CHROMagar™ Orientation

Productcode: RT413-25
Supplier: CHROMagar
Package size: 25000 ml

Product information

For isolation and differentiation
of urinary tract pathogens.

CHROMagarTM Orientation has several advantages over traditional media:
- allows in most cases full differentiation of the pathogens
- allows for reliable detection, enumeration and presumptive identification of urinary
tract pathogens
- easier recognition of mixed growth
- provides higher detection rates

Typical Appearance of microrganisms

E.coli → dark pink to reddish
Enterococcus → turquoise blue
Klebsiella, Enterobacter, Citrobacter → metallic blue
Proteus → brown halo
Pseudomonas → cream, translucent
S.aureus → golden, opaque, small
S.saprophyticus → pink, opaque, small

Evaluation of Chromogenic Media for the Work-up of Urine Specimens: Comparison of chromIDTM CPS®, BBL™ CHROMagar™ and Colorex Orientation™ to Conventional Urine Culture Method

Chromogenic media offer the potential for more rapid identification of urinary pathogens while improving workflow by rapid elimination of contaminated culture. The purpose of this study was to compare the performance of three different chromogenic media (CHROM); chromID™ CPS® (CPS), BBL™ CHROMagar™ (BBL) and Colorex Orientation™ (CLX) to conventional urine culture (CUC) methods. Conclusions: (1) CLX outperformed both CPS and BBL in terms of overall agreement with the CUC and had no VMD. (2) The performance of all three CHROM was enhanced by including a CNA plate. (3) Despite the higher cost of CHROM/CNA combination compared to BAP/MAC, the CHROM/CNA combination will reduce overall laboratory costs by improving turn-around time to reporting, decreasing utilization of both manual and automated testing, and reducing technologist workload.

Cost-Effective and Rapid Presumptive Identification of Gram-Negative Bacilli in Routine Urine, Pus, and Stool Cultures: Evaluation of the Use of CHROMagar™ Orientation Medium in Conjunction with Simple Biochemical Tests

The algorithm for a new identification system was designed on the basis of colony color and morphology on CHROMagar™ Orientation medium in conjunction with simple biochemical tests. The accuracy and cost-effectiveness of this new system were prospectively evaluated with a total of 472 gram-negative bacillus isolates which were detected on CHROMagar™ Orientation medium. For 466 of the isolates (98.7%), no discrepancies in the results were obtained on the basis of the identification algorithm. CHROMagar™ Orientation permitted reliable detection and presumptive identification. In addition, this rapid identification system not only significantly reduced costs but it also improved the daily work flow within the clinical microbiology laboratory.
