The genome sequence of an oxytetracycline-resistant isolate of the fish pathogen Piscirickettsia salmonis harbors a multidrug resistance plasmid

Abstract

The amount of antibiotics needed to counteract frequent piscirickettsiosis outbreaks is a major concern for the Chilean salmon industry. Resistance to antibiotics may contribute to this issue. To understand the genetics underlying Piscirickettsia salmonis-resistant phenotypes, the genome of AY3800B, an oxytetracycline-resistant isolate bearing a multidrug resistance plasmid, is presented here.
