplicate in three separate experiments. Results are expressed as the mean ± S.D. of log10 reduction in colony forming units (cfu) compared to the Untreated-Irradiated group. The absolute number of organisms in untreated groups = 1–3 ×107 cfu/ml.
