Similarly to other vertebrates, fish-associated microbiota can be both modulated by host intrinsic factors, such as age (Rosado et al. In fish, the microbiome associated with mucosal tissues forms an integrative part of the immune system (Kelly and Salinas 2017), supporting vital physiological functions such as immune response (de Bruijn et al. Our results also suggest that fish transportation operations may have profound effects on the fish microbiome, but further studies are needed to accurately evaluate their impact.įish microbiome, fish infection, aquaculture, oxytetracycline, Sparus aurata, dysbiosis Introduction The study highlights the negative impacts of disease and antibiotic treatment on the microbiome of farmed fish. The skin and gill microbiomes of diseased fish became largely dominated by taxa that have been frequently linked to secondary infections, whereas in the gut the genus Vibrio, known to include pathogenic bacteria, increased with OTC treatment. Although microbiota response differed between studied tissues, overall changes in composition, diversity, structure, and predicted function were observed in all mucosae. piscicida and subsequent antibiotic treatment with oxytetracycline (OTC), as well as during recovery. Here, we employed a 16S rRNA high-throughput metataxonomics approach to characterize changes in the gut, skin, and gill microbiomes occurring due to infection with Photobacterium damselae subsp. ![]() Pathogen infections greatly affect the production of gilthead seabream, and antibiotic treatment is still frequently required. Diseases and antibiotic administration are known to cause dysbiosis in farmed fish. Several biotic and abiotic factors help maintaining microbial homeostasis, with disruptions leading to dysbiosis. The activity of the microbiome of fish mucosae provides functions related to immune response, digestion, or metabolism.
