The virus can infect sow herds through various routes. One possible risk factor is the transmission of PRRSV through artificial insemination with infected boar semen. For these reasons, conventional boar studs should be closely monitored to detect an outbreak of PRRSV at an early stage. In the presented retrospective study, 2184 fresh semen samples from 336 boars were investigated (RT-qPCR) after an accidental PRRSV introduction to the herd. Hence, the different shedding profiles of PRRSV via semen resulted in 42.2% where no virus was detected, 2.0% intermittent shedding, and 8.4% permanent shedding. The duration of viral shedding varies from 2 days to 83 days post outbreak (on average 33 days). A significant impact of breed on PRRSV shedding duration could not be shown. Also, the distribution of the shedding profile does not follow a consistent mode, indicating that not every boar is shedding the virus via semen.<\/jats:p>","DOI":"10.3390\/vetsci11110557","type":"journal-article","created":{"date-parts":[[2024,11,11]],"date-time":"2024-11-11T11:34:11Z","timestamp":1731324851000},"page":"557","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["An Outbreak of Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) in a German Boar Stud: A Retrospective Analysis of PRRSV Shedding in Boar Semen"],"prefix":"10.3390","volume":"11","author":[{"given":"Jakob","family":"Aundrup","sequence":"first","affiliation":[{"name":"Swine Health Service, LUFA Nord-West, Institute for Animal Health, Ammerl\u00e4nder Heerstra\u00dfe 123, D-26129 Oldenburg, Germany"},{"name":"Veterinary Practice Melle, Lammersbrink 8, D-49328 Melle, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caroline","family":"L\u00fcken","sequence":"additional","affiliation":[{"name":"LUFA Nord-West, Institute for Animal Health, Ammerl\u00e4nder Heerstra\u00dfe 123, D-26129 Oldenburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2330-5029","authenticated-orcid":false,"given":"Kristin","family":"Heenemann","sequence":"additional","affiliation":[{"name":"Centre for Infectious Diseases, Institute of Virology, Faculty of Veterinary Medicine, University of Leipzig, An den Tierkliniken 29, D-04103 Leipzig, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas W.","family":"Vahlenkamp","sequence":"additional","affiliation":[{"name":"Centre for Infectious Diseases, Institute of Virology, Faculty of Veterinary Medicine, University of Leipzig, An den Tierkliniken 29, D-04103 Leipzig, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3994-5979","authenticated-orcid":false,"given":"Isabel","family":"Hennig-Pauka","sequence":"additional","affiliation":[{"name":"Field Station for Epidemiology, University of Veterinary Medicine Hannover, Foundation, Buescheler Str. 9, D-49456 Vechta, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.virusres.2010.10.009","article-title":"Porcine reproductive and respiratory syndrome virus: An update on an emerging and re-emerging viral disease of swine","volume":"154","author":"Lunney","year":"2010","journal-title":"Virus Res."},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Zimmerman, J.J.
