Описание:
Spring Viremia of Carp Virus (SVCV) or Rhabdovirus carpio is the causative agent of the fish disease, Spring Viremia of Carp (SVC). Genetic relationships between 35 SVCV genogroup Ia isolates were determined based on the nucleotide sequence of the phosphoprotein (P) gene and glycoprotein (G) genes. Phylogenetic analysis based on P-gene sequences revealed 2 distinct subgroups within the SVCV genogroup Ia, designated SVCV Iai and Iaii,and suggests at least 2 independent introductions of the virus in the USA in 2002. Combined P and G sequence data support the emergence of SVCV in Illinois,USA and Lake Ontario,Canada,from the initial outbreak in Wisconsin,USA,and demonstrate a close genetic link to viruses isolated during routine import checks on fish brought into the UK from Asia. There was strong phylogenetic support for an Asian origin for 9 of 16 UK viruses isolated from fish imported from Asia. The remaining portion of this book deals with biosecurity on ornamental fish farms,...Похожие книги
