Extraintestinal pathogenic Escherichia coli sequence type 131 H30-R and H30-Rx subclones in retail chicken meat, Italy

2016

Extraintestinal pathogenic Escherichia coli sequence type 131 (ST131), typically fluoroquinolone-resistant (FQ-R) and/or extended-spectrum β-lactamase (ESBL)-producing, has emerged globally. Among clinical isolates, ST131, primarily its H30-R and H30-Rx subclones, accounts for most antimicrobial-resistant E. coli and is the dominant E. coli strain worldwide. We assessed its prevalence and characteristics among raw chicken meat samples on sale in Palermo, Italy. A collection of 237 fluoroquinolone resistant and ESBL/AmpC producing E. coli isolates, which had been isolated from processed retail chicken meat in the period May 2013-April 2015, was analyzed. Established polymerase chain reaction…

Outbreak of colonizations by extended-spectrum β-lactamase-producing Escherichia coli sequence type 131 in a neonatal intensive care unit, Italy

2013

Abstract Background Extended spectrum β-lactamases (ESBLs) often associated with resistance to aminoglycosides and fluoroquinolones have recently emerged in community-associated Escherichia coli. The worldwide clonal dissemination of E. coli sequence type (ST)131 is playing a prominent role. We describe an outbreak of colonizations by ESBL-producing E. coli (ESBL-E. coli) in the neonatal intensive care unit (NICU) of the University Hospital, Palermo, Italy. Methods An epidemiological investigation was conducted with the support of molecular typing. All children admitted to the NICU and colonized by ESBL-E. coli between January and June 2012, were included in the study. Cases were defined as…

Comparison of multidrug-resistant extraintestinal pathogenic Escherichia coli from human, foods and animals to investigate the possible chains of tra…

Background Globally, antimicrobial drug resistant Escherichia coli is the most common etiological agent of invasive disease in humans. In Europe, increasing proportions of infections due to third generation cephalosporins (3GCs) and/or fluoroquinolone resistant extraintestinal pathogenic E. coli (ExPEC) strains are reported. It has been shown that multidrug resistant (MDR) E. coli can be transmitted from animals to humans and based on existing evidence, poultry is the food animal source most closely linked to human E. coli. However, lack of reliable data makes it difficult to assess the attributable risk of different food sources and their impact on human health. Objectives In the present s…
