An ancient genome of Streptococcus pyogenes from a pre-Columbian Bolivian mummy - Nature Communications

Streptococcus pyogenes is a human pathogen responsible for a range of diseases. Here, the authors reconstruct an ancient S. pyogenes genome from a pre-Columbian Bolivian mummy, supporting that the pathogen circulated in the Americas prior to the European contact.
