The aim of this study was to evaluate the prevalence of anti-T. gondii and anti-N. caninum antibodies and the factors associated with infections in beef cattle intended for human consumption in an Amazonian area of North Brazil. We collected blood samples of 387 cattle from 50 herds located in different municipalities of the State of Rond\u00f4nia. An epidemiological questionnaire was distributed to farmers, with regard to nutritional, sanitary and reproductive herd management. The samples were identified, refrigerated and sent for serological analyses via IFAT (Immunofluorescent Antibody Test). Among the 387 analyzed animals, 91 (23.5%; CI 95%: 18.8\u201327.2) were positive for anti-T. gondii antibodies, with titers varying from 1:64 (75.8%) to 1:512 (2.2%). For anti-N. caninum antibodies, only four animals (1%; CI 95%: 0\u20132.7) were positive, with titers ranging from 1:400 (50%) to 1:1600 (25%). We observed a significant rate of anti-T. gondii antibodies in the variables \u201cpure breed\u201d and \u201ccontact with free-range chickens\u201d (p &lt; 0.2). There were no risk factors associated with the presence of anti-T. gondii or anti-N. caninum antibodies. In conclusion, there was a high prevalence of anti-T. gondii antibodies in beef cattle intended for human consumption in the State of Rond\u00f4nia, Brazil, and a low prevalence of anti-N. caninum antibodies. Longitudinal studies can better elucidate the cause of these prevalence levels and how they could be better prevented and controlled.<\/jats:p>","DOI":"10.3390\/tropicalmed8070359","type":"journal-article","created":{"date-parts":[[2023,7,11]],"date-time":"2023-07-11T01:42:58Z","timestamp":1689039778000},"page":"359","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Seropositivity of Anti-Toxoplasma gondii and Anti-Neospora caninum Antibodies in Cattle Intended for Human Consumption in an Amazonian Area of North Brazil"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-8985-8072","authenticated-orcid":false,"given":"Victor Hugo Alves","family":"Sousa Formiga","sequence":"first","affiliation":[{"name":"Department of Veterinary Medicine, Instituto Federal da Para\u00edba\u2014IFPB, Sousa 58807-630, Para\u00edba, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Felipe Boniedj Ventura","family":"Alvares","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, Instituto Federal da Para\u00edba\u2014IFPB, Sousa 58807-630, Para\u00edba, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mariana Moreira","family":"Anjos","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, Universidade Federal de Rond\u00f4nia\u2014UNIR, Rolim de Moura 76940-000, Rond\u00f4nia, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jefferson Vieira","family":"Freitas","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, Universidade Federal de Rond\u00f4nia\u2014UNIR, Rolim de Moura 76940-000, Rond\u00f4nia, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daiane Peixer","family":"Silva","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, Universidade Federal de Rond\u00f4nia\u2014UNIR, Rolim de Moura 76940-000, Rond\u00f4nia, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roberta Nunes","family":"Parentoni","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, Universidade Federal da Para\u00edba, Jo\u00e3o Pessoa 58059-900, Para\u00edba, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arthur Willian","family":"Lima Brasil","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, Universidade Federal da Para\u00edba, Jo\u00e3o Pessoa 58059-900, Para\u00edba, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gl\u00e1ucia Dioj\u00e2nia Azev\u00eado","family":"Medeiros","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, Instituto Federal da Para\u00edba\u2014IFPB, Sousa 58807-630, Para\u00edba, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thais Ferreira","family":"Feitosa","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, Instituto Federal da Para\u00edba\u2014IFPB, Sousa 58807-630, Para\u00edba, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9891-7842","authenticated-orcid":false,"given":"Vin\u00edcius Longo Ribeiro","family":"Vilela","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, Instituto Federal da Para\u00edba\u2014IFPB, Sousa 58807-630, Para\u00edba, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,10]]},"reference":[{"key":"ref_1","unstructured":"ABIEC (2023, May 07).
