Emergence of Klebsiella pneumoniae isolates producing inducible DHA-1 beta-lactamase in a university hospital in Taiwan.
The study identifies the emergence of Klebsiella pneumoniae isolates producing inducible DHA-1 beta-lactamase, which confers resistance to ceftazidime, cefotaxime, and aztreonam.
Occurrence of newer beta-lactamases in Klebsiella pneumoniae isolates from 24 U.S. hospitals.
The study identified several beta-lactamases, including bla DHA-1, bla ACT-1, bla FOX-5, bla CMY-2, and bla KPC-2, in Klebsiella pneumoniae isolates from 24 U.S. hospitals. These enzymes confer resistance to various beta-lactam antibiotics.
Identification of a novel cephalosporinase (DHA-3) in Klebsiella pneumoniae isolated in Taiwan.
A novel cephalosporinase, DHA-3, was identified in a clinical isolate of Klebsiella pneumoniae. The gene was non-self-transferable but could be introduced into E. coli via electrotransformation, leading to resistance against several β-lactam antibiotics.
