Most mammals, including humans, can serve as intermediate hosts. This pathogen, with its zoonotic potential, causes toxoplasmosis, a condition that can range from subclinical to fatal in humans. It is therefore important to assess the occurrence of the pathogen, even if only indirectly through the detection of antibodies. Epidemiological data on the seroprevalence in wild animals, including invasive species, are rare in Poland. Therefore, we tested 197 wild raccoons (Procyon lotor) and 89 raccoon dogs (Nyctereutes procyonoides) from Zgorzelec County, southwestern Poland, for the presence of antibodies. Samples were collected between January 2019 and December 2020 and analysed using a commercial indirect modified agglutination test (MAT, cut-off 1:25). The statistical analysis revealed significant differences in seroprevalence between the two predatory species. Of the 197 surveyed raccoons, 96 (48.73%; 95% confidence interval (CI): 41.73\u201355.73%) tested positive, while 25 of the 89 raccoon dogs (28.09%; 95% CI: 18.70\u201337.48%) were positive. Regarding risk factors, body weight and sex influenced the presence of T. gondii antibodies in both the species, with a higher likelihood of seropositivity among heavier animals and females, respectively. For raccoon dogs, juveniles were more likely to be seropositive than adults at a given weight. Our results suggest that T. gondii infection is widespread in the regional raccoon and raccoon dog populations, indicating a high level of parasite circulation in the environment.<\/jats:p>","DOI":"10.3390\/pathogens13030210","type":"journal-article","created":{"date-parts":[[2024,2,28]],"date-time":"2024-02-28T03:37:57Z","timestamp":1709091477000},"page":"210","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Prevalence of Toxoplasma gondii Antibodies and Risk Factors in Two Sympatric Invasive Carnivores (Procyon lotor and Nyctereutes procyonoides) from Zgorzelec County, Poland"],"prefix":"10.3390","volume":"13","author":[{"given":"Natalia","family":"Osten-Sacken","sequence":"first","affiliation":[{"name":"Centre for Veterinary Sciences, Nicolaus Copernicus University, 87-100 Toru\u0144, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3502-4240","authenticated-orcid":false,"given":"Jutta","family":"Pikalo","sequence":"additional","affiliation":[{"name":"Institute of Parasitology, University of Veterinary Medicine Vienna, Veterin\u00e4rplatz 1, 1210 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Steinbach","sequence":"additional","affiliation":[{"name":"Department of Zoology, Mus\u00e9e National d\u2019Histoire Naturelle, 2160 Luxembourg, Luxembourg"},{"name":"Faculty of Chemistry, Georg-August University of G\u00f6ttingen, 37073 G\u00f6ttingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4536-5508","authenticated-orcid":false,"given":"Mike","family":"Heddergott","sequence":"additional","affiliation":[{"name":"Department of Zoology, Mus\u00e9e National d\u2019Histoire Naturelle, 2160 Luxembourg, Luxembourg"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Dubey, J.P.
