Transmission of IncN plasmids carrying blaCTX-M-1 between commensal Escherichia coli in pigs and farm workers.

چکیده
CTX-M-1-producing Escherichia coli were isolated from 56 pigs, three farm personnel, two manure samples, and two air samples from two Danish pig farms where an association between prophylactic ceftiofur use and the occurrence of cephalosporin resistance was previously demonstrated. Human, animal, and environmental strains displayed high genetic diversity but harbored indistinguishable or closely related IncN plasmids carrying bla(CTX-M-1), indicating that IncN plasmids mediating cephalosporin resistance were transmitted between pigs and farm workers across multiple E. coli lineages.

OBJECTIVES The aim of this study was to determine the occurrence of extended-spectrum β-lactamase (ESBL)-producing Escherichia coli at an equine clinic and a horseback riding centre, and to discuss the impact of antimicrobial treatment on resistance selection. METHODS Faeces from horses, environmental smears and flies were sampled at both the clinic and riding centre. Staff at the equine clin...
متن کاملIncI1/ST3 and IncN/ST1 plasmids drive the spread of blaTEM-52 and blaCTX-M-1/-32 in diverse Escherichia coli clones from different piggeries.
OBJECTIVES The spread of ESBL-producing Enterobacteriaceae among food animals/products has raised concerns about their possible transmission through the food chain. We aimed to characterize piggeries (pigs, piggery environments) as reservoirs of TEM-52- and CTX-M-encoding plasmids and clones. METHODS Forty-three samples from five Portuguese intensive production farms were studied (2006-07). T...

The objective of this study was to assess the impact of diverse plasmids bearing colistin resistance gene mcr-1 on host fitness. Forty-seven commensal E. coli isolates recovered from the pig farm where mcr-1 was first identified were screened for mcr-1. mcr-1-bearing plasmids were characterized by sequencing. The fitness impact of mcr-1-bearing plasmids was evaluated by in vitro competition ass...
