Phylogeny of leprosy, relevant for prehistoric Eurasian contacts

leprosy-medieval-europe

Some interesting studies were published at roughly the same time as Damgaard et al. (Nature 2018 and Science 2018), and that’s probably why they got little attention (at least by me).

Monica H. Green (also in Academia.edu), specialized in History of Medicine, summed up their relevance in Twitter quite well (her text is edited here for clarity):

I’ve been disappointed that three recent exceptional studies of one of the world’s most historically important diseases, leprosy, have gotten so little notice from the science communication. It will take me a few hours to lay out their significance. But

Open access Ancient DNA study reveals HLA susceptibility locus for leprosy in medieval Europeans, by Krause-Kyora et al., Nature Communications (2018)

Abstract:

Leprosy, a chronic infectious disease caused by Mycobacterium leprae (M. leprae), was very common in Europe till the 16th century. Here, we perform an ancient DNA study on medieval skeletons from Denmark that show lesions specific for lepromatous leprosy (LL). First, we test the remains for M. leprae DNA to confirm the infection status of the individuals and to assess the bacterial diversity. We assemble 10 complete M. leprae genomes that all differ from each other. Second,
