Efficiency of a multitest system (Enterotube) for rapid identification of Enterobacteriaceae.

Evaluation of the enterotube system for identification of members of the family Enterobacteriaceae.

The Enterotube system was evaluated, in parallel with conventional bacteriological procedures for the identification of members of the family Enterobacteriaceae, by using bacterial strains from a variety of clinical specimens and from stock cultures. Excellent agreement between the two test systems was obtained with the following reactions: hydrogen sulfide, indole, Simmons' citrate, glucose, a...

Commercial identification systems often fail to identify Providencia stuartii.

We tested 145 clinical isolates in an attempt to evaluate some of the most widely used commercial identification systems in Europe in terms of their ability to identify Providencia strains. Two manual miniaturized systems (API 20E and Enterotube II) and three mechanized-automated systems (Cobas-Bact, Sceptor System, and Titertek-Enterobac-Rapid Automated System) were evaluated. Providencia alca...

Identification of the Enterobacteriaceae: a comparison of the Enterotube II with the API 20E.

Two commercial methods for the identification of the Enterobacteriaceae, API 20E and Enterotube II, were compared using the results obtained with 235 cultures of fresh clinical isolates. Enterotube II was an improvement on the original Enterotube, but the availability of two differing indices, one using the Voges-Proskauer (VP) test result and one without, is criticised.

A comparison of two commerical methods for the identification of the Enterobacteriaceae--API 20E and the Enterotube--with conventional methods.

The API 20E, the Enterotube, and routine methods of Cowan and Steel were used in parallel to identify 245 members of the Enterobacteriaceae. The API 20E and conventional methods gave the same identification in all but 2 (0-8%) of the 245 organisms tested. The Enterotube correctly identified 85% of these organisms on the first testing. On re-testing those organisms incorrectly identified the Ent...
