A multi-drug resistant, CTX-M-65 producing Salmonella Infantis was identified from a patient in Brazil. Whole genome sequencing followed by hybrid assembly (short and long reads) indicated the presence of blaCTX-M-65 in a pESI-like megaplasmid in this ST32 isolate and phylogenetic analysis showed high similarity with IncFIB S. Infantis isolates from food and poultry in the USA.
