Urban wastewater treatment plants (UWTPs) are among the main sources of antibiotics'
release into the environment. The occurrence of antibiotics may promote the selection of …

The primary habitat of Escherichia coli is the vertebrate gut, where it is the predominant
aerobic organism, living in symbiosis with its host. Despite the occurrence of recombination …

The spread of antibiotic-resistant bacteria is a growing problem and a public health issue. In
recent decades, various genetic mechanisms involved in the spread of resistance genes …

Given the significant spatial and temporal heterogeneity in antimicrobial resistance
distribution and the factors that affect its evolution, dissemination, and persistence, it is …

Objectives In view of the intercontinental emergence of Escherichia coli clone O25: H4-
ST131 producing CTX-M-15 extended-spectrum β-lactamase (ESBL) in human clinical …

Integrons are versatile gene acquisition systems that allow efficient capturing of exogenous
genes and ensure their expression. Various classes of integrons possessing a wide variety …

This study examined in detail the population structure of Escherichia coli from healthy adults
with respect to the prevalence of antibiotic resistance and specific resistance determinants …

To identify forces shaping the Escherichia coli intraspecies ecological structure, we have
characterized in terms of phylogenetic group (A, B1, D and B2) belonging …

Objectives: To determine the level of antimicrobial resistance and the occurrence of class 1,
2 and 3 integrons in faecal Escherichia coli from several animal populations variously …

Objectives Integrons are bacterial genetic elements that can capture and express genes
contained in mobile cassettes. Integrons have been described worldwide in Gram-negative …
