A cross-environment comparison of nontuberculous mycobacterial diversity
Nontuberculous mycobacteria (NTM) are a group of environmental bacteria that encompass nearly 200 described species, some of which can cause chronic pulmonary infection in humans. What makes these inf...

New preprint led by Matt Gebert focused on the environmental reservoirs of nontuberculous mycobacterial (NTM) pathogens. NTM disease is environmentally acquired, but routes of exposure unclear. Our work implicates premise plumbing as the main culprit! www.biorxiv.org/content/10.1...

After 15 years, the authors of the infamous 'arsenic life' paper are still trying to argue that their findings are legit and not just a product of 'major errors'? Unbelievable. The authors' response to the retraction is infuriating. Time to let it go. www.science.org/doi/10.1126/...

We hope the approach and our draft 'periodic table' are useful and encourage future efforts to systematically characterize trait variance across the bacterial tree of life.(6/6)

Perhaps more importantly, the workflow for generating the 'periodic table' is adaptable so it can ultimately be expanded to incorporate additional traits/taxa (5/6).

Our draft 'periodic table' of bacterial diversity, like the periodic table of the elements, provides a interpretable & concise way to visualize and explore bacterial diversity in trait space (see Figs 4-5) - linking phylogeny to trait distributions in a quantifiable manner (4/6)

Here we focused on 6 traits - inferring those traits (including autotrophy, O2 tolerance, phototrophy, etc.) using genome-based models across >50,000 bacterial 'species' (thanks @ace-gtdb.bsky.social!) (3/6)

Work was motivated by the challenges associated with linking taxonomic/phylogenetic information to knowledge of what we know (or think we know) about bacterial traits (2/6)

A periodic table of bacteria?: Mapping bacterial diversity in trait space
Bacterial diversity can be overwhelming. There is an ever-expanding number of bacterial taxa being discovered, but many of these taxa remain uncharacterized with unknown traits and environmental prefe...

I agree with both of these papers. Given that they were published >10 years ago, why is the 'hologenome' concept still a thing?

Correct - if you filtered a few liters of your saliva for DNA extraction, you would undoubtedly have far far higher DNA yields than a few liters of household water

Continent-wide assessment of the strain-level diversity of Bradyrhizobium, a dominant soil bacterial genus
Global surveys of soil bacteria have identified several taxa that are nearly ubiquitous and often the most abundant members of soil bacterial communities. However, it remains unclear why these taxa ar...

New study out - we developed a pipeline for targeted assembly of genomes from (complex) soil metagenomes to examine the strain-level diversity and ecology of a dominant soil bacterial genus (Bradyrhizobium). Feedback appreciated. www.biorxiv.org/content/10.1...

Just your regular reminder that 'sterile' doesn't mean 'DNA-free'! (this rant brought to you by yet another published DNA-based study conducted in a low biomass system where appropriate controls do not appear to have been included)

Dear fellow olds - recognize that the term 'next generation sequencing' is confusing to those that never had experience with the first generation. Also - what 'generation' are we on anyways?
