Abstract
CTX-M-14- and -2-like extended-spectrum beta-lactamases were detected in 5 and 1 Proteus mirabilis isolates, respectively, among 92 non-duplicate strains tested from December 2002 to September 2003. This is the first report of the CTX-M-14 enzyme in P. mirabilis to the best of our knowledge and suggests that the CTX-M-type enzyme is gradually spreading to this species. bla(TEM), bla(SHV-1), and/or bla(OXA-10) alleles were also detected in 35 ampicillin-resistant isolates tested.
