Isolation and Characterization of Seneca Valley from pig Transboundary
spread to the Mink Infection
Abstract
Seneca Valley Virus (SVV) infection was recently spread the pig farm in
the Canada, American and China, human, mice and housefly have been the
host and reservoirs. Although such cross-species transmission events
result in limited onward in the new cross-species transmission,
sustained outbreak have posed a new mammalian host. Thus, to determine
whether mink was one of a new mammalian host in our study with the
molecular characteristics of isolated SVA genomes, challenge,
pathological study, and immune respond. Here, our research was the first
systemic analysis on a new isolation strain of SVV from pig, the new
strain infected the mink in oral and intestine, which produced the
pathological change in the intestine. And the SVV could stimulate the
specific neutralizing antibody. This study highlights the importance of
identifying SVV infection in the mink and host as a mutational pressure
for the virus evolution that could threaten livestock, public health and
economic growth.
