Nodular lesions (granulomas) containing <jats:italic>Oesophagostomum<\/jats:italic> are commonly seen in the abdomen of infected chimpanzees post\u2010mortem. At Ta\u00ef National Park, C\u00f4te d'Ivoire, previous studies have identified larvae of a variety of <jats:italic>Oesophagostomum<\/jats:italic> spp. in wild chimpanzee stool, based on sequencing of larval DNA, and nodular lesions associated with <jats:italic>Oesophagostomum<\/jats:italic>, identified morphologically to the genus level but not sequenced. Here we present three recent cases of parasitic granulomas found post\u2010mortem in chimpanzees at Ta\u00ef. We complement descriptions of gross pathology, histopathology and parasitology with PCR and sequencing of DNA isolated from the parasitic nodules and from adult worms found inside the nodules. In all three cases, we identify <jats:italic>Oesophagostomum stephanostomum<\/jats:italic> as the causative agent. The sequences from this study were identical to the only other published sequences from nodules in nonhuman primates\u2014those from the wild chimpanzees of Gombe, Tanzania.<\/jats:p>","DOI":"10.1002\/ajp.23652","type":"journal-article","created":{"date-parts":[[2024,5,29]],"date-time":"2024-05-29T03:38:40Z","timestamp":1716953920000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["<i>Oesophagostomum stephanostomum<\/i> causing parasitic granulomas in wild chimpanzees (<i>Pan troglodytes verus<\/i>) of Ta\u00ef National Park, C\u00f4te d'Ivoire"],"prefix":"10.1002","volume":"86","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6157-337X","authenticated-orcid":false,"given":"Jenny E.","family":"Jaffe","sequence":"first","affiliation":[{"name":"Ta\u00ef Chimpanzee Project Centre Suisse de Recherches Scientifiques Abidjan C\u00f4te d'Ivoire"},{"name":"Epidemiology of Highly Infectious Pathogens Robert Koch Institute Berlin Germany"},{"name":"Department of Veterinary Medicine Freie Universit\u00e4t Berlin Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sonja","family":"Metzger","sequence":"additional","affiliation":[{"name":"Ta\u00ef Chimpanzee Project Centre Suisse de Recherches Scientifiques Abidjan C\u00f4te d'Ivoire"},{"name":"Epidemiology of Highly Infectious Pathogens Robert Koch Institute Berlin Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kerstin","family":"M\u00e4tz\u2010Rensing","sequence":"additional","affiliation":[{"name":"German Primate Center Leibniz Institute for Primate Research  G\u00f6ttingen Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1256-3316","authenticated-orcid":false,"given":"Alexis","family":"Ribas","sequence":"additional","affiliation":[{"name":"Parasitology Section, Department of Biology, Healthcare and Environment, Faculty of Pharmacy and Food Science; Institut de Recerca de la Biodiversitat (IRBio) University of Barcelona Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6490-4031","authenticated-orcid":false,"given":"Roman M.","family":"Wittig","sequence":"additional","affiliation":[{"name":"Ta\u00ef Chimpanzee Project Centre Suisse de Recherches Scientifiques Abidjan C\u00f4te d'Ivoire"},{"name":"Ape Social Mind Lab Institute of Cognitive Sciences Marc Jeannerod Bron France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2169-7375","authenticated-orcid":false,"given":"Fabian H.","family":"Leendertz","sequence":"additional","affiliation":[{"name":"Epidemiology of Highly Infectious Pathogens Robert Koch Institute Berlin Germany"},{"name":"Helmholtz Institute for One Health Greifswald Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,5,28]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0022149X00012840"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/1755-0998.12108"},{"key":"e_1_2_11_4_1","unstructured":"CDC.
