Abstract

The manual broth micro-dilution (mBMD) is the recommended reference method for colistin minimum inhibitory concentration determination; however, it is not as readily available in South Africa as the Vitek®2. This retrospective study compared the performance of Vitek®2 against mBMD in determining the colistin minimum inhibitory concentration of 337 extensively drug-resistant Acinetobacter baumannii complex isolates. Vitek®2 yielded a categorical agreement of 89%, an essential agreement of 56%, a major error rate of 8% and a very major error rate of 55%. The Vitek®2 is not an alternative to mBMD for colistin susceptibility testing.

Vitek®2与手动肉汤微稀释在南非鲍氏不动杆菌分离株粘菌素敏感性测试中的性能对比回顾性分析
手动肉汤微量稀释法(mBMD)是测定粘菌素最小抑制浓度的推荐参考方法;然而,它在南非并不像Vitek®2那样容易买到。这项回顾性研究比较了Vitek®2对mBMD在确定337个广泛耐药的鲍曼不动杆菌复合物分离株的粘菌素最低抑制浓度方面的性能。Vitek®2得出89%的绝对一致性、56%的基本一致性、8%的主要错误率和55%的非常主要错误率。Vitek®2不是用于粘菌素敏感性测试的mBMD的替代品。

期刊介绍: The African Journal of Laboratory Medicine, the official journal of ASLM, focuses on the role of the laboratory and its professionals in the clinical and public healthcare sectors,and is specifically based on an African frame of reference. Emphasis is on all aspects that promote and contribute to the laboratory medicine practices of Africa. This includes, amongst others: laboratories, biomedical scientists and clinicians, medical community, public health officials and policy makers, laboratory systems and policies (translation of laboratory knowledge, practices and technologies in clinical care), interfaces of laboratory with medical science, laboratory-based epidemiology, laboratory investigations, evidence-based effectiveness in real world (actual) settings.
