Vitek Systems' Gram-Positive Identification test (GPI) card was evaluated for the ability to identify 12 coagulase-negative Staphylococcus species and subspecies. The bionumber generated from the GPI card was examined for its potential use in epidemiological studies. Results indicated that the GPI card had a high degree of correlation with the conventional methods of identification. The species identified with the greatest accuracy were Staphylococcus epidermidis (92%), S. haemolyticus (95%), S. capitis subsp. capitis (88%), and S. saprophyticus (100%). S. hominis (63%) was identified with the least accuracy. The bionumber was found to have limited epidemiological value because of the frequent occurrence of a few major bionumbers.
对Vitek系统的革兰氏阳性菌鉴定测试(GPI)卡识别12种凝固酶阴性葡萄球菌菌种和亚种的能力进行了评估。对GPI卡生成的生物编号在流行病学研究中的潜在用途进行了研究。结果表明,GPI卡与传统鉴定方法具有高度相关性。鉴定准确率最高的菌种为表皮葡萄球菌(92%)、溶血葡萄球菌(95%)、头状葡萄球菌头状亚种(88%)和腐生葡萄球菌(100%)。人葡萄球菌的鉴定准确率最低(63%)。由于少数主要生物编号频繁出现,发现生物编号的流行病学价值有限。
