“…As such, plasmids from this incompatibility group constitute a threat to public health and animal welfare. Of significance, Salmonella spp., E. coli , Klebsiella pneumoniae , and Enterobacter cloacae have all been identified as carriers of IncHI2 plasmids ( Wong et al, 2016 ; Matamoros et al, 2017 ; Zhao et al, 2018 ; Chaudhry et al, 2020 ). Gene operons encoding metal resistances, such as tellurium ( terZABCDE / Y3Y2XY1W ), mercury ( merRTPCADE ), copper ( pcoABCDRSE ), and silver ( silESRCBAP ) are also common-place in this plasmid family ( Fang et al, 2016 ).…”
