Strawberry dietary intervention influences diversity and increases abundances of SCFA-producing bacteria in healthy elderly people.

The gut microbiome is amenable to dietary interventions, and polyphenol-rich diets have been shown to enhance abundances of bacteria associated with short-chain fatty acid (SCFA) production. We examined the effects of a strawberry-based intervention on the gut microbiome of 69 healthy elderly German adults. Participants in five groups consumed varying amounts of strawberries, freeze-dried strawberries, and capers in olive oil over 10 weeks as part of a randomized controlled trial.

Prevalence of autotransporters in Escherichia coli: what is the impact of phylogeny and pathotype?

Autotransporter (AT) proteins are widespread surface-exposed or secreted factors in Escherichia coli. Several ATs have been correlated with pathogenesis or specific phylogenetic lineages. Therefore, an application as biomarkers for individual extraintestinal pathogenic E.
