Dissemination of CTX-M-Producing Escherichia coli in Freshwater Fishes From a French Watershed (Burgundy)

2019

International audience; The burden of extended-spectrum beta-lactamases producing Escherichia coli (ESBL-Ec), has increased over several decades. Freshwater ecosystems are suspected to play an important ecological and evolutionary role in driving the dissemination of antimicrobial resistance. The aim of our study was to decipher the occurrence of ESBL-Ec in a small watershed (Ouche river, Burgundy, France), targeting environmental matrices and fishes. Among cefotaxime resistant E. coli (ctxR Ec) isolates, we detected and characterized 36 ESBL-Ec from water, biofilm and fish guts. ctxR Ec and ESBL-Ec were found in samples from sites near the first small town, located downstream from the wate…

Mobilisation of plasmid-mediated blaVEB-1 gene cassette into distinct genomic islands of Proteus mirabilis after ceftazidime exposure

2021

ABSTRACT Objectives We sought to integrate a VEB-1-encoding gene cassette into the integron of the MDR region of genomic islands (GIs) harboured by Proteus mirabilis strains after antibiotic exposure. Methods An IncP1 plasmid from Achromobacter xylosoxidans carrying the cassette array dfrA14–blaVEB-1–aadB was introduced by conjugation into five strains of P. mirabilis: PmBRI, PmABB, PmSCO and Pm2CHAMA harbouring Salmonella GI 1 and PmESC harbouring Proteus GI 1. Circular intermediates of the cassettes were amplified by PCR. blaVEB-harbouring P. mirabilis were exposed to increasing concentrations of ceftazidime each day. Presence of blaVEB-1 in the GI was assessed by PCR. The complete MDR re…

Serotypes, Antibiotic Resistance, and Class 1 Integrons in Salmonella Isolates from Pediatric Cases of Enteritis in Tehran, Iran

2011

The present study was conducted to investigate serotype distribution, antimicrobial resistance patterns, carriage of class 1 integron, and clonality of Salmonella strains isolated from patients aged 0-12 years in Tehran, Iran, during 2007-2008. A total of 139 Salmonella isolates were studied. Salmonella serotypes Enteritidis, Infantis, and Typhimurium included 84.9% of isolates, Enteritidis accounting for 41.7%. The most prevalent resistances were to doxycycline (64.7%), nalidixic acid (61.2%), tetracycline (51.8%), and streptomycin (42.8%). Fifty-three (38.1%) isolates contained class 1 integron. Eight different gene cassettes were identified, aadA1 being the most frequently encountered. P…
