Ancient DNA provides clues to intestinal parasites that plagued early Mexico

Researchers have uncovered new insights into the intestinal parasites that affected early Mexican populations by analyzing ancient DNA from dried feces dating back more than 1,000 years.

The study, published in PLOS One, was led by Drew Capone from Indiana University and his colleagues. By examining preserved samples, scientists were able to identify the pathogens that were common in ancient times, providing a window into the health challenges faced by early Mesoamerican societies.

This discovery not only helps us understand the disease burden in ancient Mexico but also contributes to our knowledge of the co-evolution of humans and parasites. By identifying the specific parasites present in the past, researchers can better trace how these infections have changed over time and their impact on human populations.

The findings may also inform current public health efforts. Understanding the long-term history of parasitic infections can help public health officials identify patterns and potentially develop more effective strategies for controlling these diseases today.

The study demonstrates the potential of using ancient DNA to study health and disease in historical populations, opening new avenues for research into the health challenges of the past.
