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.
