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!

God morgon! Good morning from Sweden. Today’s digest features only three articles but I am sure everyone will enjoy reading it, especially a super interesting article highlighting the importance of older siblings on development of an individual’s airway and gut microbiota. The study asserts that having a closely aged older sibling has more impact on one’s microbiota as compared to having more than one older sibling. Another featured article demonstrates how gut microbiota can improve the quality of chicken by preventing intestinal inflammation. From animal farming we go over to plant farming. Another article in today’s digest shows how monocropping (growing the same crop over and over) negatively impacts the diversity of soil bacteria which eventually shows up as poor yield. This makes it imperative to consider the soil microbiota while taking decisions on crop cycle. I hope you will enjoy reading today’s digest and have a great week!
