Risk factors associated with the community-acquired colonization of extended-spectrum beta-lactamase
(ESBL) positive Escherichia Coli.
Molecular and phenotypic characterization of Escherichia coli and Klebsiella pneumoniae producing extended-spectrum beta-lactamases
with focus on CTX-M in a low-endemic area in Sweden.
are most often produced by Escherichia coli and Klebsiella spp., which are members of Enterobacteriaceae family [7,8].
in the 21st century: characterization, epidemiology, and detection of this important resistance threat.
The newly discovered enzymes became known as extended-spectrum beta-lactamases
, or ES[beta]Ls.
They are distinct from extended-spectrum beta-lactamases
(ESBLs) by their ability to hydrolyse cephamycins and they are not affected by b-lactamase inhibitors.2 In the Ambler structural classification of b-lactamases, AmpC enzymes belong to class C, while in the functional classification scheme of Bush these are assigned to group 3.3

Rapid dissemination and diversity of CTX-M extended-spectrum beta-lactamase
genes in commensal Escherichia coli isolates from healthy children from low-resource settings in Latin America.
Escherichia coli emerges as an agent in 70-95% of community-acquired urinary tract infections andin 50% of hospital-acquired cases.1 The most important and common cause of resistance to beta- lactam antibiotics preferred to treat these infections is the production of beta-lactamase and especially extended-spectrum beta-lactamase
