ColE1-like plasmid pIP843 of Klebsiella pneumoniae encoding extended-spectrum beta-lactamase CTX-M-17.
The resistance of Klebsiella pneumoniae BM4493, isolated in Ho Chi Minh City, Vietnam, to cefotaxime and aztreonam was due to production of a novel beta-lactamase, CTX-M-17. The bla(CTX-M-17) gene was borne by 7,086-bp plasmid pIP843, which was entirely sequenced and which was found to belong to the ColE1 family. The 876-bp bla(CTX-M-17) gene differed from bla(CTX-M-14) by 2 nucleotides, which ...
متن کاملDissemination of Clonally Related Escherichia coli Strains Expressing Extended-Spectrum β-Lactamase CTX-M-15
We analyzed 43 CTX-M-15-producing Escherichia coli isolates and 6 plasmids encoding the blaCTX-M-15 gene from Canada, India, Kuwait, France, Switzerland, Portugal, and Spain. Most isolates belonged to phylogroups B2 (50%) and D (25%). An EC-B2 strain of clonal complex sequence type (ST) 131 was detected in all countries; other B2 isolates corresponded to ST28, ST405, ST354, and ST695 from speci...
متن کاملLiver abscess caused by CTX-M-55-type extended-spectrum β-lactamase (ESBL)-producing Salmonella enteritidis.
Liver abscesses secondary to Salmonella species are rarely described in the general population. We herein describe a case of a liver abscess caused by CTX-M-55-type extended-spectrum β-lactamase (ESBL)-producing Salmonella enteritidis, which has not been reported in the literature. A 54-year-old male was admitted due to a high fever and was clinically diagnosed with a liver abscess. Culture of ...
متن کاملComplete Genome Sequences of Two Phage-Like Plasmids Carrying the CTX-M-15 Extended-Spectrum β-Lactamase Gene
Two similar phage-like plasmids carrying CTX-M-15 resistance cassettes were identified from two environmental Escherichia coli isolates. They demonstrate strong nucleotide sequence identity to the phage-like plasmid pECOH89 and Salmonella bacteriophage SSU5.

(20 min) with the inactivator, using the same reporter substrate. Inactivation by clavulanic acid was observed only after preincubation competitive assays (indirect IC501⁄456 mM). On the other hand, 3-phenyl boronic acid showed enzymatic inactivation in both competitive and pre-incubation assays at high concentrations (direct IC501⁄4390 mM and indirect IC501⁄4151 mM). INQ-1 seems to be a cephal...
