Plasmid-mediated florfenicol resistance encoded by the floR gene in Escherichia coli isolated from cattle.
A florfenicol resistance gene almost identical to floR of Salmonella enterica serovar Typhimurium DT104 was detected on 110- to 125-kb plasmids in Escherichia coli isolates of animal origin. Analysis of the floR gene flanking regions of one of the plasmids showed that they were different from those encountered in S. enterica serovar Typhimurium DT104.
