Uechi K, et al. - Authors here described a modified carbapenem inactivation method (CIM), called the CIMTris, in which carbapenemase was extracted from bacteria with 0.5 M Tris-HCl (pH 7.6) buffer. In addition, they examined the ability of the CIMTris to detect carbapenemase production in Acinetobacter and Pseudomonas species. Findings suggested the utility of the CIMTris for detecting carbapenemase production in Acinetobacter and Pseudomonas species.
