Predominance of pHK01-like incompatibility group FII plasmids encoding CTX-M-14 among extended-spectrum beta-lactamase-producing Escherichia coli in Hong Kong, 1996-2008 [PDF]

, 2012
This study assessed the temporal changes in the molecular epidemiology of bacteremic Escherichia coli isolates producing CTX-M-14 in Hong Kong. Blood isolates from 1996 to 1998 (period 1, n = 50) and 2007 to 2008 (period 2, n = 117) were investigated by ...

Resistance to Broad-Spectrum Antibiotics in Aquatic Systems: Anthropogenic Activities Modulate the Dissemination of blaCTX-M-Like Genes [PDF]

, 2012
We compared the resistomes within polluted and unpolluted rivers, focusing on extended-spectrum beta-lactamase (ESBL) genes, in particular blaCTX-M. Twelve rivers from a Portuguese hydrographic basin were sampled.

Comparative Characterization of CTX-M-64 and CTX-M-14 Provides Insights into the Structure and Catalytic Activity of the CTX-M Class of Enzymes [PDF]

Antimicrobial Agents and Chemotherapy, 2016
ABSTRACT Clinical isolates producing hybrid CTX-M β-lactamases, presumably due to recombination between the bla CTX-M-15 and bla CTX-M-14 elements, have emerged in recent years.

CTX-M-123, a Novel Hybrid of the CTX-M-1 and CTX-M-9 Group β-Lactamases Recovered from Escherichia coli Isolates in China [PDF]

Antimicrobial Agents and Chemotherapy, 2013
ABSTRACT The chimeric bla CTX-M-123 gene was identified in two ceftazidime-resistant Escherichia coli isolates from animals in different Chinese provinces. Like other CTX-M-1/9 group hybrids (CTX-M-64 and CTX-M-132), the ends (amino acids 1 to 135 and 234 to 291) of CTX ...

Multiclonal outbreak of Klebsiella pneumoniae producing extended-spectrum beta-lactamase CTX-M-2 and novel variant CTX-M-59 in a neonatal intensive care unit in Brazil [PDF]

, 2008
An outbreak of cephalosporin-resistant Klebsiella pneumoniae occurred in a neonatal intensive care unit in São Paulo, Brazil. Of the 10 pulsotypes identified during the outbreak and follow-up periods, nine produced CTX-M-2 or its new variant CTX-M-59 and

Multiparametric determination of genes and their point mutations for identification of beta-lactamases [PDF]

, 2010
More than half of all currently used antibiotics belong to the beta-lactam group, but their clinical effectiveness is severely limited by antibiotic resistance of microorganisms that are the causative agents of infectious diseases. Several mechanisms for
