Characterization of a fosA3 Carrying IncC-IncN Plasmid From a Multidrug-Resistant ST17 Salmonella Indiana Isolate.

ABSTRACT: The aim of this study was to investigate the characteristics of a fosA3 carrying IncC-IncN plasmid from a multidrug-resistant Salmonella isolate HNK130. HNK130 was isolated from a chicken and identified as ST17 Salmonella enterica serovar Indiana and exhibited resistance to 13 antibiotics including the cephalosporins and fosfomycin. S1 nuclease pulsed-field gel electrophoresis and Southern blot assays revealed that HNK130 harbored only one ∼180-kb plasmid carrying fosA3 and bla _CTX-M-14, which was not transferable via conjugation. We further examined 107 Escherichia coli electro-transformants and identified 3 different plasmid variants, pT-HNK130-1 (69), pT-HNK130-2 (15), and pT-HNK130-3 (23), in which pT-HNK130-1 seemed to be the same a
