We first took a broad comparative-genomics approach, updating the map of ERs across bacterial diversity by analyzing >40,000 complete genomes. Large ERs tend to converge in GC content toward their host chromosome, recur independently, and are often conserved at the genus level.

Decade-long warming accelerates antibiotic resistance in grassland soils - Nature
Decade-long warming increased soil antibiotic-resistance genes by about 24%, enriching resistant microbes and gene transfer, driven by selection for thermal tolerance and linked traits, with implications for public health.

Bacteria swap DNA far more than we thought. This study shows recombination between species can blur genetic boundaries, with up to 95% of diversity coming from hybrid DNA in some microbes.

Microbes might behave less like distinct species and more like constantly interbreeding communities.

From clonality to complexity: a journey through microbial ecology and evolution
Nature Reviews Genetics, Published online: 30 October 2025; doi:10.1038/s41576-025-00910-6Jaime Martinez-Urtaza reflects on two papers by Smith et al., who found that bacteria exist along a continuum from clonal to recombining populations, and introduced the concept of an ‘epidemic’ microbial population structure.
