Complete Sequences of IncU Plasmids Harboring Quinolone Resistance Genes qnrS2 and aac(6')-Ib-cr in Aeromonas spp. from Ornamental Fish

. 2016 Jan ; 60 (1) : 653-7. [epub] 20151102

Language English Country United States Media electronic-print

Document type Journal Article, Research Support, Non-U.S. Gov't

The nucleotide sequences of three IncU plasmids from Aeromonas spp. isolated from ornamental fish are described. They had a typical IncU backbone for plasmid replication and maintenance functions, but conjugative transfer modules were disrupted. The gene qnrS2 was inserted into mpR as a mobile insertion cassette. Novel Tn3 family transposons carrying putative toxin-antitoxin and plasmid stability genes were identified. The study demonstrates high plasticity of IncU plasmids from aquatic environments.
