Product catalog summary
CHROMagarTM Cronobacter Instructions for Use

Medium Purpose: CHROMagarTM Cronobacter is a chromogenic agar designed for isolating Cronobacter spp. in food, animal feed, and environmental samples, compliant with ISO 22964 standards.

Inoculation Procedure: Samples can be directly streaked on the plate or after pre-enrichment and enrichment as per ISO 22964. Plates should be at room temperature if refrigerated. Inoculate with a loopful (10µl) from an enrichment broth and incubate at 41.5°C ± 1°C for 24h ± 2h under aerobic conditions.

Preparation: For 1L of medium, disperse 32.7g of powder in 1L of purified water, stir until thickened, heat to 121°C for 15 minutes, cool to 47-50°C, pour into sterile Petri dishes, and let solidify.

Composition: The medium consists of agar, casein peptone, yeast extract, NaCl, and other components, totaling 32.7g/L. The final media pH is 7.3 ± 0.2.

Storage: Store in the dark at 15-30°C. Prepared plates can be kept at room temperature for one day or refrigerated for up to one month if protected from light and dehydration.

Interpretation: Cronobacter spp. appear as green to blue colonies. Other gram-negative bacteria may appear colorless, clear green, black, or yellow, while gram-positive bacteria are inhibited.

Performance & Limitations: Definitive identification requires additional tests like ONPG and Indole tests. Quality control should be performed using ATCC strains.

Warnings: Do not use plates showing contamination or deterioration. Use only by trained personnel. Changes in procedure or storage conditions may affect results.

Disposal: Sterilize or dispose of contaminated materials according to local regulations. Plates can be autoclaved at 121°C for at least 20 minutes.

References: For scientific publications, refer to the CHROMagar website.

Product Overview: CHROMagar Cronobacter is a chromogenic medium designed for the isolation of Cronobacter spp. in food, animal feed, and environmental samples, compliant with ISO 22964 standards.

Specifications: The medium consists of a single base with a composition of 32.7 g/L, including agar, casein peptone, yeast extract, NaCl, and other components. The final pH is 7.3 ± 0.2. It should be stored at 15-30°C, protected from moisture and light.

Preparation Procedure: Dissolve 32.7 g of the base in 1 L of distilled water, heat to 121°C for 15 minutes, cool to 47-50°C, and pour into sterile Petri dishes. Allow to solidify and dry.

Usage Instructions: Samples can be directly plated or pre-enriched according to ISO/TS 22964. Incubate at 41.5°C ± 1°C for 24 hours ± 2 hours. Typical colony appearances include green to blue for Cronobacter spp., colorless or other colors for other gram-negative bacteria, and inhibition for gram-positive bacteria.

Quality Control: Perform quality control using ATCC strains such as C. sakazakii and E. coli. Plates should not be used if contaminated or expired.

Warnings: Use only in laboratories by trained personnel. Deviations from procedures or storage conditions can affect results. Dispose of contaminated materials by autoclaving at 121°C for at least 20 minutes.
