[The synergistic action of quaternary ammonium derivatives and inhibitors of nitrate reduction in respect to Pseudomonas aeruginosa].

It was revealed that ability of zink chloride, copper sulphate, aluminium nitrate and sodium chloride to inhibit the nitrate reduction of Pseudomonas correlated with their potentiating influence on the antimicrobial activity of decamethoxin, a quaternary ammonium derivative. So, doses of zink chloride (0.01-0.
