This plasmid exhibited a broader host range and a generally higher transfer frequency when compared to the promiscuous plasmid RP4 originating from a hospital isolate of Pseudomonas aeruginosa. The plasmid pRAS1 was transferred from A. salmonicida to unrelated bacterial species and even to a Gram-positive bacterium (Lactobacillus sp.). Transfer of the plasmid was also shown to occur between A. salmonicida and 6 different bacterial isolates from fish farm sediments. Aquaculture . Antibiotic resistance .
