Comparative performance of reference-based metagenomic tools to identify species-level taxa among families of bacteria: benchmarking Mycobacteriaceae and Neisseriaceae

This study benchmarks reference-based metagenomic tools for species-level detection in closely related bacterial families, finding metapresence and sylph perform best.

Biosurfactant polysaccharide drives dispersal of exopolysaccharide-coated myxospores in Myxococcus xanthus

The paper identifies the role of biosurfactant polysaccharide in regulating myxospore dispersal by reducing surface stickiness, while revealing the true outermost coat as exopolysaccharide.

Host adaptation drives genome evolution and virulence diversification in a bacterial zoonotic pathogen

The paper examines how host adaptation influences genome evolution and virulence in Leptospira interrogans, showing distinct genetic and regulatory changes in rodent- and cattle-associated lineages.

Phenotypic plasticity in bacterial elongation among closely related species

The paper reveals diverse cell elongation mechanisms in closely related bacterial species using fluorescent D-amino acids and shows phenotypic plasticity in elongation complexes.

Evolutionary insights into the emergence of virulent Leptospira spirochetes

This study identifies genetic and phenotypic traits associated with virulence in Leptospira by comparing environmental and pathogenic strains.
