Red mark syndrome: Is the aquaculture water microbiome a keystone for understanding the disease aetiology? / A. Bruno, A. Cafiso, A. Sandionigi, A. Galimberti, D. Magnani, A. Manfrin, G. Petroni, M. Casiraghi, C. Bazzocchi. - In: FRONTIERS IN MICROBIOLOGY. - ISSN 1664-302X. - 14:(2023 Feb 27), pp. 1-13. [10.3389/fmicb.2023.1059127]
Abstract:
Aquaculture significantly contributes to the growing demand for food worldwide.
However, diseases associated with intensive aquaculture conditions, especially
the skin related syndromes, may have significant implications on fish health and
industry. In farmed rainbow trout, red mark syndrome (RMS), which consists of
multiple skin lesions, currently lacks recognized aetiological agents, and increased
efforts are needed to elucidate the onset of these conditions. Most of the past
studies were focused on analyzing skin lesions, but no study focused on water, a
medium constantly interacting with fish. Indeed, water tanks are environmental
niches colonized by microbial communities, which may be implicated in
the onset of the disease. Here, we present the results of water and sediment
microbiome analyses performed in an RMS-affected aquaculture facility, bringing
new knowledge about the environmental microbiomes harbored under these
conditions. On the whole, no significant differences in the bacterial community
structure were reported in RMS-affected tanks compared to the RMS-free ones.
However, we highlighted significant differences in microbiome composition
when analyzing different samples source (i.e., water and sediments). Looking at
the finer scale, we measured significant changes in the relative abundances of
specific taxa in RMS-affected tanks, especially when analyzing water samples.
Our results provide worthwhile insight into a mostly uncharacterized ecological
scenario, aiding future studies on the aquaculture built environment for disease
prevention and monitoring.
