T. gondii is a zoonotic pathogen for which cats are the definitive host, whereas N. caninum is a major cause of reproductive losses in cattle, with dogs acting as the definitive host. Data on exposure in pet animals in Thailand remain limited. This study investigated seroprevalence and associated risk factors of T. gondii and N. caninum in pet cats and dogs in Pathum Thani Province, an urban area adjacent to Bangkok. Between June 2020 and July 2021, serum samples were collected from 169 owned animals, including 86 cats and 83 dogs, participating in a mobile sterilization program. Antibodies were detected using the indirect fluorescent antibody test (IFAT), and animal characteristics, behaviors, and environmental factors were obtained via owner questionnaires. Serological evidence of exposure to both parasites was detected. Antibodies against T. gondii were detected in 4.73% (8\/169) of animals, including 4.65% (4\/86) of cats and 4.82% (4\/83) of dogs. For N. caninum, the overall seroprevalence was 10.06% (17\/169), with a higher prevalence in dogs (15.66%, 13\/83) than in cats (4.65%, 4\/86). No significant risk factors were identified for T. gondii or N. caninum infection in either cats or dogs (p &gt; 0.05).<\/jats:p>","DOI":"10.3390\/tropicalmed11040089","type":"journal-article","created":{"date-parts":[[2026,3,25]],"date-time":"2026-03-25T13:57:34Z","timestamp":1774447054000},"page":"89","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Occurrence of Toxoplasma gondii and Neospora caninum Antibodies in Pet Cats and Dogs in Pathum Thani, Thailand"],"prefix":"10.3390","volume":"11","author":[{"given":"Nhung Pho Nguyen","family":"Nguyen","sequence":"first","affiliation":[{"name":"Department of Parasitology, Faculty of Veterinary Medicine, Kasetsart University, Bangkok 10900, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thuy Thi","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, Faculty of Animal Science and Veterinary Medicine, College of Agriculture and Forestry, Hue University, Hue City 530000, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chonchadayu","family":"Phanpha","sequence":"additional","affiliation":[{"name":"Department of Parasitology, Faculty of Veterinary Medicine, Kasetsart University, Bangkok 10900, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ketsarin","family":"Kamyingkird","sequence":"additional","affiliation":[{"name":"Department of Parasitology, Faculty of Veterinary Medicine, Kasetsart University, Bangkok 10900, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adrian B.","family":"Hehl","sequence":"additional","affiliation":[{"name":"Laboratory of Molecular Parasitology, Institute of Parasitology, Vetsuisse and Medical Faculty, University of Zurich, CH-8057 Zurich, Switzerland"},{"name":"One Health Institute, Vetsuisse, Science, and Medical Faculties, University of Zurich, CH-8057 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5982-4811","authenticated-orcid":false,"given":"Tawin","family":"Inpankaew","sequence":"additional","affiliation":[{"name":"Department of Parasitology, Faculty of Veterinary Medicine, Kasetsart University, Bangkok 10900, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Martin, F., Bachert, K.E., Snow, L., Tu, H.-W., Belahbib, J., and Lyn, S.A.
