Shalom from Israel and a Happy world microbiome day!

Yes, it is a true day! celebrating the huge diversity of microbes around us, above us, below us and inside us. Check the day’s official website for more information, and take the weekend to appreciate this amazing field and your own personal contribution to advancing our knowledge about microbial communities on our planet.

Personally, I did my undergrad in Ecology and Evolution, confidence that I’ll my scientific career will focus on plant ecology and distribution, or at least large animals. Microbiology classes and introduction labs bored me, and I did my best to avoid this topic. But all of a sudden, during my Master’s degree (where I worked on a pathogenicity mechanism of postharvest disease-causing bacteria), I fell in love with microbiology in general, and specific bacterial communities. The huge untapped diversity, the unbelievable functions and the amazing interactions needed to maintain a functional community of these invisible inhabitants just fascinated me. Today, as a Ph.D. student exploring secondary metabolites gene clusters in soil and root microbiome, I’m a super-fan of the bacterial world.

How did you end up being microbiome suckers? Feel free to share your stories here as a comment, on MD FB page, or directly on tweeter.

Today’s digest include several microbimoe papers of animal midels (including ‘dirty mice’), diseased tomatoes taxonomical and functional microbiome profile, AND- a sweet reminder of the pre-COVID-19 world, with an analysis of the dust microbiome of a plane (remember this vehicle?).

Non-human microbiome, June 17

You waited for it: the Cannabis microbiome! But also microbiotas of salmon, a quail, coral, sponges, water, and ice.

Bird microbiome

Cultivable Bacterial Microbiota of Northern Bobwhite (Colinus virginianus): A New Reservoir of Antimicrobial Resistance? – Hongwen Su – PLOS ONE

“Firmicutes was the most commonly encountered phylum (57%) followed by Actinobacteria (24%), Proteobacteria (17%) and Bacteroidetes (0.02%). Extensive diversity in the species composition of quail microbiota was observed among individual birds and anatomical locations.”

Fish microbiome

Pyrosequencing-based characterization of gastrointestinal bacteria of Atlantic salmon (Salmo salar L.) within a commercial mariculture system – K.Z. Zarkasi – Journal of Applied Microbiology

“Salmon GI tract bacterial communities commercially farmed in south-eastern Tasmania were analysed, over a 13-month period across a standard commercial production farm cycle, using 454 16S rRNA-based pyrosequencing. “

Coral and sponge microbiome

Community Shifts in the Surface Microbiomes of the Coral Porites astreoides with Unusual Lesions – Julie L. Meyer – PLOS ONE

“The presence of lesions in P. astreoides coincided with a decrease in the relative abundance of Endozoicomonas, rather than the appearance of specific pathogenic taxa.”

Bacterial suspects identified in Caribbean coral deaths – NewScientist

“Three bacteria seem to be responsible for a disease that has killed most of the Caribbean’s reef-building corals.”

Effects of salinity on antibiotic production in sponge-derived Salinispora actinobacteria – Y.K. Ng – Journal of Applied Microbiology

Fingerprint data were generated from extracts of S. arenicola broth cultures grown in media of varying salt (NaCl) concentrations.”

Plants microbiome

Understanding Cultivar-Specificity and Soil Determinants of the Cannabis Microbiome – Max E. Winston – PLOS ONE

“Here we present the first description of the endorhiza-, rhizosphere-, and bulk soil-associated microbiome of five distinct Cannabis cultivars. Bacterial communities of the endorhiza showed significant cultivar-specificity.”

The Role of Abiotic Environmental Conditions and Herbivory in Shaping Bacterial Community Composition in Floral Nectar – Michal Samuni-Blank – PLOS ONE

“ We studied culturable bacterial communities in Asphodelus aestivus floral nectar and in its typical herbivorous bug Capsodes infuscatus, along an aridity gradient.”

Microbial community structure during fluoranthene degradation in the presence of plants – S. Storey – Journal of Applied Microbiology

“Bacterial and fungal community composition in the rhizosphere was significantly different from that in nonrhizospheric and unplanted samples.”

Soil microbiome

Omics-based interpretation of synergism in a soil-derived cellulose-degrading microbial community – Yizhuang Zhou – Scientific Reports

“Analyses of reconstructed bacterial draft genomes from all seven uncultured phylotypes in F1RT indicate that its constituent microbes cooperate in both cellulose-degrading and other important metabolic processes.”
