Abstract：
:The effect of subinhibitory concentrations (subMICs) of new organic ammonium salts of four homologous series of alkylammonium bromides (32 compounds) was determined with respect to the induction of lysogenic strain prophage, influence of permeability reactions in a rabbit skin test and cytotoxic changes of monolayers of Vero cells. The culture filtrates were prepared by 1-d cultivation of Salmonella typhimurium in a synthetic culture medium under conditions of intensive aeration at 37 degrees C after addition of subinhibitory concentrations of organic ammonium salts. The results showed that substances of the homologous series of 2-(10-undecenoyloxy)ethyl-alkyldimethylammonium bromides were characterized by a prophage-inducing effect in lysogenic strain cells. The induction of prophage raised with rising concentrations of subMICs of the substances, and its titer in the culture filtrates was mostly 4.10(6) PFU/mL. Substances C3, C9 and C12 of the same homologous series had the strongest effect on the permeability reaction in rabbit skin in 1/2 MICs. One-half MICs of four substances (B14, C3, C12, C14) and 1/4 MICs of substance A16 influenced cytotoxic changes on Vero cells, the other substances were ineffective.
