Story summary

Researchers at Stockholm University found bacterial DNA from mammoth remains over 1.1 million years old.
The study, published in *Cell*, analyzed DNA from 483 specimens, identifying six microbial types, including Pasteurella.
Some microbes may have posed health risks similar to those affecting modern elephants.
The findings suggest ancient microbial communities were shaped by their relationship with megafauna.
This research enhances our understanding of extinct species' biology and ecosystems.
