A holistic view of host-associated microbial evolution

Dispersal strategies shape persistence and evolution of human gut bacteria

Falk Hildebrand et al.

Summary: Human gut bacterial strains can persist for decades in individuals, families, and geographic regions, with locally successful strains of Bacteroidota showing high levels of genetic adaptation. By contrast, Firmicutes rely on weak phylogeographic patterns but strong family transmissions, likely related to sporulation. These analyses provide insights into long-term persistence of gut microbes and the implications for gut flora modulations.

Modeling host-associating microbes under selection

Florence Bansept et al.

Summary: The study shows that microbes can adapt to a two-compartment life cycle by changing either replication rates or migration rates, depending on the initial values of traits, the initial distribution across the two compartments, the intensity of competition, and the time scales involved.
