plasmid-mediated AmpC beta-lactamase
Overview
Modified CLSI extended-spectrum beta-lactamase (ESBL) confirmatory test for phenotypic detection of ESBLs among Enterobacteriaceae producing various beta-lactamases.
The study evaluated a modified CLSI ESBL confirmatory test for the phenotypic detection of extended-spectrum beta-lactamases (ESBLs) among Enterobacteriaceae producing various beta-lactamases, including KPC, VIM, NDM, and OXA-48. The modified test significantly improved the sensitivity and specificity of ESBL detection compared to the standard CLSI test.
Plasmid-mediated AmpC: prevalence in community-acquired isolates in Amsterdam, the Netherlands, and risk factors for carriage.
The study identified 7 pAmpC-positive E. coli isolates, including 6 blaCMY-2-like and 1 blaDHA genes, highlighting the presence of plasmid-mediated AmpC in community-acquired isolates.
Decline in AmpC beta-lactamase-producing Escherichia coli in a Dutch teaching hospital (2013-2016).
The study reports a decline in rectal carriage of cAmpC hyperproducing E. coli in a Dutch hospital, with bla CMY-2-like and bla DHA-like genes being the primary plasmid-encoded AmpC beta-lactamases identified.
Wildlife as Sentinels of Antimicrobial Resistance in Germany?
The study identified various AMR genes, including bla CTX-M-1, bla CTX-M-15, bla CTX-M-14-like, bla CMY-2-like, and bla TEM-1, in Escherichia coli isolates from wild boars, roe deer, and wild ducks and geese in Germany. These genes conferred resistance to beta-lactam antibiotics such as cefotaxime, ceftazidime, and ampicillin.
Environmental factors associated with the prevalence of ESBL/AmpC-producing Escherichia coli in wild boar (Sus scrofa).
The study identified several ESBL/AmpC genes, including bla CTX-M-1, bla CTX-M-15, bla CTX-M-14-like, bla CTX-M-65, and bla CMY-2-like, in ESBL/AmpC-producing E. coli isolates from wild boar. These genes were associated with environmental factors such as cattle density and precipitation.
Molecular characterization of uropathogenic Escherichia coli (UPEC) strains isolated from companion dogs and cats in Korea.
The study identified several extended-spectrum beta-lactamase (ESBL) genes, including blaTEM-1, blaCTX-M-15, blaCTX-M-55, blaCTX-M-14, blaCTX-M-27, blaCMY-2, blaCMY-2-like, blaCMY-42, blaCMY-102, and blaNDM-5, in UPEC strains from companion dogs and cats in Korea. These genes conferred resistance to various beta-lactam antibiotics such as ampicillin, cefotaxime, and cefoxitin.
