Fatal bacteria which ravaged Napoleons army during…
Scientists say they’ve found traces of the lethal pathogens that ravaged Napoleon’s troopers during his doomed 1812 retreat from Russia — offering a clearer image of the circumstances of the French normal’s downfall.
A research printed in the journal Current Biology on Nov. 3 analyzed DNA from the enamel of French troopers who had been buried in a mass grave in Vilnius, Lithuania.
The troopers served under Napoleon during his disastrous invasion of Russia in the winter of 1812. They had been among the roughly 300,000 French Grande Armée troopers who perished in the marketing campaign.
The enamel contained bacteria that causes paratyphoid fever and louse-borne relapsing fever, said the researchers — indicating that a number of infections circulated among the troopers who had been weakened by starvation and the freezing temperatures.
These two pathogens had not been recognized beforehand among Napoleon’s troopers, though historians have documented the tough circumstances of their deaths for over two centuries.

Study writer Nicolás Rascovan, talking to GWN, said Vilnius “was a key waypoint on the 1812 retreat route.” The mass grave incorporates the stays of up to 3,000 troopers.
“Many soldiers arrived exhausted, starving and ill,” the microbiologist said.
“A substantial number died there and were interred rapidly in mass graves.”
“[The study] lets us put names to infections that symptom-based accounts alone cannot resolve.”
Rascovan said that hunger, numbing temperatures and typhus had been long identified as major causes of death, but that the research conclusively proves that paratyphoid fever and louse-borne relapsing fever had been also current.

These “may have contributed to debilitation and mortality,” Rascovan added.
Four of the 13 troopers examined optimistic for the paratyphoid fever bacterium, while two others examined optimistic for the relapsing fever bacterium.
Both bacterial infections trigger fever, headache and weak spot, and can unfold rapidly in crowded, unsanitary circumstances.

Rascovan emphasised that finding out historical DNA “lets us put names to infections that symptom-based accounts alone cannot resolve.”
“The co-occurrence of pathogens with different transmission routes underscores how dire sanitary conditions were,” he said.
“Future work across more sites and individuals will refine the disease landscape of 1812.”
