Inactivation of Legionella pneumophila by hypochlorite and an organic chloramine.
The susceptibility of a strain of Legionella pneumophila to disinfection by an organic halamine, free chlorine, and a mixture of the organic halamine and free chlorine was assessed. The organic halamine was found to have superior stability in solution and to exhibit adequate disinfectant potential over a period of 1 month of repeated reinoculations of fresh bacteria. The combined halamine exhib...
متن کاملRemoval of sodium channel inactivation in squid axon by the oxidant chloramine-T
We have investigated the effects of a mild oxidant, chloramine-T(CT), on the sodium and potassium currents of squid axons under voltage-clamp conditions. Sodium channel inactivation of squid giant axons can be completely removed by CT at neutral pH. Internal and external CT treatment are both effective. CT apparently removes inactivation in an irreversible, all-or-none manner. The activation pr...
متن کاملMechanisms of inactivation of poliovirus by chlorine dioxide and iodine.
Chlorine dioxide and iodine inactivated poliovirus more efficiently at pH 10.0 than at pH 6.0. Sedimentation analyses of viruses inactivated by chlorine dioxide and iodine at pH 10.9 showed that viral RNA separated from the capsids, resulting in the conversion of virions from 156S structures to 80S particles. The RNAs release from both chlorine dioxide- and iodine-inactivated viruses cosediment...
متن کاملOxidation of Some Aliphatic Aldehydes by Chloramine-t
Kinetic studies on the oxidation of acetaldehyde, propionaldehyde, nand tso-butyraldehyde have been made using diloramine-T as an oxidising agent in an alkaline medium. The reactions followed almost identical kinetics being first order with respect to both aldehyde and chloramine-T. The order with respect to alkali has been found to be almost equal to unity (0.8 to 0.90) . Effect of an increase...
متن کاملEffect of inactivation by hydroxylamine on early functions of poliovirus.
Evidence is presented that poliovirus particles with a single lethal hit by hydroxylamine do not induce in host cells either inhibition of cellular protein synthesis or viral ribonucleic acid (RNA) replication. The RNA of these viruses is not replicated even if the cells are simultaneously infected with both active and inactivated viruses. The damaged viral RNA seems to have lost both its templ...
