Contamination of Cetrimide and Other Fluids with Pseudomonas pyocyanea

Contamination of cetrimide and other fluids with Pseudomonas pyocyanea.

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...

The use of a new cetrimide product in a selective medium for Pseudomonas pyocyanea.

A selective medium containing 0.1 % cetrimide in nutrient agar has been used here during the past four years for the routine identification of Ps. pyocyanea in burns (Lowbury, 1951). This medium, a modification of those previously described by Harper and Cawston (1945) and by Hood (1948), has proved convenient and efficient. In October, 1953, the manufacturers announced the production of a modi...

A Bacteriophage for Pseudomonas pyocyanea (Pseudomonas aeruginosa).

Pseudomonas Pyocyanea and the Arginine Dihydrolase System.

Non-pigmented strains of Pseudomonas pyocyanea occur frequently and this organism has only limited activity in conventional biochemical tests; 50 strains were tested for the presence of arginine dihydrolase and found positive whereas only Salmonella sp. and Enterobacter sp. among other Gram-negative species were positive. The test for arginine dihydrolase is rapid and simple and suitable for ro...

Use of an improved cetrimide agar medium and other culture methods for Pseudomonas aeruginosa.

In a comparison of two selective media for Ps. aeruginosa containing 0.03% cetrimide, stronger fluorescence was obtained from growth on the medium prepared with King's medium B as the base (CTA 2); although Ps. aeruginosa was not isolated more frequently from burns on this medium than from cetrimide agar made with a Lemco base (CTA 1), results were easier to assess and there were fewer cases of...
