Gene-specific selective sweeps are pervasive across human gut microbiomes - Nature
Adaptive alleles in gut bacteria evolve rapidly within hosts and spread across hosts via strain transmission and horizontal gene transfer, creating elevated local linkage disequilibrium.
Another Possible Risk of Microplastics? Antibiotic-Resistant Bacteria
Microplastics create dense biofilm habitats that promote bacterial gene exchange, potentially accelerating the spread of antibiotic resistance and threatening human health.
