Cetrimide Agar + Neutralizing / Rose Bengal Caf Agar + Neutralizing dipslide is a flexible ready-to-use device with two media solidified onto a plastic support for Pseudomonas, yeasts and moulds detection for surfaces bacteriological control with inactivation of disinfectants.

TEST PROCEDURE

1. Take a slide from the refrigerator and leave it at ambient temperature for about 5 minutes.
2. Unscrew and extract the slide from its cylindrical container. Avoid any contact with the agar surface.
3. For surface monitoring, flex the cap forming a 90° angle and press each side of the slide firmly against the surface to be examined for 10 seconds. Alternatively, use a swab for sampling the area, afterwards roll the swab gently over the agar surface. For examination of liquids, hold the slide by the cap and immerse it completely into the test fluid.
4. Re-screw the slide into its tube and incubate at 36+/-1°C for 24-48 hours.

RESULTS INTERPRETATION

Count the total number of colonies on Cetrimide Agar + Neutralizing (Side 2) to obtain the total bacterial count. Total number of colonies grown on Rose Bengal CAF Agar + Neutralizing (Side 1) gives an assessment of the fungal contamination.
