An animals’ body is densely populated with bacteria. Although a large number of investigations on physiological microbial colonisation have emerged in recent years, our understanding of the composition, ecology and function of the microbiota remains incomplete. Here, we investigated whether songbirds have an individual-specific skin microbiome that is similar across different body regions. We collected skin microbe samples from three different bird species (Taeniopygia gutatta, Lonchura striata… 

Family matters: skin microbiome reflects the social group and spatial proximity in wild zebra finches

The skin microbiome of wild zebra finches is characterised and it is found that animals of social groups (families) harbour highly similar bacterial communities on their skin with respect to community composition, and that spatial proximity of nest sites, and therefore individuals, correlated with the skin microbiota similarity.

The Gut Microbial Composition Is Species-Specific and Individual-Specific in Two Species of Estrildid Finches, the Bengalese Finch and the Zebra Finch

This study conclusively shows that host-specific factors contribute structuring of gut microbiota, and that within-individual variation in microbial communities was larger in males of both species.

The skin microbiome of vertebrates

Studies that have leveraged high-throughput sequencing to better understand the skin microorganisms that associate with members of classes within the subphylum Vertebrata are summarized and links between the skin microbiome and vertebrate characteristics are explored.

Drivers of gut microbiome variation within and between groups of a wild Malagasy primate

It is found that group members share more similar gut microbiota and differ in alpha diversity, while none of the environmental predictors explained the patterns of between-group variation, while maternal relatedness played an important role in within-group microbial homogeneity.

The Epidermal Microbiome Within an Aggregation of Leopard Sharks (Triakis semifasciata) Has Taxonomic Flexibility with Gene Functional Stability Across Three Time-points.

It is suggested the leopard shark microbiomes exhibit functional redundancy and coexistence of microbes hosted in elasmobranch microbiomes that encode genes involved in utilizing nitrogen, but not fixing nitrogen, degrading urea, and resistant to heavy metal.

Microbial composition of enigmatic bird parasites: Wolbachia and Spiroplasma are the most important bacterial associates of quill mites (Acari: Syringophilidae)

Findings are interpreted as evidence for a scarcity or lack of resident microbial associates (other than inherited symbionts) in quill mites, or for abundances of these taxa below the authors' detection threshold.

Unveiled feather microcosm: feather microbiota of passerine birds is closely associated with host species identity and bacteriocin-producing bacteria

This study provides the first thorough evaluation of antimicrobial peptides-producing bacterial communities inhabiting the feather integument, including their likely potential to mediate niche-competition and to be associated with functional species-specific feather microbiota in avian hosts.

Microbial composition of enigmatic bird parasites: Wolbachia and Spiroplasma are the most important bacterial associates of quill mites (Acariformes: Syringophilidae)

An unbiased 16S rRNA gene amplicon sequencing approach is used to determine other bacteria that potentially impact quill mite biology and identifies Anaplasma phagocytophilum and a high diversity of Wolbachia strains.

The call of the wild: using non-model systems to investigate microbiome-behaviour relationships.

The value of conducting hypothesis-driven research in non-model organisms and the benefits of a comparative approach that assesses patterns across different species or taxa are highlighted.

Olfactory Communication via Microbiota: What Is Known in Birds?

This review aims to summarize existing knowledge of the factors influencing the microbial communities and the effect of microbiota on olfactory cue production and social and communicative behaviour in avian taxa and non-avian species.

High diversity of skin-associated bacterial communities of marine fishes is promoted by their high variability among body parts, individuals and species.

It is demonstrated that fish surfaces host highly diverse bacterial communities, whose composition was very different from that of surrounding bacterioplankton, supported by the important variability, between host species, individuals and the different body parts.

Humpback whales harbour a combination of specific and variable skin bacteria.

Two components of the whale skin bacterial community are described: a specific and potentially co-evolved fraction, and a more variable microbial community fraction that may offer a diagnostic-type tool for investigating the health and life-related events of these endangered animals.

Microbiome Variation Across Amphibian Skin Regions: Implications for Chytridiomycosis Mitigation Efforts

Skin microbiomes of wild and captive fire-bellied toads were examined for differences across their body surface and found that bacterial communities differed between ventral and dorsal skin, suggesting that bacterial community structure is influenced by microhabitats associated with skin regions.

Diversity of the skin microbiota of fishes: evidence for host species specificity.

Analysis of skin microbiota of Gulf of Mexico fishes showed that the Proteobacteria was the predominant phylum in skin microbiota, followed by the Firmicutes and the Actinobacteria, which provided evidence for the existence of specific skin microbiota associated with particular fish species.

The first deep metagenomic analysis of the vulture microbiome is reported, showing a strong adaption of vultures and their bacteria to their food source, exemplifying a specialized host-microbial alliance.

Bacterial Community Variation in Human Body Habitats Across Space and Time

The results indicate that the microbiota, although personalized, varies systematically across body habitats and time; such trends may ultimately reveal how microbiome changes cause or prevent disease.

Topographic diversity of fungal and bacterial communities in human skin

It is demonstrated that physiologic attributes and topography of skin differentially shape these two microbial communities, which provide a framework for future investigation of the contribution of interactions between pathogenic and commensal fungal and bacterial communities to the maintainenace of human health and to disease pathogenesis.
