The external mucosal microbiomes of fish act as a first line of defence for maintaining host health. However, how skin and gill microbiomes differ between healthy and naturally infected tilapia remains poorly understood. Here, we employed 16S rRNA and 18S rRNA high-throughput metabarcoding to characterise the microbiome of tilapia skin, gills, and water from ponds reported with diseased and non-diseased conditions, and to investigate signatures of microbial dysbiosis related to health conditions.</p><p><strong>Results: </strong>Microbial diversity varied significantly across different sample types (gill, skin and pond water) and geographical locations. Skin and gill microbiomes from reported non-diseased conditions differed in the presence of the commensal genus Cetobacterium, while diseased gill-skin were enriched with pathogenic genera including Flavobacterium, Aeromonas, Vibrio, Vogesella, and Klebsiella. Additionally, the relative abundance of diatom Cyclotella in pond water under diseased conditions appeared to be almost double that of non-diseased pond water, albeit this was statistically non-significant. Cetobacterium formed a core component of the bacterial genera in the non-diseased gill and skin microbiome. In contrast, Aeromonas formed a core component of the core microbiome in the diseased gill and skin microbiomes. Analysis of the microbial co-occurrence network in the diseased skin and gill found it to be relatively less complex compared with these tissues in the non-diseased state.</p><p><strong>Conclusions: </strong>The findings show that the tilapia microbiome differs across the skin and gill tissue surfaces, and from the pond waters in which they are cultured. In reported diseased cases, these microbiomes show enrichment of potential pathogenic genera and less complex microbial co-occurrence networks, which may be used as an indicator of microbial dysbiosis in aquaculture systems.

We aimed to longitudinally characterise the gut microbiota and its development in Labrador Retriever puppies and identify whether alterations in the gut microbiota are associated with factors related to demography, lifestyle, antibiotic usage and gastrointestinal health.</p><p><strong>Results: </strong>76 Labrador Retriever puppies were recruited via Dogslife, a UK-based online cohort study. Faecal samples were collected at three to four, seven, and 12 months of age and analysed using 16 S rRNA gene sequencing alongside questionnaire data. Alpha and beta diversity were assessed using linear mixed effects models and permutational multivariate analysis, accounting for repeated measures. Differential abundance was evaluated using multivariable association with linear models. Associations were identified between puppies' gut microbiota and age, sex, coat colour, household smoking status, dietary indiscretions (e.g. household waste, coprophagia), contact with other dogs and horses, recent oral/injected antibiotic use, and recent vomiting and diarrhoea. The greatest source of variation was individual identity, explaining approximately 25% of alpha diversity and 50% of beta diversity. Alpha diversity declined between three and 12 months, with age-related shifts in community composition and dispersion. Coprophagia was associated with increased alpha diversity and contributed to variation in community structure. Antibiotic use was associated with reduced alpha diversity, altered composition, and changes in taxa across Firmicutes, Proteobacteria, and Tenericutes. These effects were largely transient, with the largest shifts occurring within one week of treatment. Puppies with recent diarrhoea showed increased alpha diversity and differential abundance in several taxa within four weeks of the episode.
