Within a wk of inpatient hospitalization, Anti treponemal abs are checked and and come back positive with Negative RPR. Pt hadn’t had sex in yrs and doesn't’ remember ever getting penicillin injections. So this is presumed late latent syphilis. (2/3)

Ancient DNA from a 2,000-year-old burial site in Brazil rewrites the history of the family of microorganisms that causes syphilis and other ‘treponemal’ diseases. It could have mutated 10,000 years earlier than previously thought. www.nature.com/articles/d41...
Ancient DNA recovered from Brazilian remains shows that treponemal diseases originated some 10,000 years earlier than previously thought. Ancient DNA recovered from Brazilian remains shows that trepon...
Redefining the treponemal history through pre-Columbian genomes from Brazil
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 before the fifteenth century European contact with the Americas.
Hey it’s the wonderful fellow I’m married to, bringing us all exciting facts about the social history of responses to treponemal diseases! (I love him so much.)
