- -MHT positive = KPC + OXA48 - Boronic acid positive = KPC
- -MHT + Boronic acid positive = KPC -MHT positive + boronic acid negative = OXA 48
- Note: MHT applied only for Enterobacterceae. -EDTA positive = Metallo-β-lactamase.aThese isolates just positive by BA and not MHT.bOther Gram-negative bacilli include: Citrobacter species (3), Serratia species (1), Proteus spp. (2), Stenotrophomonas maltophilia (3), Vibrio vurneficus (1) and Morganella morganii (1).
