Bacterii din intestinul oamenilor au călătorit cu ei de mii de ani | Unele dispar însă din lumea modernă

A recent study published in Nature reveals that the gut microbiomes of the Tsimane in Bolivia and the Hadza in Tanzania share a significant number of ancient microorganisms. Despite being separated for thousands of years, both populations have 1,231 common microbial species, many of which are rare in industrialized societies. The research indicates that these microorganisms have been associated with humans for over 10,000 years, raising concerns about the loss of these species due to lifestyle changes. The study highlights the potential health implications of this loss, although it does not establish direct links to specific diseases. Researchers emphasize the importance of considering indigenous communities in future microbiome studies.
