A total of 136 isolates of Salmonella enterica serovar Typhimurium DT104 from Denmark (n = 93), Germany (n = 10), Italy (n = 4), Spain (n = 5), and the United Kingdom (n = 9) were characterized by antimicrobial resistance analysis, plasmid profiling, pulsed-field gel electrophoresis (PFGE) with the restriction enzymes XbaI and BlnI, and analysis for the presence of integrons and antibiotic resi...

Antibiotic-sensitive Salmonella isolates belonging to seven common serotypes and originating from 29 different countries from all continents were investigated for their plasmid DNA content (337 isolates) and their outer membrane protein profiles (216 isolates). Of the S. typhimurium, S. enteritidis, S. dublin, and S. choleraesuis isolates, 90% or more carried a serotype-specific plasmid. The mo...

Rhodococcus equi is an important bacterial pathogen in foals up to 6 months old, widespread in horse farms all over the world. It was found that only virulent R. equi strains expressing 15-17 kDa virulence-associated protein (VapA) and having large virulence plasmid of 85-90 kb containing vapA gene are pathogenic for horses. To date, 12 plasmid types have been reported in VapA positive strains ...

In 1988, a new plasmid profile was observed for Vibrio salmonicida isolated from cod (Gadus morhua) and Atlantic salmon (Salmo salar) in fish farms in northern Norway. This new plasmid profile, which consisted of plasmids of 61, 21, 3.4, and 2.8 megadaltons, is 1 of 11 plasmid profiles which have so far been observed for V. salmonicida. Plasmid profiling and plasmid DNA hybridization were used ...

plasmids play an important role in the virulence and antibiotic resistance of salmonella. salmonella carry plasmids having different size and number. plasmid profile analysis of single isolates of salmonella typhimurium and salmonella enteritidis revealed the presence of 4- plasmid profiles. salmonella serovars produce several type iii secretions including sop-e and sop –b. soap e is detected b...

Abstract The emergence and dissemination of colistin resistance in Enterobacteriaceae mediated by plasmid-borne mcr genes recent years now pose a threat to public health. In this study, we isolated characterized colistin-resistant and/or -positive E. coli from pig farms Central China. Between 2018 2019, 594 samples were collected recovered 445 isolates. Among them, 33 with phenotypes 37 that po...

The mcr-1 gene mediating mobile colistin resistance in Escherichia coli was first reported China 2016 followed by reports among different species worldwide, especially E. and Klebsiella . However, data on its transmission Salmonella are still lacking. This study analyzed the antimicrobial (AMR) profiles presence 755 foodborne from 26 provinces of mainland, 2016. Genomic features two mcr-1- carr...
