Gut microbiome signatures of vegan, vegetarian and omnivore diets and associated health outcomes across 21,561 individuals - Nature Microbiology Using 21,561 individuals, the authors present a cross-sectional study of how gut microbiome signatures are associated with dietary intake patterns and with host health outcomes.

Stable isotope fingerprinting can directly link intestinal microorganisms with their carbon source and captures diet-induced substrate switching in vivo Diet has strong impacts on the composition and function of the gut microbiota with implications for host health. Therefore, it is critical to identify the dietary components that support growth of spe...

This is figure 4, which shows collateral sensitivity and cross-resistance interactions between and within antibiotic classes.

Resistance to one antibiotic can make bacteria resistant or sensitive to another antibiotic, opening paths for combinatorial treatments. A study in Nature Microbiology presents an approach to systematically discover and understand such antibiotic relationships. https://go.nature.com/49of3Mk 🧪

A study in Scientific Reports finds that both high fruit and high vegetable intake were associated with lower depressive symptoms in people over 45 years old. Only moderate vegetable intakes were associated with lower depressive symptoms. https://go.nature.com/3ZDOIGL 🧪

Geographical variation in the incidence of colorectal cancer and urinary tract cancer is associated with population exposure to colibactin-producing Escherichia coli Biomedical research has implicated the bacterial metabolite colibactin as a causal risk factor for several cancer types, in particular, colorectal can…

New paper:

We show that population exposure to colibactin producing E. coli lineages ST95 and ST73 largely explains global variation in colorectal cancer incidence. Same STs are also major causes of UTIs and may be similarly involved in urinary tract cancers.
