Neuroangiostrongyliasis is a globally emerging public health concern with several reported outbreaks; however, it remains neglected in the Philippines, where a lack of information on this parasite leads to underreporting and misdiagnosis. A good understanding of parasite epidemiology underpinned by accurate diagnosis is essential for treatment and control of parasitic diseases. Thus, this study aimed to determine the prevalence of <jats:italic>Angiostrongylus<\/jats:italic> spp. in rats in selected communities on Mindanao and Luzon Islands in the Philippines and provide accurate identification using molecular techniques.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods<\/jats:title>\n            <jats:p>A total of 126 rats were collected from selected communities in Laguna, Davao del Sur, Agusan del Sur, and Surigao del Norte. Lungs were harvested after dissection and artificially digested to isolate the parasite. DNA was extracted from the parasite, and SSU-rRNA and COI genes were amplified and sequenced.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>Results showed an <jats:italic>Angiostrongylus<\/jats:italic> spp. prevalence of 37.3% in rats with significantly higher prevalence in rural and sub-urban communities. Molecular analysis revealed two species: <jats:italic>Angiostrongylus cantonensis<\/jats:italic> and <jats:italic>A. malaysiensis<\/jats:italic>. This represents the first report of co-endemic <jats:italic>Angiostrongylus<\/jats:italic> spp. in Agusan del Sur, Mindanao.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>Our study revealed a high prevalence of <jats:italic>Angiostrongylus<\/jats:italic> spp. among rats from selected communities in the Philippines and identified new endemic sites, showing that the distribution of the parasite is wider than previously appreciated. Furthermore, two species were identified, which provides evidence of diverse <jats:italic>Angiostrongylus<\/jats:italic> species in the country. However, further studies are needed to investigate the pathogenicity of <jats:italic>A. malaysiensis<\/jats:italic>. Evidence of <jats:italic>Angiostrongylus<\/jats:italic> spp. in rats and the habit of eating raw or improperly prepared food in the surveyed communities may imply unseen transmission of <jats:italic>Angiostrongylus<\/jats:italic> spp. to humans. This highlights the need to establish the public health importance of angiostrongyliasis in the country starting with a surveillance scheme for this parasite.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Graphical abstract<\/jats:title>\n          <\/jats:sec>","DOI":"10.1186\/s13071-025-06989-4","type":"journal-article","created":{"date-parts":[[2025,10,14]],"date-time":"2025-10-14T12:42:19Z","timestamp":1760445739000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Evidence of new endemic foci of the foodborne helminths Angiostrongylus spp. in rats in selected communities in the Philippines"],"prefix":"10.1186","volume":"18","author":[{"given":"Allen Jethro I.","family":"Alonte","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martha E.","family":"Betson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Billy P.","family":"Divina","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vachel Gay V.","family":"Paller","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2025,10,14]]},"reference":[{"key":"6989_CR1","doi-asserted-by":"publisher","first-page":"2102","DOI":"10.1021\/acschemneuro.7b00335","volume":"8","author":"RH Cowie","year":"2017","unstructured":"Cowie RH.
