Plasmid pSfr64a and the symbiotic plasmid pSfr64b of Sinorhizobium fredii GR64 control each other's conjugative transfer through quorum-sensing elements
(Academic Press Inc Elsevier Science, 2019-11)
Rhizobia are nitrogen-fixing symbionts of plants. Their genomes frequently contain large plasmids, some of which are able to perform conjugative transfer. Plasmid pSfr64a from Sinorhizobium fredii GR64 is a conjugative ...
Spread of clonally related escherichia coli strains harboring an IncA/C1Plasmid encoding IMP-8 and its recruitment into an unrelated MCR-1-containing isolate
(American Society for Microbiology, 2018-06)
Ten IMP-8-producing Escherichia coli isolates were recovered from surveillance cultures of a neonatal intensive care unit; eight of the isolates were clonally related. A 168.2-kb blaIMP-8 plasmid was fully sequenced, and ...
Evaluation and characterization of plasmids carrying CTX-M genes in a non-clonal population of multidrug-resistant Enterobacteriaceae isolated from poultry in Brazil
(2016-08-01)
The increasing presence of ESBL-producing bacteria in food-producing animals might impact on public health. In this study, ESBL-producing enterobacteria were investigated in the microbiota of chickens produced in Brazil. ...
First Report of OXA-181-Producing Enterobacterales Isolates in Latin America
(American Society for Microbiology, 2023)
We characterized five carbapenemase-producing <i>Enterobacterales</i> (CPE) isolates from two health care institutions in Lima, Peru. The isolates were identified as Klebsiella pneumoniae (<i>n</i> = 3), Citrobacter ...
Insight into the structure, function and conjugative transfer of pLPU83a, an accessory plasmid of Rhizobium favelukesii LPU83
(Academic Press Inc Elsevier Science, 2019-05)
Plasmids are widely distributed in rhizobia, a group of bacteria able to establish symbiotic relationships with the roots of legume plants. Two types of conjugative transfer (CT) regulation of these elements have been ...
Antibiotic resistance and heavy metal tolerance plasmids: The antimicrobial bulletproof properties of escherichia fergusonii isolated from poultry
(2019-01-01)
We describe the mobilome of Escherichia fergusonii 40A isolated from poultry, consisting of four different plasmids, p46_40A (IncX1, 45,869 bp), p80_40A (non-typable, 79,635 bp), p150_40A (IncI1-ST1, 148,340 bp) and p280_40A ...
Characterization of escherichia colicarrying mcr-1-plasmids recovered from food animals from Argentina
(Frontiers Media S.A., 2019-03-06)
In this study, we found mcr-1.1 and mcr-1.5 genes carried by IncI2 plasmids in a subset of Escherichia coli isolates recovered from commercial broiler farms in Argentina. The comparative analysis of the sequences of these ...
