The bacterium responsible for #scarletFever was not introduced to the Americas by Europeans.
A research team led by Eurac Research has identified the #Streptococcus pyogenes bacterium in a pre-Columbian Bolivian mummy and, for the first time, reconstructed the genome of this centuries-old pathogen.

The bacterium responsible for scarlet fever was not introduced to the Americas by Europeans.

Researchers identified the pathogen’s genetic material while examining a tooth from a naturally mummified skull housed at MUNARQ – the National Museum of Archaeology in La Paz. Using a method that reassembles previously unknown genomes from numerous short DNA fragments, they reconstructed a nearly complete, ancient genome of Streptococcus pyogenes. The reconstructed genome shows clear similarities to modern strains of the globally widespread bacterium, which can cause a variety of illnesses ranging from harmless throat infections to scarlet fever and life-threatening toxic shock syndrome. Despite the pathogen’s great medical significance: scarlet fever was historically one of the leading causes of death among children, little is known about its evolutionary history. This finding now shows that the bacterium was already circulating among indigenous populations in South America before European colonization: the young man from whom the tooth originated lived between 1283 and 1383 AD. The study was made possible by a cooperation agreement between Eurac Research and the Bolivian Ministry of Cultures and has been published in Nature Communications.

Vancouver quartet Scarlet Fever releases their debut album, girl with shank, on November 1, 2025, via play dead. The indie rock album is a coming-of-age conceptualization, exploring young adulthood in a post-pandemic, social media-focused society. The band has honed a sound that pairs 90s-style blown-out riffs with undeniable pop sensibility, capturing the emotional intensity of their growing reputation on the West Coast DIY circuit.
