Abstract

ABSTRACT Two Salmonella enterica serovar Typhimurium strains from different clonal origins, both producing an extended-spectrum β-lactamase (TEM-52), were isolated from a patient. This enzyme was encoded on a single plasmid and was found at very low levels in one strain, while being encoded on multiple plasmids and in multiple different Eco RI fragments in the other strain.
