The GNI+ card has been developed by bioMerieux Vitek as an improvement over the GNI card for the identification of certain species of aerobic and facultative anaerobic bacteria. In this study, we tested 304 organisms from 30 different species on both the GNI and GNI+ cards. The GNI card correctly identified 285 (93.8%) of the isolates tested, and the GNI+ card correctly identified 287 (94.4%) of the isolates tested. The average time to reporting was 4.1 h for the GNI+ card compared to 5.7 h for the GNI card (P < 0.001). Overall, the GNI and GNI+ cards were comparable in identifying the organisms in this study while the GNI+ card gave substantially faster final test results.
