Although ongoing evidence suggests that porcine circovirus type\u20102 (PCV2) is the causal agent of PMWS, the host immune system appears to have a crucial role in the PMWS pathogenesis of PCV2\u2010affected pigs. Owing to difficulties in producing a biologically pure form of PCV2 devoid of the other viral agents commonly present in swine tissues, we decided to use a tandem\u2010cloned PCV2 DNA providing highly pure grade reagent in order to monitor the virulence of PCV2 alone or with an immunostimulating co\u2010factor, granulocyte\u2010macrophage colony\u2010stimulating factor (GM\u2010CSF). A single intramuscular injection of tandem\u2010cloned PCV2 DNA into 5\u2010week\u2010old piglets produced plasmid to viral genome progeny and infectious particles as early as 8 days post\u2010injection in all the organs tested (the lung, the tonsil and the inguinal, mesenteric, bronchial and upper\u2010right axial lymph nodes). The initial plasmid load was not detected with the help of primers designed to specifically detect the acceptor plasmid, thus confirming the replication of the viral genome. Despite the presence of a high level of PCV2 genome copies in the lymphoid organs \u2013 the tonsil and the lung \u2013 and the presence of infectious particles, no detectable clinical manifestations or pathological lesions were observed in the transfected pigs over the period of observation, regardless of whether they had been co\u2010injected with plasmid containing GM\u2010CSF DNA or had received plasmid containing PCV2 DNA alone. GM\u2010CSF encoding DNA injection had no significant effect on viral replication or on the production of viral particles and appearance of the disease.<\/jats:p>","DOI":"10.1111\/j.0959-9673.2005.00409.x","type":"journal-article","created":{"date-parts":[[2005,1,27]],"date-time":"2005-01-27T17:04:50Z","timestamp":1106845490000},"page":"33-43","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Effect of granulocyte\u2010macrophage colony\u2010stimulating factor on post\u2010weaning multisystemic wasting syndrome in porcine circovirus type\u20102\u2010transfected piglets"],"prefix":"10.1111","volume":"86","author":[{"given":"Christophe","family":"Loizel","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philippe","family":"Blanchard","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B\u00e9atrice","family":"Grasland","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Dory","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aur\u00e9lie","family":"Oger","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anne\u2010C\u00e9cile","family":"Nignol","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roland","family":"Cariolet","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andr\u00e9","family":"Jestin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,1,27]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0022-1759(94)90396-4"},{"key":"e_1_2_6_3_1","first-page":"1","article-title":"Premiers r\u00e9sultats du CNEVA sur le d\u00e9p\u00e9rissement fatal du porcelet en fin de post\u2010sevrage","volume":"834","author":"Albina E.","year":"1996","journal-title":"Suppl.
