Predominance of CTX-M-type extended-spectrum beta-lactamase genes among enterobacterial isolates from outpatients in Brazil
(ELSEVIER SCIENCE INC, 2009)
Two hundred fifty-seven nalidixic acid-resistant enterobacterial isolates were collected in a Brazilian community from January 2000 to May 2005 to determine the prevalence of plasmid-encoded extended-spectrum beta-lactamases. ...
IncIl/ST113 and IncIl/ST114 conjugative plasmids carrying bla(CTX-M-8) in Escherichia coli isolated from poultry in Brazil
(Elsevier B.V., 2014-12-01)
Extended-spectrum beta-lactamase-producing Escherichia coli isolated from poultry in Brazil showed bla(CTX-M-8) gene. IS10 was found upstream of bla(CTX-M-8), harbored on plasmids Inch, ST113/ST114 subtypes. Genomic ...
Novel chromosome-encoded CTX-M-78 β-lactamase from a Kluyvera georgiana clinical isolate as a putative origin of CTX-M-25 subgroup
(American Society for Microbiology, 2010-07)
While TEM- and SHV-derived extended-spectrum β-lactamases (ESBLs) arose by point mutations in genes encoding broad-spectrum variants that were extensively disseminated into mobile elements, CTX-M β-lactamases are derived ...
ISCR1 associated with blaCTX-M-1 y blaCTX-M-2 genes in IncN and IncFIIA plasmids isolated from Klebsiella pneumoniae of nosocomial origin in Mérida, Venezuela
(Inst Nacional Salud, 2013-08)
Introduction: Insertion sequences such as ISCR1 promote capture, transposition and expression of blaCTX-M genes. Thus, gene dissemination in bacterial populations occurs rapidly. Objective: To determine the presence ...
Caracterización molecular y detección de genes blaCTX-M grupos 1 y 9 en Klebsiella pneumoniae resistentes a ceftazidima, en un hospital de San José de Cúcuta, Colombia
(Revista Chilena de InfectologiaSantiago de Chile , Chile, 2019-06)
Background: The expression of CTX-M β-lactamases belonging to groups 1 and 9 in Klebsiella pneumoniae
produces high levels of resistance to ceftazidime, and they have a wide distribution worldwide. Aim: To identify
and ...

Redefining the origin and evolution of chromosomally encoded blaCTX-M/KLU in the context of a revised taxonomy of genus Kluyvera
(American Society for Microbiology, 2021-06-17)
Changes in Kluyvera taxonomy may clarify each species contribution for recruitment and dissemination of their relevant b-lactamases. The CTX-M-2 subgroup is linked to Kluyvera ascorbata, KLUC to Kluyvera cryocrescens, and ...
