To compare the identification accuracies of VITEK 2 (bioMérieux), MicroScan (Siemens Healthcare), and Phoenix (Becton Dickinson), microbial identification was performed on 160 clinical isolates and 50 reference strains on each of these 3 systems, using the appropriate identification kit provided by each system. Of the 142 clinical isolates that were identified at the species level, VITEK 2, MicroScan, and Phoenix correctly identified 93.7%, 82.4%, and 93.0%, and incorrectly identified 2.1%, 7.0%, and 0%, respectively. In the reference strain tests, VITEK 2, MicroScan, and Phoenix correctly identified 55.3%, 54.4%, and 78.0% of the reference strains at the species level and incorrectly identified 10.6%, 13.0%, and 6.0% of the reference strains, respectively. In conclusion, the identification rate of VITEK 2, Phoenix, and MicroScan was high or acceptable on clinical isolates. Phoenix showed a significantly higher performance than VITEK 2 or MicroScan in identifying the reference strains.
为了比较 VITEK 2（生物梅里埃）、MicroScan（西门子医疗）和 Phoenix（BD）这三种系统的鉴定准确性，我们在这三种系统上分别对 160 株临床分离株和 50 株参考菌株进行了微生物鉴定，使用了每种系统提供的适当的鉴定试剂盒。在被鉴定到种水平的 142 株临床分离株中，VITEK 2、MicroScan 和 Phoenix 的正确鉴定率分别为 93.7%、82.4%和 93.0%，错误鉴定率分别为 2.1%、7.0%和 0%。在参考菌株测试中，VITEK 2、MicroScan 和 Phoenix 对种水平的 55.3%、54.4%和 78.0%的参考菌株的正确鉴定率，错误鉴定率分别为 10.6%、13.0%和 6.0%。总之，VITEK 2、Phoenix 和 MicroScan 在临床分离株上的鉴定率较高或可接受。Phoenix 在鉴定参考菌株方面的性能明显优于 VITEK 2 或 MicroScan。
