Making yogurt with the ant holobiont uncovers bacteria, acids, and enzymes for food fermentation

The paper investigates ant yogurt fermentation, identifying bacteria, acids, and enzymes from ants that contribute to milk fermentation.

Neonatal infection with Helicobacter pylori affects stomach and colon microbiome composition and gene expression in mice

This study investigates how neonatal H. pylori infection in mice affects stomach and colon microbiome composition and gene expression during the first month of life.

Host age at experimental Helicobacter pylori infection shapes epithelial development of mouse gastric organoids

This study shows that infecting mice with Helicobacter pylori at a young age leads to larger gastric organoids and alters cell type composition compared to adult infection.

Evolutionary genomics reveals plant-associated origins of acetic acid bacteria in fermented food

This study traces the evolutionary origins of acetic acid bacteria, showing they transitioned from plant-associated lifestyles to fermented foods, not from social insect hosts.

Early-life Helicobacter pylori infection in mice alters endocrine signaling and accelerates adipose expansion during high-fat feeding

This study shows that early-life H. pylori infection in mice increases visceral adiposity and alters endocrine and inflammatory responses to high-fat feeding.
