The capybara (<jats:italic>Hydrochoerus hydrochaeris<\/jats:italic>) is the largest living rodent in the world, and its distribution is associated with the presence of tropical and subtropical wetlands in South America. The Los Padres Lake Integral Reserve (LPLIR) is an important conservation zone in the pampean region of Argentina. One of the emblematic species found within the reserve is the capybara. The objective of this study was to determine the gastrointestinal parasites present in wild capybaras of the LPLIR and to compare different coprological methodologies. Free-ranging capybara fresh feces from 57 individuals were randomly collected from the area of LPLIR in the summer of 2022. Three different techniques were applied: spontaneous sedimentation technique (SS), INTA modified McMaster technique (MM), and Mini-FLOTAC (MF) technique. Fifty-six samples from all samples analysed (56\/57, 98%) were found to be positive for gastrointestinal parasites. Two species of Strongylida,<jats:italic>Protozoophaga obesa<\/jats:italic>,<jats:italic>Echinocoleus hydrochaeris<\/jats:italic>, one unidentified nematode, one unidentified spirurid, and at least two morphotypes of<jats:italic>Eimeria<\/jats:italic>spp. oocysts were recorded. There were found significant differences in the proportion of positive samples and in richness by technique, but no significant differences were found in parasite counting. In conclusion, the choice of methodology depends on the specific objectives of the study. This is the first parasitological study of capybaras from the LPLIR and represents an exploration of parasite communities present in these wild rodents at their southernmost distribution.<\/jats:p>","DOI":"10.1017\/s0022149x23000767","type":"journal-article","created":{"date-parts":[[2023,12,13]],"date-time":"2023-12-13T11:06:18Z","timestamp":1702465578000},"source":"Crossref","is-referenced-by-count":1,"title":["Gastrointestinal parasite assemblages from the wild rodent capybara (<i>Hydrochoerus hydrochaeris<\/i>) inhabiting a natural protected area from Argentina"],"prefix":"10.1017","volume":"97","author":[{"given":"E.","family":"Tietze","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Bellusci","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"V.","family":"Ca\u00f1al","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.","family":"Cringoli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7665-8576","authenticated-orcid":false,"given":"M.O.","family":"Beltrame","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2023,12,13]]},"reference":[{"key":"S0022149X23000767_r4","doi-asserted-by":"crossref","first-page":"e0221662","DOI":"10.1371\/journal.pone.0221662","article-title":"A morphological, molecular and life cycle study of the capybara parasite Hippocrepis hippocrepis (Trematoda: Notocotylidae)","volume":"14","author":"Assis","year":"2019","journal-title":"PLoS ONE"},{"key":"S0022149X23000767_r39","first-page":"199","article-title":"Estructura y din\u00e1mica de la comunidad perif\u00edtica sobre Ricciocarpus natans (Hepaticae) de la Laguna de Los Padres (Buenos Aires, Argentina)","volume":"30","author":"Pozzobon","year":"1995","journal-title":"Bolet\u00edn de la Sociedad Argentina de Bot\u00e1nica"},{"key":"S0022149X23000767_r22","doi-asserted-by":"crossref","first-page":"439","DOI":"10.1007\/s00705-016-3121-3","article-title":"Molecular evidence of Orthopoxvirus DNA in capybara (Hydrochoerus hydrochaeris) stool samples","volume":"162","author":"Dutra","year":"2017","journal-title":"Archives of Virology"},{"key":"S0022149X23000767_r17","doi-asserted-by":"crossref","first-page":"19","DOI":"10.1644\/12-MAMM-A-030.1","article-title":"Influence of group sizes and food resources in home-range sizes of capybaras from Argentina","volume":"94","author":"Corriale","year":"2013","journal-title":"Journal of Mammalogy"},{"key":"S0022149X23000767_r36","volume-title":"Estudio biol\u00f3gico del chig\u00fcire o capibara","author":"Ojasti","year":"1973"},{"key":"S0022149X23000767_r32","doi-asserted-by":"crossref","first-page":"908486","DOI":"10.3389\/fvets.2022.908486","article-title":"A comparative study of Mini-FLOTAC with traditional coprological techniques in the analysis of cetacean fecal samples","volume":"9","author":"Marcer","year":"2022","journal-title":"Frontiers in Veterinary Science"},{"key":"S0022149X23000767_r27","first-page":"171","volume-title":"The epidemiology, diagnosis and control of helminth parasites of ruminants.
