abstract：:The diversity of OXA-48-like carbapenemases is continually expanding. In this study, we describe the dissemination and characteristics of a novel carbapenem-hydrolyzing class D β-lactamase (CHDL) named OXA-436. In total, six OXA-436-producing Enterobacteriaceae isolates, including Enterobacter asburiae (n = 3), Citrob...
