[Comparative assessment of two test systems for identification of enterobacteria].

Ninety-seven enterobacterial isolates from patients were identified parallel by Enterotest and MMT E1, a new test system developed in Russia. Enterotest helped identify 97% of enterobacterial strains, MMT E1 86.6%. The results coincided in 83.5% of cases. Enterotest system often failed to demonstrate reaction to phenylalanine, this impeding Proteus identification. Some tests failed in MMT E1 as well. Elimination of these shortcomings will improve the reliability of the test systems and permit their wider use at practical clinical microbiology laboratories.
