Did Christopher Columbus and his men introduce syphilis into Renaissance Europe, after contracting it during their voyage to the New World? Or does this pathogen have a much older history? A study by Kristin Harper and colleagues published last week in PLoS Neglected Tropical Diseases lends support to what’s known as the Columbian theory of syphilis’s origin while suggesting that the non-sexually-transmitted subspecies arose earlier in the Old World.

The study spread throughout both mainstream press and science blogosphere alike, as did a related Expert Commentary, written by Connie Mulligan and colleagues, that challenged the methods and findings of the syphilis study.

Bora made sure that “syphilis” was the buzzword of the day on ScienceBlogs, and three of his SciBlings’ amazing blogs are highlighted here:

Aetiology: Where did syphilis come from?
Afarensis: Syphils: The View from Bioarchaeology
Greg Laden: The Origin of Syphilis

Jonathan Eisen also blogged about the paper, and drew our attention to a CBC Radio interview with one of the study’s co-authors that you can listen to here.

Carl Zimmer wrote about the paper in Science, and mentions it on his blog.

The study was picked up by more than 100 outlets total. Some of the excellent coverage is highlighted here:
