The Antibacterial Activity of a New Chloroxylenol Preparation Containing Ethylenediamine Tetraacetic Acid

Abstract

A new chloroxylenol preparation (DC) containing ethylenediamine tetraacetic acid (EDTA). has been shown to be an effective bactericidal agent against various Gram positive and Gram negative bacteria. It possessed significant and rapid activity against two strains of Pseudomonas aeruginosa as well as against chlorhexidine‐and chloroxylenol‐resistant derivatives of these strains. DC showed high activity at 20° and 30 °C, and (unlike chlorhexidine) when prepared in hard water or when used in the presence of organic matter. Repeated challenge testing at 20 °C of DC (but not of chloroxylenol) with Ps. aeuruginosa indicated that contamination of DC will not prove to be a problem in practice and that the activity of solutions will be retained during storage.

Chemical Analyses, Antimicrobial and Antioxidant Activities of Extracts from Cola nitida Seed

“…26, 27 The bacteria were grown in a nutrient broth before use, while the fungi were grown on potato dextrose agar medium until they sporulated, at which time they were harvested. The standardized bacteria suspension was spread on Muller-Hinton agar and allowed to set.…”

“…The sensitivity testing of the extracts were determined using agarwell diffusion method (Russell and Furr, 1977;Irobi et al, 1996). The MIC of the extracts was also determined using a two-fold dilutions method (Russell and Furr, 1977).…”

“…The MIC of the extracts was also determined using a two-fold dilutions method (Russell and Furr, 1977). The bacterial isolates were first grown in nutrient broth for 18 h before use.…”
