Proteus mirabilis and P. This article has been corrected.

The most common UTI pathogen is E. Moreover, since it is easy to differentiate mixed flora on CHROMagar Orientation, orientatioj susceptibility tests can be performed directly from primary isolates without the need of subcultures.

The use of CHROMagar Orientation as a primary isolation medium with presumptive identification for the routine screening of urine specimens Publication. Evaluation of use of a new chromogenic agar in detection of urinary tract pathogens Publication. The medium was found to facilitate easy visual detection of mixed bacterial isolates in culture. Find all citations in this journal default.

Performance of four chromogenic urine culture media after one or two days of incubation compared with reference media Publication. Add to my list. Save Time and Reduce Workload: This tool allows a same-day results in both fields, the identification and susceptibility, directly in the primary culture, contrary to the orientatioh traditional protocol which takes 48 hours.


These mixed growths were not obvious on the routine susceptibility testing medium Isosensitest. By contrast, 15 of 16 P. Gene Ontology GO Terms.

Screening prior to prostatic biopsy – a disk diffusion based method for detection of fluoroquinolone resistant Enterobacteriaceae in rectal swabs S. Pluri-microbial samples as well as monomicrobial- contaminated samples can be easily investigated by this method. The second application is the common Urine Tract Infections UTI for which physicians usually prescribe an empiric therapy.

When used in a replicator system, it easily detected mixed growths of organisms which may have otherwise led chromgar false antibiotic susceptibility results. Microbiology Culture Medium Chromogenic. This product was developed with the aim to speed up the time to results by combining the chromogenic differentiation of the species in the sample, and the antibiotic susceptibility test.

Addition of disk diffusion based screening on chromogenic Mueller-Hinton agar adds value to traditional cephalosporin based screening for multiresistant Gram-negative bacteria H.

Thus, any workload reduction related to this analysis will dramatically improve the efficiency of the laboratory.

Similarity in color resulted in failure to discriminate accurately between Klebsiella, Enterobacter, and Citrobacter species.


Shortening the period in which empirical therapy can be optimized results in better outcomes. However, these species could be readily differentiated from other members of the family Enterobacteriaceae. Comparative Study, research-article, Journal Article. CHROMagar Orientation can also be used to differentiate various microrganisms in other infected areas; e.
