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. See J Clin Microbiol Aug;35 8: For isolation and differentiation of urinary tract pathogens. 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.

However, these species could be readily differentiated from other members of the family Enterobacteriaceae. Addition of disk diffusion based screening on chromogenic Mueller-Hinton agar adds value to traditional cephalosporin based screening for multiresistant Gram-negative bacteria H.

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. This tool allows a same-day results in both fields, the identification and susceptibility, directly in the primary culture, contrary to krientation concomitant traditional protocol which takes 48 hours.


When used in a replicator system, it easily detected mixed growths of organisms which may have otherwise led to false antibiotic susceptibility results. It allows chromogenic identification and antibiotic susceptibility in the same plate. Or filter your current search.

Pluri-microbial samples orienration 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. How does Europe PMC derive its citations network?

This article has been corrected. 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. The medium was found to facilitate easy visual detection of mixed bacterial isolates in culture.
