Abstract

Direct tube coagulase testing for identification of Staphylococcus aureus from BACTEC culture broth showed a sensitivity, a specificity, and positive and negative predicative values of 34%, 100%, 100%, and 80.2% with 2 h of incubation and 65%, 98.7, 99.7%, and 88.6% with 4 h of incubation. Anaerobic blood culture contributed significantly to the detection of S. aureus.

摘要

采用直接试管凝固酶试验从BACTEC培养液中鉴定金黄色葡萄球菌,孵育2小时时,其敏感性、特异性、阳性预测值和阴性预测值分别为34%、100%、100%和80.2%;孵育4小时时,分别为65%、98.7%、99.7%和88.6%。厌氧血培养对金黄色葡萄球菌的检测有显著贡献。
