[Comparative effectiveness of antimicrobial action of antiseptics against pathogens of chronic purulent otitis media].

Comparable antimicrobial and disinfecting action of decamethoxine and silver preparations on pathogens of chronic purulent otitis media (CPOM) was studied. The clinical isolates of staphylococci proved to be most sensitive to decamethoxine whose MBcC conformed to 16.5 micrograms/ml. The antimicrobial action on Proteus spp. and Pseudomonas aeruginosa was less pronounced. The required concentrations for bactericidal action on these pathogens were 69 and 93.5 micrograms/ml, respectively. The antimicrobial activity of the silver preparations such as poviargol, collargol and protargol was low. Depending on the microbial species, the bactericidal effect of the silver preparations was 12-235 times lower than that of decamethoxin. It was also shown that decamethoxin had a high disinfecting action on CPOM pathogens. It was noted that decamethoxin had a marked ability to increase the bactericidal action of poviargol (by 2-14 times) and its disinfecting action (by 2 times) on Proteus spp., E. coli and Ps. aeruginosa.
