Abstract

The 10 biochemical test strips included in the PathoTec Rapid I-D System were evaluated for accuracy as compared to standard tests and for efficacy in identification of 193 gram-negative bacilli. The test agreement was 100% for oxidase and phenylalanine deaminase, 99% for indole, nitrate, and Voges-Proskauer, 98% for malonate, 97% for lysine decarboxylase, 90% for urease, 84% for H(2)S, and 75% for esculin hydrolysis. Most of the commonly isolated Enterobacteriaceae were identified correctly within 4 h. Errors in identification of Proteus morganii and P. rettgeri occurred because of positive H(2)S tests on the PathoTec strips with these organisms.

摘要

将PathoTec快速鉴定系统中包含的10种生化测试条与标准测试相比,评估其准确性,并评估其对193株革兰氏阴性杆菌的鉴定效力。氧化酶和苯丙氨酸脱氨酶的测试一致性为100%,吲哚、硝酸盐和Voges-Proskauer的测试一致性为99%,丙二酸盐的测试一致性为98%,赖氨酸脱羧酶的测试一致性为97%,脲酶的测试一致性为90%,H(2)S的测试一致性为84%,七叶苷水解的测试一致性为75%。大多数常见分离的肠杆菌科细菌在4小时内被正确鉴定。由于这些生物体在PathoTec测试条上的H(2)S测试呈阳性,导致摩根变形杆菌和雷氏变形杆菌的鉴定出现错误。
