A comparative study on the efficacyofperacetic acid and sodium hypochlorite in inactivating resistant stages of microorganisms such as Cryp-tosporidium, Giardia and Cl. perfingens was carried out. Furthermore the evaluation of the potential reciprocal correlation among the concentrations of the organisms was performed. The results obtained indicate that, at the same experimental conditions, peracetic acid and sodium hypochlorite have nearly similar reduction power against the resistant stages of Giardia and Cl. perfringens. Both the oxidants are instead less efficientintheabatementof Cryptosporidium oocysts. Findings have also confirmedourpreviousstudiesontheabsenceofassociationbetweenClostridium and the protozoa.
