Pompeii victim had spinal tuberculosis when he died
The study also sequenced the victim's entire genome.

The eruption of Mount Vesuvius buried the Roman city of Pompeii in ash in 79 CE. Anthropologists recently sequenced ancient DNA from one of the victims, a man in his late 30s, providing a glimpse into the family background of a Roman citizen.
The results also suggest that he suffered from a tuberculosis infection in his lower spine. In one of the victim’s vertebrae, the study found DNA from the bacterium that causes tuberculosis, suggesting that the infection had traveled through the bloodstream from his lungs to his lower spine.
Pompeii man was Italian
A team led by anthropologist Gabriele Scorrano of the University of Rome sequenced the genome of the victim, which revealed, unsurprisingly, that man was of central Italian descent. Although the ancient man’s genome didn’t yield much new information about life in Pompeii, it proves that bones from Pompeii may still contain enough DNA to sequence—and that could be exciting news.
Even partial genomes from several more Pompeiians could shed some light on the demographics of a cosmopolitan Roman city, where historical documents tell us that people came from all over the Roman Empire (willingly or not). But sequencing ancient DNA from skeletons at Pompeii has been a challenge because high temperatures—like the ones in the pyroclastic flow of superheated volcanic gas and debris that killed everyone in the city—tend to cause chemical changes in bone and damage the DNA inside. Previous studies have managed to sequence only a few short stretches of mitochondrial DNA (which is stored in the meme-famous “powerhouse of the cell” and passed directly from mother to child).
