Sumario:The aim of the present study was to identify major bacteria associated with the swim bladder in the rainbow trout, Oncorhynchus mykiss. We extracted DNA from the swim bladder and gut contents in order to perform a temporal temperature gradient gel electrophoresis (TTGE) analysis of 16S rRNA amplicons for bacterial identification to further compare both profiles. Arthrobacter and Cellulosimicrobium were the major genera observed in the swim bladder in fish, but were not present in fish gut contents; Mycoplasma were instead observed in these samples. Further research to investigate the possible symbiotic roles of the swim bladder-associated microbiota in salmonids is needed.
