Clinical Microbiology

Addition of disk diffusion based screening on chromogenic Mueller-Hinton agar adds value to traditional cephalosporin based screening for multiresistant Gram-negative bacteria H. Pluri-microbial samples as well as monomicrobial- contaminated samples can be easily investigated by this method.

This tool allows a same-day results in both fields, the identification and susceptibility, directly in the primary culture, contrary vhromagar the concomitant traditional protocol which takes 48 hours. Evaluation of use of orienyation new chromogenic agar in detection of urinary tract pathogens Publication. Optimizacion de recursos en el diagnostico de infecciones urinarias en pediatra Publication.

CHROMagar™ Orientation Chromogenic Media Focus on Urinary tract pathogens

The medium was found to facilitate easy visual detection of mixed bacterial isolates in culture. In this case also as in the VAP, the same-day identification and susceptibility results can confirm the empirical therapy, or help in the decision to change it. Costs-effective and rapid presumptive identification of Gram negative bacilli in routine urine, pus and stool cultures: In the latter case, please orifntation on Javascript support in your web browser and reload this page.

Oriemtation Culture Medium Chromogenic. This colony color changed to blue after 2 to 3 h of incubation at room temperature. However, these species could be readily differentiated from other members of the family Enterobacteriaceae. For isolation and differentiation of urinary tract pathogens.

Shortening the period in which empirical therapy can be optimized results in better outcomes. Similarity in color resulted in failure to discriminate accurately between Klebsiella, Enterobacter, and Citrobacter species.

The second application is the common Urine Tract Infections UTI for which physicians usually prescribe an empiric therapy.

The use of CHROMagar Orientation as a primary isolation medium with presumptive identification for the routine screening of urine specimens Publication. See J Clin Microbiol Aug;35 8: Abstract A new chromogenic plate medium, CHROMagar Orientation, was evaluated for use in the differentiation and presumptive identification of gram-negative bacilli and Enterococcus species by a multipoint inoculation replicator technique.

Thus, any workload reduction related to this analysis will dramatically improve the efficiency of the laboratory. CitePeer Related Articles http: Screening prior to prostatic biopsy – a disk diffusion based method for detection of fluoroquinolone resistant Enterobacteriaceae in rectal swabs S.

CHROMagar Orientation can also be used to differentiate various microrganisms in other infected areas; e. Journal of Clinical Microbiology [01 Jul34 7: High Detection of Minor Populations: Comparative Study, research-article, Journal Article. Urianalysis is the most common clinical microbial test.

Performance of four chromogenic urine culture media after one or two days of incubation compared with reference media Publication. Or filter your current search. The most common UTI pathogen is E. Orientatipn contrast, 15 of 16 P. Europe PMC requires Chrkmagar to function effectively. Isolation of a Variety of Microrganisms: Proteus mirabilis and P. When used in a replicator system, it easily detected mixed growths of organisms which may have otherwise led to false antibiotic susceptibility results.

CHROMagar Orientation and CHROMagar MRSA

Six control American Type Culture Collection strains were also included with the testing to ensure quality control of the media. These mixed growths were not obvious on the routine susceptibility testing medium Isosensitest.

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.

Moreover, since it is easy to differentiate mixed flora on CHROMagar Orientation, antimicrobial susceptibility tests can be performed directly from primary isolates without the need of subcultures.


This study, carried with over 20 classical antimicrobial agents, concluded that the use of our medium with Etest can provide same day results. How does Europe PMC derive its citations network?
