Abstract
Enteric-Tek is a new system designed for the identification of Enterobacteriaceae [clinical (human) and stock isolates] and consists of a round, multicompartmented plastic plate with 11 peripheral wells and 1 center well incorporating 14 biochemical reactions. Only 1 reagent (Kovacs reagent) is required to complete the biochemical test results for generation of a 5-digit number for computer code identification. The identification accuracy of the Enteric-Tek system was compared with those obtained by conventional methods and API 20E. The Enteric-Tek system was found to be not only a convenient and simple method for rapid identification of Enterobacteriaceae, but also to be highly reliable, giving excellent identification performance as compared to API 20E and conventional methods.
