Frogs can be hosts for several parasites that negatively affect their development and health. The objective of this study was to identify the presence of intestinal parasites in bullfrogs in aquaculture production units. Eighteen bullfrogs aquaculture production units were selected, and 20 animals (n=360) from each farm. Fecal samples were obtained by mucosal scraping and processed using the concentration method. The overall prevalence of intestinal parasites was 70.5%, and all farms had frogs infected by some species of parasite. Two species of parasites were identified: Eimeria sp. and Strongyloides sp. Significant differences were found regarding parasite prevalence between males and females (73.8% vs 58.8%) and regarding tibia length (5.5 vs 6.1 cm) and weight (168 vs 187 g) between parasitized and non-parasitized frogs. In conclusion, the present study showed a high prevalence of intestinal parasites, and morphometric alterations (weight, snout-cloaca length, radio-ulna length, tibia length and distance between parotid glands) were identified in the parasitized animals. These results provided useful information that will enable establishment of adequate control measures to help minimize the adverse effects of these parasites.<\/jats:p>","DOI":"10.1590\/s1984-29612023038","type":"journal-article","created":{"date-parts":[[2023,6,30]],"date-time":"2023-06-30T11:37:24Z","timestamp":1688125044000},"source":"Crossref","is-referenced-by-count":3,"title":["Gastrointestinal parasites in bullfrogs (Lithobates catesbeianus) in aquaculture production units in the Mexican central highlands"],"prefix":"10.1590","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8261-5129","authenticated-orcid":false,"given":"Emmanuel","family":"Hern\u00e1ndez-Valdivia","sequence":"first","affiliation":[{"name":"Universidad Aut\u00f3noma de Aguascalientes, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7511-3099","authenticated-orcid":false,"given":"Efra\u00edn","family":"Islas-Ojeda","sequence":"additional","affiliation":[{"name":"Universidad Aut\u00f3noma de Aguascalientes, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0069-6450","authenticated-orcid":false,"given":"Rafael","family":"Casillas-Pe\u00f1uelas","sequence":"additional","affiliation":[{"name":"Universidad Aut\u00f3noma de Aguascalientes, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9354-0588","authenticated-orcid":false,"given":"Arturo","family":"Valdivia-Flores","sequence":"additional","affiliation":[{"name":"Universidad Aut\u00f3noma de Aguascalientes, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5450-3197","authenticated-orcid":false,"given":"Alberto","family":"Garc\u00eda-Mungu\u00eda","sequence":"additional","affiliation":[{"name":"Universidad Aut\u00f3noma de Aguascalientes, Mexico"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","published-online":{"date-parts":[[2023]]},"reference":[{"issue":"3","key":"ref1","doi-asserted-by":"crossref","first-page":"1057","DOI":"10.1007\/s00436-019-06548-8","article-title":"First database of the spatial distribution of Eimeria species of cattle, sheep and goats in Mexico","volume":"119","author":"Alcala-Canto Y","year":"2020","journal-title":"Parasitol Res"},{"key":"ref2","series-title":"Keys to the nematode parasites of vertebrates: archival volume.","author":"Anderson RC","year":"2009"},{"issue":"1","key":"ref3","doi-asserted-by":"crossref","first-page":"75","DOI":"10.24039\/rnh201261998","article-title":"Longibucca catesbeianae (Nematoda: Cylindrocorporidae) en la Rana-Toro.
