[Rapid identification of Enterobacteriaceae with the Micro-ID system (author's transl)].

Micro-ID, a new kit system for rapid identification of Enterobacteriaceae, was compared with a conventional media-system, the extended Enterotube system (completed with arabinose, rhamnose and the Voges-Proskauer reaction), and partially with the API-20E system. When the computer generated Identification Manual for Micro-ID was consulted the system showed complete agreement at the genus level, but differed in 5% at the species level. Problems arose from misidentifications by nonfermenting organisms. 15 turbid blood cultures with gramnegative rods were tested additionally. In 11 cases the Micro-ID provided correct identification of the species and in further 3 cases of the genus. In summary Micro-ID is easy to handle and an accurate, convenient kit for the short-term identification of Enterobacteriaceae.
