A commercial cell line (CL262 1) was used for the propagation of the virus for all assays. Laboratory studies indicate that this isolate is a fastidious, nonhemagglutinating, enveloped RNA virus. Cesium chloride-purified virions visualized by electron microscopy were spherical particles with an average diameter of 62 nm (range: 48\u201383 nm) and a 25\u201330 nm core surrounded by an envelope. Virus replication was restricted to the cytoplasm, as demonstrated by immunofluorescence. The virus did not react serologically with antisera to several common porcine viruses or with antisera to known viruses in the alphavirus, rubivirus, pestivirus, and ungrouped lactic dehydrogenase virus genera of the Togaviridae. However, convalescent sow sera and rabbit hyperimmune sera neutralized the SIRS virus at titers of 1:256 and 1:512, respectively. The virus was stable at 4 and \u221270 C, but was labile at 37 and 56 C. The properties of this isolate of SIRS virus resemble those of the family Togaviridae but do not match the described genera.<\/jats:p>","DOI":"10.1177\/104063879200400202","type":"journal-article","created":{"date-parts":[[2011,5,12]],"date-time":"2011-05-12T16:10:00Z","timestamp":1305216600000},"page":"127-133","source":"Crossref","is-referenced-by-count":614,"title":["Characterization of Swine Infertility and Respiratory Syndrome (SIRS) Virus (Isolate ATCC VR-2332)"],"prefix":"10.1177","volume":"4","author":[{"given":"David A.","family":"Benfield","sequence":"first","affiliation":[{"name":"Department of Veterinary Science, South Dakota State University, Brookings, SD 57007"}]},{"given":"Eric","family":"Nelson","sequence":"additional","affiliation":[{"name":"Department of Veterinary Science, South Dakota State University, Brookings, SD 57007"}]},{"given":"James E.","family":"Collins","sequence":"additional","affiliation":[{"name":"Department of Veterinary Diagnostic Medicine, College of Veterinary Medicine, University of Minnesota, St. Paul, MN 55108"}]},{"given":"Lou","family":"Harris","sequence":"additional","affiliation":[{"name":"Boehringer Ingelheim Animal Health, Inc., St. Joseph, MO 64502"}]},{"given":"Sagar M.","family":"Goyal","sequence":"additional","affiliation":[{"name":"Department of Veterinary Diagnostic Medicine, College of Veterinary Medicine, University of Minnesota, St. Paul, MN 55108"}]},{"given":"Deborah","family":"Robison","sequence":"additional","affiliation":[{"name":"Department of Veterinary Science, South Dakota State University, Brookings, SD 57007"}]},{"given":"William T.","family":"Christianson","sequence":"additional","affiliation":[{"name":"Department of Clinical and Population Sciences, College of Veterinary Medicine, University of Minnesota, St. Paul, MN 55108"}]},{"given":"Robert B.","family":"Morrison","sequence":"additional","affiliation":[{"name":"Department of Clinical and Population Sciences, College of Veterinary Medicine, University of Minnesota, St. Paul, MN 55108"}]},{"given":"David","family":"Gorcyca","sequence":"additional","affiliation":[{"name":"Boehringer Ingelheim Animal Health, Inc., St. Joseph, MO 64502"}]},{"given":"Dan","family":"Chladek","sequence":"additional","affiliation":[{"name":"Boehringer Ingelheim Animal Health, Inc., St. Joseph, MO 64502"}]}],"member":"179","published-online":{"date-parts":[[1992,4,1]]},"reference":[{"key":"bibr1-104063879200400202","doi-asserted-by":"publisher","DOI":"10.1128\/JCM.16.1.186-190.1982"},{"key":"bibr2-104063879200400202","first-page":"9","volume":"27","author":"Christianson WT","year":"1991","journal-title":"Pig Vet J"},{"key":"bibr3-104063879200400202","doi-asserted-by":"publisher","DOI":"10.1177\/104063879200400201"},{"key":"bibr4-104063879200400202","unstructured":"Commission of the European Communities, Directorate General for Agriculture: 1991, Porcine respiratory and reproductive failure syndrome.
