This study investigates the relative impact of encounter rates on <jats:italic>A. cantonensis<\/jats:italic> prevalence in snail hosts by assessing their coprophagic tendencies. Multiple-choice feeding assays were conducted with four snail species (<jats:italic>Parmarion martensi<\/jats:italic>, <jats:italic>Laevicaulis alte<\/jats:italic>, <jats:italic>Lissachatina fulica<\/jats:italic>, and <jats:italic>Veronicella cubensis<\/jats:italic>) differing in <jats:italic>A<\/jats:italic>. <jats:italic>cantonensis<\/jats:italic> prevalence. The snails were offered romaine lettuce, hibiscus flowers, papaya, and rat feces. The relative intake ratios (RIR) were calculated and used to evaluate 1) feces preference among the snail species, and 2) correlation between feces preference and <jats:italic>A. cantonensis<\/jats:italic> prevalence. We also compared preferences for feces from rats fed high-fat and balanced diets; no significant difference was observed. Feces made up the highest proportion of the diet of <jats:italic>P. martensi<\/jats:italic> (11.6%), followed by <jats:italic>V. cubensis<\/jats:italic> (7.8%), <jats:italic>L. fulica<\/jats:italic> (5.9%), and <jats:italic>L. alte<\/jats:italic> (5.1%). Additionally, <jats:italic>P. martensi<\/jats:italic> showed a significantly higher preference (RIR) than all other species. The correlation between feces preference and <jats:italic>A. cantonensis<\/jats:italic> prevalence among species was weakly positive. These findings suggest that the level of coprophagy influences encounter rates with <jats:italic>A. cantonensis<\/jats:italic>, contributing to variation in infection prevalence among snail species. However, other factors may also play a role, as preference and prevalence were only weakly correlated. Understanding these dynamics can inform strategies for managing the spread of <jats:italic>A. cantonensis<\/jats:italic> and mitigating its health impacts.<\/jats:p>","DOI":"10.1051\/parasite\/2024075","type":"journal-article","created":{"date-parts":[[2024,12,23]],"date-time":"2024-12-23T08:45:46Z","timestamp":1734943546000},"page":"76","source":"Crossref","is-referenced-by-count":2,"title":["Snail coprophagy: the encounter filter, food preferences, and rat lungworm (<i>Angiostrongylus cantonensis<\/i>) prevalence"],"prefix":"10.1051","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3768-4499","authenticated-orcid":false,"given":"Randi L.","family":"Rollins","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0380-4023","authenticated-orcid":false,"given":"Chasen D.","family":"Griffin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2986-7092","authenticated-orcid":false,"given":"Robert H.","family":"Cowie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"250","published-online":{"date-parts":[[2024,12,23]]},"reference":[{"key":"R1","doi-asserted-by":"crossref","first-page":"150893","DOI":"10.1016\/j.pedobi.2023.150893","volume":"99\u2013100","author":"Ampuero","year":"2023","journal-title":"Pedobiologia"},{"key":"R2","first-page":"184","volume":"57","author":"Asato","year":"2004","journal-title":"Japanese Journal of Infectious Diseases"},{"key":"R3","first-page":"163","volume":"24","author":"Ash","year":"1976","journal-title":"Revista de Biolog\u00eda Tropical"},{"key":"R4","doi-asserted-by":"crossref","first-page":"1087","DOI":"10.1017\/S0031182016000652","volume":"143","author":"Barratt","year":"2016","journal-title":"Parasitology"},{"key":"R5","doi-asserted-by":"crossref","first-page":"616","DOI":"10.1016\/j.pt.2020.04.010","volume":"36","author":"Bernardo-Cravo","year":"2020","journal-title":"Trends in Parasitology"},{"key":"R6","doi-asserted-by":"crossref","first-page":"2625","DOI":"10.1038\/s41396-020-0711-6","volume":"14","author":"Bo","year":"2020","journal-title":"ISME Journal"},{"key":"R7","doi-asserted-by":"crossref","first-page":"e75962","DOI":"10.1371\/journal.pone.0075962","volume":"8","author":"Boyer","year":"2013","journal-title":"PLoS One"},{"key":"R8","doi-asserted-by":"crossref","first-page":"427","DOI":"10.1111\/brv.12009","volume":"88","author":"Brearley","year":"2013","journal-title":"Biological Reviews of the Cambridge Philosophical Society"},{"key":"R9","unstructured":"Cameron R. 2016.
