Today’s digest is short and sweet! We have articles on the gut microbiota in rats, the influence of host genetics on the leaf fungal microbiome, and biofilm fouling in drinking water. There are also two manuscripts which provide tips for pathway enrichment analysis and biomarker discovery.

Happy reading! Also, if you’re in Scotland, consider checking out the enormous E. coli in Edinburgh this weekend!

God morgon!

Good morning from Sweden.

Today’s digest has studies from diverse topics but the one that caught my attention is a preprint that addresses the controversial question of presence of a ‘normal blood microbiota’ in humans. The authors of this preprint analysed about 10,000 humans samples and provide evidence that there is no core blood microbiota.

A new preprint describes a unique Taleocin (a bacteriocin) from Pseudomonas syringae which defies the convention that bacteriocins have a narrow spectrum. The bacteriocin has a broad range killing activity against agriculturally important pathogens like Erwinia amylovora and Xanthomonas perforans as well as against the clinical human pathogen Salmonella choleraesuis.

Another preprint reports metabolic interactions responsible for unusually high Iron and lipid content in Geobacter sulfurreducens, a bacterium known iron reducing bacterium in the soil. Another environmental study found that human pathogens are the major carriers of antibiotic resistance genes in the Yangtze river – one of the longest in the world. This is in contrast to prevalent belief that conventional supercarriers are Enterococcus spp. and other fecal indicator bacteria.

Elsewhere in the digest is a preprint from my previous lab where my old colleagues have reported a small RNA and metal dependent mechanism that regulates the survival of Acinetobacter baumannii under oxidative stress.

As a bonus, there is a super intriguing preprint where the authors have actually provided evidence that coming up with creative and funny titles for your papers can help them gain more visibility and citations! So, all of you writing an article or planning to write one soon, this is a great tip!

I hope you will enjoy reading today’s digest and have a great week ahead!
