[Microbicidal effect of Lautercide, a new disinfectant].
The authors tested the effect of a new disinfectant Lautericide produced by Qualichem Co. Neratovice which contains as the active agent acetate amine of coconut acid. For experiments standard methods were used and standard strains for testing of the following microbial strains: St. aureus, E. coli, Ps. aeruginosa, Proteus vulgaris, Serratia marcescens, Candida albicans, spores of Bacillus subtilis, M. tuberculosis, M. fortuitum, M. avium. As a model virus E. coli bacteriophage OX 174 was used. In concentrations from 0.04% to 0.5% and exposures from 2 to 10 minutes Lautercide exerted a bactericidal and fungicidal action. On spores of B. subtilis the preparation was ineffective even in a 10% concentration and 32-minute exposure. Devitalization of mycobacteria occurred after 15 min. action of Lautercide on M. tuberculosis and M. fortuitum, in M. avium in a 10% concentration in 60 min. Lautercide is ineffective against small resistant viruses without an integument. It is recommended to use Lautercide in a 1% aqueous solution for a one-stage disinfection combined with cleaning in the health services, veterinary medicine and in the field of communal hygiene. Before cleaning objects contaminated with infectious material, 5% Lautercide with 30 min. exposure is recommended. In disinfection of objects contaminated with mycobacteria it is recommended to use a 5% solution with 10-minute exposure for M. tuberculosis and M. fortuitum and a 10% solution for M. avium with 60-minute exposure.
