Fossilized feces from ancient Mexico's 'Cave of the Dead Children' have yielded a wealth of information about the intestinal parasites, food, and microbiome of long-dead inhabitants. The analysis of 1,000-year-old dried feces has revealed that intestinal infections from pinworms and Shigella were prevalent among the Loma San Gabriel people who lived in the region around 1,200 to 1,400 years ago.
According to a study published in PLOS One, the unique dry climate and conditions of the cave helped preserve the fossilized feces and other organic materials found at the site. The researchers used a new technique involving qPCR assays to analyze 10 samples, which allowed them to identify specific genes associated with enteric pathogens that were present in the ancient feces.
The findings suggest that intestinal infections and poor sanitation were common among the Loma San Gabriel people, potentially indicating that they had limited access to clean water or proper waste management practices. The high prevalence of gut parasites also suggests that their diet may have been high in certain nutrients, such as protein or fiber, which can promote the growth of pathogenic bacteria.
The study provides a unique insight into the health and well-being of ancient populations and highlights the importance of understanding the microbiome and its relationship to disease. The findings also demonstrate the potential for modern molecular methods to be used in the analysis of ancient samples, providing new avenues for research and discovery.
