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.
By studying koalas and a retrovirus that infects them, researchers may have uncovered a new sort of 'immune response' that occurs at the genomic level, Agence France Presse reports.
