✦ Synopsis


bromide and naturally resistant to various quaternary ammonium compounds with alkyl chain lengths of C12-Cl8, was also used. Proteus vulgaris NCTC 4635 was used for determination of laboratory resistance to 1 as a strain with extremely high ability to acquire resistance to quaternaries.

Microbiohgical techniques

The antibacterial activity of quaternary ammonium chlorides was determined using minimum bactericidal concentration (MBC) procedure in nutrient broth. Development of laboratory resistance was investigated using training procedure in nutrient broth containing increasing concentrations of quaternaries. ~~ [ (alkylthio)methyl] -C&13 la pyridinium CaH I 7 lb CIUH21 lc C12H25 Id alkylpyridinium 2a 2b 3 alkylbenzyldimethylammonium Cl(iH33 4 I-methyl-3-[(alkylthio)-methyl1imidazolium
