“…The range of bacterial species they have encountered is limited to E. coli, K. pneumoniae, E. cloacae , and the S. enterica serotypes Concord, Enteritidis, Heidelberg and Kiambu. Nevertheless, IncI1 plasmids (19–340 Kb) occur in very diverse settings: bla SHV-2 - and bla SHV-12 -encoding isolates from human infections (Bulgaria, France, Italy, Spain, Taiwan; Tato et al, 2007; Marcadé et al, 2009; Accogli et al, 2013; de Toro et al, 2013; Markovska et al, 2014; Chen C. M. et al, 2015) and colonization (Ethiopia) (Fabre et al, 2009); bla SHV-2 -, bla SHV-2 a –, and bla SHV-12 -encoding isolates from poultry (Canada, Italy, Portugal; Bortolaia et al, 2010, 2011; Accogli et al, 2013; Pouget et al, 2013; Jones-Dias et al, 2015), bla SHV-2 - and bla SHV-2 a -encoding isolates from pigs (Canada) (Pouget et al, 2013); bla SHV-12 -encoding isolates from aquatic birds (Poland) (Literak et al, 2010); and bla SHV-12 -encoding isolates from farming soil (Portugal) (Jones-Dias et al, 2016). Remarkably, bla SHV-12 on IncI1 plasmids belonging to pST26 have been identified among E. coli isolates of human and animal origin (Accogli et al, 2013; Jones-Dias et al, 2015), indicating the potential transmission of these bla SHV-12 -encoding vehicles from human to animals and/or vice versa.…”
