I have not been keeping up with my review of the latest news. It’s time to do some catch-up. This covers news from July and August.
-
- The most interesting is this study looking at the bacteriocins (antibiotics produced by bacteria against other bacteria)

- Small intestine bacteria key in fat uptake, suggests mouse data
- A Dietary Fiber-Deprived Gut Microbiota Degrades the Colonic Mucus Barrier and Enhances Pathogen Susceptibility [src]
- Consuming 25 grams of cricket powder per day may alter specific populations of beneficial gut bacteria, a double-blind, randomized crossover trial conducted at Colorado State University indicated. [src]
- High Dose Vitamin D supplementation alters faecal microbiome and predisposes mice to more severe colitis [src]
- “Drinking tart cherry juice may improve gut health, says new study (5 days, 8 oz. daily) “[src] NOTE: Difference of impact:
” In the human study, two distinct and inverse responses to tart cherry consumption were associated with initial levels of Bacteroides. High-Bacteroides individuals responded with a decrease in Bacteroides and Bifidobacterium, and an increase of Lachnospiraceae, Ruminococcus and Collinsella. Low-Bacteroides individuals responded with an increase in Bacteroides or Prevotella and Bifidobacterium, and a decrease of Lachnospiraceae, Ruminococcus and Collinsella.” - Lactobacillus murinus could protect against the damaging effects of a high-salt diet.

- ” by feeding indigestible starch, involved a species that cannot itself degrade the starch (Bifidobacterium animalis) but cohabits with a species that can (Bifidobacterium pseudolongum). B. pseudolongum has the characteristics of a keystone species in the community because it had low abundance but high ability to perform a critical function, the hydrolysis of resistant starch.” [src]
- Scientific Analysis Shows Probiotic Use is Associated with Fewer Antibiotic Prescriptions [src]
- ” the mechanisms that gut bacterial species use to jostle for space and resources and maintain their populations in the face of intense and varied competition. Bacteria have evolved a range of antibiotics, bacteriocins, toxins, and delivery devices to enable interspecies conflict. These interbacterial weapons possess a spectrum of specificities and range from those that target strains of their own species to broad-acting bacteriocides.” [src]

- A new study has shown that a single genetic change in a bacterium of the gut microbiome can lead to metabolic diseases such as obesity. [src]
