Each of the three experimental groups (MB-Irradiated, MB-Shielded and Untreated-Irradiated) was assayed in duplicate. Results are expressed as log10 reduction in colony forming units (cfu) compared to the Untreated-Irradiated group. In each case, there was complete eradication of culturable organisms in irradiated samples treated with MB.
