At parturition, 3 newborn piglets from each litter were randomly selected and euthanatized prior to suckling. Samples of the mesenteric lymph nodes, spleens, kidneys, hearts and lungs were collected for PCR, histopathological and immunohistochemical assays. The results showed that the newborn piglets from PCV2b-infected sows had histopathological lesions in the tested tissues. Moreover, PCV2b antigen and DNA were detected as well. These findings therefore suggested that porcine circovirus type 2b can be transmitted across the placenta of sows, thereby leading to PCV2b vertical infection of the fetuses.<\/jats:p>","DOI":"10.1515\/pjvs-2016-0059","type":"journal-article","created":{"date-parts":[[2016,10,19]],"date-time":"2016-10-19T10:02:47Z","timestamp":1476871367000},"page":"471-476","source":"Crossref","is-referenced-by-count":4,"title":["Vertical Transmission of PCV2b to Fetuses in Sows Intramuscularly Infected with PCV2b"],"prefix":"10.1515","volume":"19","author":[{"given":"Wang Nai","family":"Dong","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li Jing","family":"Jun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wang Ai","family":"Bing","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhu","family":"Zhe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chang","family":"Yan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mao","family":"Yu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zan","family":"Yang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wang Zan","family":"Feng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deng Zhi","family":"Bang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","reference":[{"key":"ref181","doi-asserted-by":"crossref","first-page":"541","DOI":"10.1128\/JVI.76.2.541-551.2002","article-title":"Cloned genomic DNA of type porcine circovirus is infectious when injected directly into the liver and lymph nodes of pigs : characterization of clinical disease virus distribution and pathologic lesions","author":"Fenaux","year":"2002","journal-title":"J Virol"},{"key":"ref91","first-page":"164","article-title":"Concurrent infections are important for expression of porcine circovirus associated disease","author":"Opriessnig","year":"2012","journal-title":"Virus Res"},{"key":"ref201","first-page":"1","article-title":"live -
