Despite the diversity detected in Group A Streptococcus strains from more than 20 countries, investigators narrowed in on broadly shared sequences with relatively low variation.
Researchers identified 34 known and 30 new Leptospira species by sequencing dozens of isolates from soil and water samples in Asia, Africa, Europe, and Oceania.
Genomic data for almost 300 ancient Eurasian horses points to lost equine lineages, horse relationships that reflect human interactions, and a recent loss in genetic diversity.
Using genome sequence data for 429 accessions, an international team tracked chickpea's origin and spread, while identifying markers for important traits.
Based on sequences for hundreds of E. coli ST131 lineage isolates, researchers propose a model that involves negative frequency-dependent selection on accessory parts of the genome.
To understand the evolution of brain conditions and other traits, investigators plan to sequence human and pathogen DNA in thousands of samples from Europe.
Researchers retraced transmission events and resistance contributors with whole-genome sequences for 100 carbapenem-resistant Klebsiella pneumoniae isolates from a Beijing hospital.
There's increasing genetic evidence that a number of ancient hominins may have contributed to the human gene pool, according to Discover's The Crux blog.
