COMMENT: Microbiome analysis is a way to know more about physiology and pathology in farm animals for human alimentation. Thus, there is an increasing interest in knowing microbiome of fish, and, in particular, in the economically important farmed fish species such as rainbow trout Oncorhynchus mykiss as the authors stated.
The authors reported that:
The results of this research have revealed that the overall structure of the microbiome between the farm and aquarium raised fish analysed in this study was very similar, however the community membership was significantly different between the two populations
The genus Mycoplasma was the most dominant genus, and the authors hypothesized that:
The pattern of dominance of this microbe, in conjunction with its streamlined genome, is suggestive of an obligate symbiotic relationship with the rainbow trout intestine
