Spring Viremia of Carp Virus in Minnehaha Creek, Minnesota

J Aquat Anim Health. 2012 Dec;24(4):232-7. doi: 10.1080/08997659.2012.711267.


Spring viremia of carp virus (SVCV) causes a highly contagious and serious disease of freshwater cyprinid fishes, generating significant economic and ecological impacts throughout the world. The SVCV is therefore listed as a notifiable pathogen by the International Organization for Animal Health. In June 2011, a significant mortality event of wild common carp Cyprinus carpio occurred in Minnehaha Creek near its confluence with Mississippi River Pool 2 in Minneapolis, Minnesota. Clinical signs of moribund fish included hemorrhagic lesions in the skin, eyes, and internal adipose tissue. The SVCV was isolated from pooled kidney and spleen of the fish. Rhabdovirus particles were seen upon examination of infected cell culture fluid by electron microscopy. The virus was confirmed to be SVCV subtype Ia by reverse transcription PCR and sequencing. This is the first report of SVCV within the state of Minnesota and the ninth documented case in North America.
