In Guatemala, no new data have been reported for the past 80 years on CE. To address this gap, a cross-sectional study at the municipal slaughterhouse of Quetzaltenango was conducted from March to August 2022 to determine the presence of <jats:italic>Echinococcus<\/jats:italic> sp. in backyard pigs. Moreover, the species and haplotypes, fertility status of hydatid cysts, association of fertility of the cysts to the sex of the pig and the size of cysts were investigated. For this purpose, 117 pigs were examined post-mortem, and cysts were extracted from their organs. Species identification was performed using nested polymerase chain reaction targeting the <jats:italic>cox1<\/jats:italic> gene, and a haplotype network was constructed. Generalized linear models (GLMs) were applied to assess correlation between cysts fertility, sex of the pig and diameter of the cyst. The study revealed a high prevalence of 38\u00b746% of CE, and a minimum prevalence of <jats:italic>Taenia hydatigena<\/jats:italic> of 4\u00b727%. Genetic characterization confirmed the presence of <jats:italic>Echinococcus canadensis<\/jats:italic> of the G7 haplogroup. Eight haplotypes unique to Guatemala were identified, along with one of global occurrence. Cysts from male pigs were 3\u00b76 times more likely to be fertile than those from female pigs. A quadratic GLM determined that cysts with a diameter range of 2\u00b709\u20134\u00b720 cm had a higher probability of being fertile. The high prevalence of CE and the diversity of Guatemalan haplotypes confirm the endemicity of <jats:italic>E. canadensis<\/jats:italic> in this region.<\/jats:p>","DOI":"10.1017\/s0031182025000150","type":"journal-article","created":{"date-parts":[[2025,2,14]],"date-time":"2025-02-14T08:21:12Z","timestamp":1739521272000},"page":"205-216","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":2,"title":["First report of <i>Echinococcus canadensis<\/i> (G7) in backyard pigs from the western highlands of Guatemala"],"prefix":"10.1017","volume":"152","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1045-0497","authenticated-orcid":false,"given":"Roderico","family":"Hern\u00e1ndez-Chea","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Am\u00e9rico Yoel","family":"Arag\u00f3n-M\u00e9ndez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-4228-7421","authenticated-orcid":false,"given":"Alejandro","family":"Hun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paola","family":"Morales-Ram\u00edrez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilde","family":"Silva","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1487-6797","authenticated-orcid":false,"given":"Federico","family":"Villatoro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6622-9997","authenticated-orcid":false,"given":"Marion","family":"Wassermann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2025,2,14]]},"container-title":["Parasitology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0031182025000150","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,5,19]],"date-time":"2025-05-19T09:37:41Z","timestamp":1747647461000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0031182025000150\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,2]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2025,2]]}},"alternative-id":["S0031182025000150"],"URL":"https:\/\/doi.org\/10.1017\/s0031182025000150","relation":{},"ISSN":["0031-1820","1469-8161"],"issn-type":[{"value":"0031-1820","type":"print"},{"value":"1469-8161","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,2]]},"assertion":[{"value":"\u00a9 The Author(s), 2025.
