Detailed research that correlates life histories of symbiotic
spirochetes to changes in the immune system of associated vertebrates is sorely needed. Genome analyses show that in necrotrophic symbioses (Borrelia and Treponema sp.) of humans and other primates, integration of the bionts occurs at the gene product and genetic level.
Fascinating paper, Sojourner. Do post it on the antibiotic or general thread. I know many will enjoy reading.
Kitty- Sojourner has been here longer than you or I. And what this paper says is that our relationship to spirochetes have changed our genetics. More in line with Bob's hygiene hypothesis. Nine months of antibiotics will not change the human genome back.
