Beta-lactams are widely used to treat bacterial infections in humans. In most countries, they
are the largest group of antibiotics used by hospitals to treat infections caused by Gram …

The spread of Gram-negative bacteria with plasmid-borne extended-spectrum beta-
lactamases (ESBLs) has become a worldwide problem. Their prevalence is increasing, both …

Water environments play an important role in the dissemination of antibiotic-resistant
bacteria among humans, animals and agricultural sources. In order to assess the spread of …

Background Extended-spectrum β-lactamase-producing Escherichia coli has become
ubiquitous and has been reported in diverse ecosystems. We evaluated the potential impact …

The assessment of the hospital environment as a reservoir of ESBL-producing
Enterobacteriaceae in Tunisian hospitals is scarcely analyzed, except for Escherichia coli …

Extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae are a major
public health concern. We previously demonstrated the presence of ESBL-producing …

One of the currently most relevant resistance mechanisms in Enterobacteriaceae is the
production of enzymes that lead to modern expanded-spectrum cephalosporin and even …

Objectives: This study aimed to determine the presence of extended-spectrum β-lactamase
(ESBL)-producing Enterobacteriaceae in different environments. Methods: Clinical samples …

For many years, extended-spectrum-beta-lactamase (ESBL) producing bacteria were a
problem mainly located in medical facilities. Within the last decade however, ESBL …

Wastewater is considered a hotspot niche of multi-drug and pathogenic bacteria such as
Enterobacteriaceae-producing extended-spectrum beta-lactamases (ESBL-E). Thus, the aim …
