Literature review—efficacy of various disinfectants against Legionella in water systems

Efficacy of Colloidal Silver-Hydrogen Peroxide and 2-Bromo-2-nitroporopane-1,3-diol Compounds Against Different Serogroups of Legionella pneumophila Strains

“…In general, oxidizing biocides were found to be more effective than non-oxidizing ones against legionellae [5,16,17]. In the present study oxidizing biocide (CSHP) was found more effective than non-oxidizing biocide (BNPD) in terms of contact times, log reductions and recommended concentrations.…”

“…Contaminated water systems with legionellae must be eradicated by alternative biocides without delay [5,6]. Various oxidizing and non-oxidizing agents have been investigated for legionellae decontamination of water systems [2][3][4][5][6][19][20][21][22].…”

“…Various oxidizing and non-oxidizing agents have been investigated for legionellae decontamination of water systems [2][3][4][5][6][19][20][21][22]. In this sense, CSHP and BNPD were examined as an example for oxidizing and non-oxidizing agents, respectively, in view of bactericidal action against different serogroups of L. pneumophila strains.…”

“…Since several factors such as bacterial strains and the background conditions in the water system (e.g. pH, temperature, and organic and inorganic constituents' levels) affect the efficiency of a biocide against bacteria, results which were found as effective should be tested under field trial conditions [5,18,25].…”

“…Well-known sources of the legionellosis are frequently contaminated cooling tower waters or potable waters. Irrefutable studies demonstrate that the overall prevention strategy against these bacteria in cooling towers depends on regular maintenance and cleaning of the towers in conjunction with chemical biocide control [1][2][3][4][5]. A number of different oxidizing and nonoxidizing agents biocides have been examined to determine their effectiveness against these bacteria, in vitro [1,[6][7][8].…”
