Abstract The microbiome of the host and its surroundings play a vital role in health well‐being. Unlike terrestrial organisms that maternally acquire microbiome, aquatic species mainly get colonized by microorganisms surrounding are exposed to wide variety microbial community based on type environment inhabits. This review is focused aquaculture shrimp factors influence such as prebiotics, probiotics, synbiotics, diet, stress conditions, frequency antibiotics used, physiological conditions developmental stages. also casts light enhancing health, immune response, colonization, effects biofloc system microbiome. Moreover, beneficial microbes can be safer alternative harmful used aquaculture, which thereby prevent emergence superbugs enhance production rate. A proper understanding interactions between help us modulate manipulate organisms, ensures growth industry. Therefore, treatment strategies should targeted towards modulation acts partners overcome challenges confronted sector.

Advances in Microbiome Research for Animal Health

Annual Review of Animal Biosciences, Journal Year: 2020, Volume and Issue: 9(1), P. 289 - 311

Published: Dec. 15, 2020

Host-associated microbiomes contribute in many ways to the homeostasis of metaorganism. The microbiome's contributions range from helping provide nutrition and aiding growth, development, behavior protecting against pathogens toxic compounds. Here we summarize current knowledge diversity importance microbiome animals, using representative examples wild domesticated species. We demonstrate how beneficial ecological roles animal-associated can be generally grouped into well-defined main categories microbe-based alternative treatments applied mitigate problems for both economic conservation purposes crucial about host-microbiota symbiotic interactions. suggest a Customized Combination Microbial-Based Therapies promote animal health practice sustainable husbandry. also discuss connections threats associated with biodiversity loss, microorganism extinction, emerging diseases, such as COVID-19 pandemic.

Fish Skin and Gut Microbiomes Show Contrasting Signatures of Host Species and Habitat

Applied and Environmental Microbiology, Journal Year: 2020, Volume and Issue: 86(16)

Published: June 4, 2020

Teleost fish represent an invaluable repertoire of host species to study the factors shaping animal-associated microbiomes. Several studies have shown that phylogenetic structure gut microbiome is driven by species-specific (e.g., ancestry, genotype, or diet) and habitat-specific hydrochemical parameters bacterioplankton composition) factors. However, our understanding other host-associated microbial niches, such as skin mucus microbiome, remains limited. The goal was explore simultaneously compare effect species- drivers on communities in both tissues. We sampled 114 wild from 6 populations 3 ecologically phylogenetically contrasting Amazonian teleost species. Water samples were collected at each site, 10 physicochemical characterized. mucus, gut, water characterized using a metabarcoding approach targeting V3-V4 regions 16S rRNA. Our results showed significant distinction between profile diversity niche. Skin significantly closer composition than free-living communities. Species-specific mostly modulated bacterial communities, while predominantly associated with environmental physicochemistry community structure. These suggest variable relevant target for development biomarkers status, more conserved better suited long-term host-microbe interactions over evolutionary time scales.IMPORTANCE Whether microbiomes are shaped still unresolved. In particular, it unknown what extent two different tissues same respond these one first focus shed light this topic we investigate how distinct contrast highly environment dependent. This result has various implications: (i) should be used, rather ecosystem perturbance wild, (ii) phylosymbiosis, coevolution their symbionts.

Neutral Processes Dominate Microbial Community Assembly in Atlantic Salmon, Salmo salar

Applied and Environmental Microbiology, Journal Year: 2020, Volume and Issue: 86(8)

Published: Feb. 4, 2020

A growing number of studies have examined variation in the microbiome to determine role modulating host health, physiology, and ecology. However, ecology microbial colonization is not fully understood rarely tested. The continued increase production farmed Atlantic salmon, coupled with increased farmed-wild salmon interactions, has accentuated need unravel potential adaptive function distinguish resident from transient gut microbes. Between compartments a system, we found majority operational taxonomic units (OTUs) that fit neutral model, Mycoplasma species among key exceptions. In wild fish, deterministic processes account for more OTU differences across life stages than those observed compartments. Unlike previous studies, our results make detailed comparisons between fish environments, while also providing insight into ecological underpinning community assembly this ecologically economically important species.

Effects of disease, antibiotic treatment and recovery trajectory on the microbiome of farmed seabass (Dicentrarchus labrax)

Scientific Reports, Journal Year: 2019, Volume and Issue: 9(1)

Published: Dec. 12, 2019

Abstract The mucosal surfaces of fish harbour microbial communities that can act as the first-line defense against pathogens. Infectious diseases are one main constraints to aquaculture growth leading huge economic losses. Despite their negative impacts on diversity and overall health, antibiotics still method choice treat many such diseases. Here, we use 16 rRNA V4 metataxonomics study over a 6 week period dynamics gill skin microbiomes farmed seabass before, during after natural disease outbreak subsequent antibiotic treatment with oxytetracycline. Photobacterium damselae was identified most probable causative agent disease. Both infection caused significant, although asymmetrical, changes in microbiome composition gills skin. dramatic taxonomic abundance occurred between healthy diseased fish. Disease led decrease bacterial core skin, whereas there both an increase shift diversity. Oxytetracycline Severe loss mucosae demonstrates disruptive impact

Commensal bacteria‐immunity crosstalk shapes mucosal homeostasis in teleost fish

Abstract Fish harbour complex and dynamic microbiota in their mucosal surfaces. Due to the vital role of commensal many biological functions including growth enhancement, nutrition, development, metabolism immune response, scholars have begun refer microbiome as an ‘extended self’. Several studies indicated that a normal contributes fish health, disturbances microbial communities may lead secondary infections disease. Under evolutionary selective forces, developed excellent innate mechanisms adaptive system composed B cells T discriminate between beneficial opportunistic bacteria for homeostasis. Many functional demonstrated involvement cells, cytokines Igs maintaining homeostasis, microbes contribute improving barrier against external threats. Additionally, host‐derived probiotics been empirically used aquaculture sector provide effective protection diseases. Although little is known about interactions compared mammals, managing represent promising alternative antibiotics disease prevention control. This review thus provides updated comprehensive summary currently characterized microbe compositions tissues. Thereafter, current knowledge on crosstalk application also discussed herein, thereby providing theoretical basis development microbe‐based control technologies aquaculture.

Rice protein concentrate as a fish meal substitute in Oreochromis niloticus: Effects on immune response, intestinal cytokines, Aeromonas veronii resistance, and gut microbiota composition

Fish & Shellfish Immunology, Journal Year: 2022, Volume and Issue: 126, P. 237 - 250

Published: May 30, 2022

The potential of rice protein concentrate (RPC) to substitute fishmeal (FM) in the diet Oreochromis niloticus was assessed a five-month-long feeding trial. Fishmeal replaced by RPC at rates 0% (control), 25%, 50%, and 75% (RPC0, RPC25, RPC50, RPC75, respectively). RPC25 had no significant effect on antioxidant capacity (total capacity; superoxide dismutase, catalase, glutathione peroxidase activities) immune indices (lysozyme, nitric oxide, antiprotease, bactericidal after one, two, five months feeding, while values for these parameters were significantly lower RPC75 group compared those RPC0 group. showed higher mRNA levels intestinal cytokines IL-1β, IL-10β, TGF-β, TNF-α than control In fish affected Aeromonas veronii, highest cumulative mortality recorded group, followed groups. Gut microbiome analyses reduction microbial diversity response addition RPC, regardless content, composition community samples differed from that control.
