The ability of the expanded API-20E and the Oxi-Ferm System to identify 176 isolates of nonfermenting or oxidase-positive, gram-negative rods from 17 species or groups was studied. The expanded API-20E, without referral to a computer reference center, was able to identify 61.4% of the isolates to the species level. If reference to the computer center was utilized, an additional 25% could be identified. Of the isolates examined, 13.6% were misidentified, partially identified, or assigned no identification. Those assigned to the incorrect genus constituted 0.5% of the isolates tested; those assigned to the correct genus, but the wrong species, constituted 0.5%; 4.5% were placed in the correct genus with no species given; and 7.9% were assigned no identification. The Oxi-Ferm System was able to assign 75% of the isolates to the correct species without further testing, and an additional 19.3% required additional testing for correct identification. Those assigned to the incorrect genus represented 3.4% of the isolates tested; 1.1% were assinged to the correct genus, but the wrong species; and 1.1% were assigned to the correct genus, with no species indicated.
对扩展API - 20E和Oxi - Ferm系统鉴定来自17个物种或类群的176株非发酵或氧化酶阳性革兰氏阴性杆菌的能力进行了研究。扩展API - 20E在不参考计算机参考中心的情况下，能够将61.4%的菌株鉴定到种水平。如果利用计算机中心，则可再鉴定出25%。在所检查的菌株中，13.6%被错误鉴定、部分鉴定或未给出鉴定结果。被归为错误属的占所测试菌株的0.5%；被归为正确属但错误种的占0.5%；4.5%被置于正确属但未给出种名；7.9%未给出鉴定结果。Oxi - Ferm系统无需进一步测试就能将75%的菌株鉴定到正确种，另外19.3%需要进一步测试才能正确鉴定。被归为错误属的占所测试菌株的3.4%；1.1%被归为正确属但错误种；1.1%被归为正确属但未指明种名。
