The Autobac IDX system was evaluated for its ability to accurately identify 290 gram-negative bacilli from 18 different genera. Excluding isolates with a low identification probability, the overall sensitivity of the system was found to be 95.8%. Late lactose-fermenting Escherichia coli, Citrobacter freundii, and Proteus mirabilis accounted for over 90% of the misidentifications. The Autobac IDX system offers a rapid and reliable method for the identification of gram-negative bacilli. An increased emphasis has been placed on the rapid identification and susceptibility testing of microorganisms. To this end, the Autobac system (General Diagnostics, Warner-Lambert Co., Morris Plains, N.J.) was introduced for rapid susceptibility testing of bacteria (6). Subsequently, the Autobac system was adapted for determination of minimum inhibitory concentrations (4), urine screening (3), and more recently for testing salt tolerance of streptococci (2). Additionally, the Autobac system has recently been updated and modified to include bacterial identification capabilities. Along with rapid identification of Enterobacteriaceae, the system has also been reported to rapidly identify nonfermentative gram-negative bacilli. Early reports delineating the data base indicated 88.4% (7) and 95.3% (1) agreement with conventional biochemical identification. Two recent reports have substantiated the accuracy of the Autobac identification system (N. M.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
