Abstract:  3-Substituted and 2,3-disubstituted benzothiazolium salts were prepared by treatment of benzothiazole or 2-aIkylbenzothiazoles with reactive halides or dialkyl sulfates. The antibacterial, antifungal, and antiprotozoal activity of the salts is reported. 3-Ethyl-, 3-propyI-, and 3-butylbenzothiazolium salts were found to be active against such strains of Staphylococcus aureus which are resistant to some antibiotics. Several compounds showed good growth-stimulating and/or inhibiting activity.
