To determine the prevalence and risk factors associated with these parasites, a study was conducted on 595 sheep in C\u00f3rdoba, Colombia. Prevalence and parasite burden were determined using the McMaster technique. Larvae were cultured from feces to identify the nematode genera. For the analysis of associated factors and parasite burden, data means, medians, and confidence intervals were compared. A georeferenced data analysis was performed and an epidemiological map was constructed. An overall prevalence of 88.2% was found, with the highest prevalence and parasite burden for Strongylida (83.2%) and <jats:italic>Strongyloides<\/jats:italic> (41%) nematodes. The mean parasite burden was 1255 eggs per gram. The gastrointestinal nematode genera identified were <jats:italic>Trichostrongylus<\/jats:italic>, <jats:italic>Strongyloides<\/jats:italic>, <jats:italic>Haemonchus<\/jats:italic>, <jats:italic>Oesophagostomum<\/jats:italic>, <jats:italic>Bunostomum<\/jats:italic>, and <jats:italic>Cooperia<\/jats:italic>. In general, a significant association was found between parasite burden and dewormed animals, anthelmintic used, date of last deworming, and breeds. The FAMACHA\u00ae method and body condition showed a significant association with the Strongylida parasite burden. Clusters with higher intensity of gastrointestinal nematode burden and high prevalence were observed in the regions of Bajo Sin\u00fa, Sin\u00fa Medio, and San Jorge.<\/jats:p>","DOI":"10.1007\/s11250-022-03170-2","type":"journal-article","created":{"date-parts":[[2022,4,26]],"date-time":"2022-04-26T11:03:59Z","timestamp":1650971039000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Status of gastrointestinal nematode infections and associated epidemiological factors in sheep from C\u00f3rdoba, Colombia"],"prefix":"10.1007","volume":"54","author":[{"given":"Elisa Brunal","family":"Tachack","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teresa","family":"Oviedo-Socarr\u00e1s","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Misael Oviedo","family":"Pastrana","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0685-4667","authenticated-orcid":false,"given":"Luis Carlos","family":"P\u00e9rez-Cogollo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yonairo Herrera","family":"Benavides","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Clara Rugeles","family":"Pinto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oscar Vergara","family":"Garay","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,4,26]]},"reference":[{"key":"3170_CR1","doi-asserted-by":"publisher","first-page":"7765","DOI":"10.1038\/s41598-020-64775-x","volume":"10","author":"HM Aboshady","year":"2020","unstructured":"Aboshady, H.M., Stear, M.J., Johansson, A., Jonas, E, Bambou, J.C., 2020.
