TL;DR: This is the first isolate of SIRS virus in the United States that fulfills Koch's postulates in producing the respiratory form of the disease in gnotobiotic piglets and the first report of isolation and propagation of the virus on a continuous cell line (CL2621).
Journal ArticleDOI
Characterization of swine infertility and respiratory syndrome (SIRS) virus (isolate ATCC VR-2332).
David A. Benfield,Eric A. Nelson,James E. Collins,Lou Harris,Sagar M. Goyal,Deborah J. Robison,William T. Christianson,Robert B. Morrison,David E. Gorcyca,Dan Chladek +9 more
TL;DR: The characterization of an isolate of swine infertility and respiratory syndrome (SIRS) virus (ATCC VR-2332) is reported and it is indicated that this isolate is a fastidious, nonhemagglutinating, enveloped RNA virus.
Journal ArticleDOI
Experimental porcine reproductive and respiratory syndrome virus infection in one-, four-, and 10-week-old pigs.
Kurt Rossow,Elida M. Bautista,Sagar M. Goyal,Thomas W. Molitor,Michael P. Murtaugh,Robert B. Morrison,David A. Benfield,James E. Collins +7 more
TL;DR: Findings presented here indicate that interstitial pneumonia, lymphoid necrosis, and mononuclear myocarditis are characteristic lesions of PRRSV isolate ATCC VR-2332 infection in 1-, 4-, and lo-week-old pigs.
Journal Article
Experimental reproduction of swine infertility and respiratory syndrome in pregnant sows.
William T. Christianson,James E. Collins,David A. Benfield,L. Harris,D. E. Gorcyca,D. W. Chladek,Robert B. Morrison,Han S. Joo +7 more
TL;DR: On the basis of the findings, virus isolate ATCC VR-2332 causes the reproductive failure associated with SIRS.
Journal ArticleDOI
Control and elimination of porcine reproductive and respiratory syndrome virus.
Cesar Corzo,Enrique Mondaca,Spencer Wayne,Montserrat Torremorell,Scott Dee,Peter R. Davies,Robert B. Morrison +6 more
TL;DR: A voluntary regional program to involve all herds present within an area that has been relatively successful and reflects local leadership, a cooperative spirit, and a will to eliminate virus from the region is considered.
