In this study, 1281 wild boar kidney samples collected in the federal state of Saxony-Anhalt were analyzed by real-time PCR to investigate the presence of pathogenic and intermediate Leptospira DNA. Pathogenic Leptospira DNA was detected in 3.1% (95% CI = 2.3\u20134.2) of the samples, whereas intermediate Leptospira DNA was identified in 0.6% (95% CI = 0.3\u20131.2). Pathogenic Leptospira showed a widespread distribution across the study area, with a significantly higher prevalence in the district of Salzlandkreis (p = 0.04, OR = 3.4, CI = 0.8\u201310.3). Evaluation of host-related and environmental factors revealed a significant association between pathogenic Leptospira DNA detection and both sub-adult age class (\u03c72 = 13.1, df = 2, p = 0.0014) and autumn season (\u03c72 = 12.3, df = 3, p = 0.0066), whereas no significant association was observed for sex. Neither of these factors showed a significant relation with intermediate Leptospira spp. Sequence analyses of rrs and 16S rRNA genes predominantly identified as L. interrogans (62.5%), followed by L. borgpetersenii (20.0%) and L. kirschneri (5.0%). All intermediate Leptospira sequences were identified as L. fainei. Notably, this study provides the first molecular evidence of intermediate L. fainei DNA in wild boar kidneys in Germany. Overall, these findings suggest that wild boar may act as renal carriers of Leptospira spp. and support their potential relevance in the epidemiology of leptospirosis within wildlife populations in Saxony-Anhalt.<\/jats:p>","DOI":"10.3390\/ani16071025","type":"journal-article","created":{"date-parts":[[2026,3,27]],"date-time":"2026-03-27T11:32:47Z","timestamp":1774611167000},"page":"1025","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Wild Boar (Sus scrofa) as Reservoir of Pathogenic and Intermediate Leptospira"],"prefix":"10.3390","volume":"16","author":[{"given":"Alice","family":"Stagnoli","sequence":"first","affiliation":[{"name":"Department of Veterinary Medicine, State Office for Consumer Protection Saxony-Anhalt, 39576 Stendal, Germany"},{"name":"Centre of Veterinary Public Health, Institute of Animal Hygiene and Veterinary Public Health, University of Leipzig, 04103 Leipzig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert Valerio","family":"House","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, State Office for Consumer Protection Saxony-Anhalt, 39576 Stendal, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karen","family":"Dohmann","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, State Office for Consumer Protection Saxony-Anhalt, 39576 Stendal, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomke Friederike","family":"Pr\u00fcser","sequence":"additional","affiliation":[{"name":"Department of Food Safety, State Office for Consumer Protection Saxony-Anhalt, 06112 Halle (Saale), Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anne-Catrin","family":"Geuthner","sequence":"additional","affiliation":[{"name":"Department of Food Safety, State Office for Consumer Protection Saxony-Anhalt, 06112 Halle (Saale), Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Catrin","family":"Albrecht","sequence":"additional","affiliation":[{"name":"Department of Veterinary Medicine, State Office for Consumer Protection Saxony-Anhalt, 39576 Stendal, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2457-8224","authenticated-orcid":false,"given":"Martin","family":"Pfeffer","sequence":"additional","affiliation":[{"name":"Centre of Veterinary Public Health, Institute of Animal Hygiene and Veterinary Public Health, University of Leipzig, 04103 Leipzig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Vincent, A.T., Schiettekatte, O., Goarant, C., Neela, V.K., Bernet, E., Thibeaux, R., Ismail, N., Mohd Khalid, M.K.N., Amran, F., and Masuzawa, T.
