In olive baboons (<jats:italic>Papio anubis<\/jats:italic>) at Lake Manyara National Park, Tanzania, genital skin ulcers, caused by the bacterium <jats:italic>Treponema pallidum<\/jats:italic> subsp. <jats:italic>pertenue<\/jats:italic>, are associated with increased female mating avoidance and altered male mating patterns at a pre-copulatory and copulatory level. Beyond this, mating is also comprised of post-copulatory interactions among sexual partners (i.e., copulation calls, darting [post-copulatory sprint away from the male], and post-copulatory grooming). In baboons, female post-copulatory behavior is hypothesized to incite male-male competition, promote subsequent copulations, and\/or strengthen the bonds between the mating pairs. Due to a higher reproductive burden (i.e. pregnancy, lactation, infant rearing), females should avoid proceptive behavior after mating to decrease further exposure to potential pathogens. To investigate whether the presence of genital skin ulcers has an impact at the post-copulatory level, we analyzed 517 copulation events of 33 cycling females and 29 males with and without genital skin ulcers. The occurrence of female post-copulatory behaviors was not altered by genital skin ulcerations in males. Similar to other baboon populations, females in our study group were more likely to utter copulation calls after an ejaculatory copulation. The likelihood of darting was higher after ejaculatory copulations and with the presence of copulation calls. Post-copulatory grooming (i.e., occurring within 15 seconds after a copulation) was not frequently observed. Our results indicate that despite the presence of conspicuous signs of disease, female post-copulatory behavior was not affected by the genital health status of the males. This indicates that in our study group, infection cues caused by <jats:italic>T<\/jats:italic>. <jats:italic>pallidum<\/jats:italic> subsp. <jats:italic>pertenue<\/jats:italic> play a major role before and during mating, but not after mating. The post-copulatory behavior of females is most likely affected by physiological or evolutionary constraints other than sexually transmitted infections.<\/jats:p>","DOI":"10.1371\/journal.pone.0261894","type":"journal-article","created":{"date-parts":[[2022,1,20]],"date-time":"2022-01-20T18:36:17Z","timestamp":1642703777000},"page":"e0261894","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":4,"title":["Female post-copulatory behavior in a group of olive baboons (Papio anubis) infected by Treponema pallidum"],"prefix":"10.1371","volume":"17","author":[{"given":"Filipa M.
