BACKGROUND & OBJECTIVES Cetrimide is a monocationic surfactant, commonly used for disinfection of hospital floors, equipments, for cleansing of burns and wounds, hand wash, etc. We evaluated whether antibiotic resistant (AR) Escherichia coli isolates from hospital settings (nosocomial pathogens) show any evidence of significant reduction in their susceptibility to cetrimide. Also the response o...

Significant differences were found between Dettol (chloroxylenol) agar, nalidixic acid-cetrimide agar, and two other cetrimide-containing agars used for the isolation of small numbers of pseudomonads.

Williams, Clayton-Cooper, Faulkner, and Thomas (1944) drew attention to the fact that Pseudomonas pyocyanea may survive and even multiply in solutions of cetrimide (cetyl-trimethyl-ammonium-bromide). The use of this compound in selective media for the identification of Ps. pyocyanea was suggested by Harper and Cawston (1945), who recommended a concentration of 1 % in nutrient agar. This medium,...

Background: Antiseptics are commonly used for personal hygiene in Taiwan. We have previously reported a series of ichthyosiform irritant contact dermatitis induced by cetrimide-containing antiseptics. Objectives: To report a new series of antiseptics-induced ichthyosiform irritant contact dermatitis and bring attention to the potential irritation effects of antiseptics. Methods: We reviewed the...

A cabinet for detecting the fluorescence of cultures on agar media is described. The use of fluorescence as a criterion for detection of Ps. pyocyanea is compared with that of the oxidase reaction. From a series of patients with burns, all colonies of Gram-negative bacilli which gave a positive oxidase reaction yielded fluorescent subcultures on 0.03% cetrimide agar; all fluorescent cultures on...

Osmotically balanced solutions of glucose (0.5-300 mM) and sodium chloride, containing cetrimonium bromide (cetrimide, 0.8-4.1 mM), were instilled into the jejunum, ileum and colon of anaesthetized rats. Net transport of glucose, sodium and potassium was studied by their disappearance from, or accumulation into the intestinal lumen during 15 min incubation. Cetrimide caused the following shifts...

This study evaluated the influence of the addition of cetrimide and polypropylene glycol to sodium hypochlorite (NaOCl) on its capacity to dissolve pulp tissue. Bovine pulp fragments with standardized weight and volume were immersed for 5, 15 and 30 min in 2 mL of NaOCl and Hypoclean (NaOCl added with cetrimide and polypropylene glycol) solutions at 5.25%, 2.5%, 1%, 0.5% and 0.25% and afterward...

cream applied locally or used for holding sterile instruments might be conveying the infective agent. Soap solution, cetrimide, " dettol" and calamine lotion are commonly dispensed in large corked or stoppered bottles which are sometimes not replaced for many days, and during that time they are frequently opened. Contamination of such bottles is likely, and the survival or multiplication of som...
