Given what day it is, I was about to start a mini-🧵 on this Nature study on the earliest documented treponema genomes (the organisms involved in syphilis & a couple of related diseases). But then I saw that the editors at Nature had posted a "notice of concern": www.nature.com/articles/s41... 🧪
Reconstruction of four Treponema pallidum genomes associated with human remains from around 2,000 years ago suggests that T. pallidum existed in the Americas and diverged to its modern subspecies befo...
It's a little more complicated than that. The oldest remains with definitive Treponema pallidum genomes present are from Brazil, 2000 years ago. There are also remains from the 12th century in Finland/Estonia with signs of a Treponema-like illness that may or may not have been syphilis.
Research on 2,000 year-old bones unearthed in Brazil is attempting to shed some light on the much debated origins of syphilis.
A sífilis é infecção causada por uma bactéria chamada Treponema pallidum, e mesmo que você tenha tido uma vez e feito o tratamento corretamente, você pode se reinfectar. Não gera imunidade.
Ich drücke die Daumen. Auf Treponema pallidum wurde nicht getestet? Nur um es safe auszuschließen? 🥺
3) A taxa de transmissão é alta 30% mas cai drasticamente após um ano. 4) A bactéria ‘Treponema pallidum’ não está resistente à penicilina. Continua bastante sensível.

On the origin of the #treponematosespubmed.ncbi.nlm.nih.gov/18235852/#syphilis in 1495, controversy has surrounded the origins of the bacterium Treponema pallidum subsp. pallidum
Our results lend support to the Columbian theory of syphilis's origin while suggesting that the non-sexually transmitted subspecies arose earlier in the Old World. This study represents the first atte...
