FGBI ARRIAH conducts experimental studies of new infections

In June-July 2022, in the FBGU “Federal Center for Animal Health” subordinate to ROSSELKHOZNADZOR, employees of the reference laboratory for diagnosing foot and mouth disease for the first time in the Russian Federation conducted an experiment on experimental reproduction of Seneca Valley virus infection on naturally susceptible animals (pigs 4 months old). As a result of the experimental studies, highly active blood sera were obtained from convalescent pigs, which will later be used to develop a method for indicating infection.

Reference.
Seneca Valley Virus (Senecavirus A, Seneca Valley Virus) is a non-enveloped RNA virus with a diameter of 30 nm. The virus was identified in 2002 and classified as the only representative strain of the Senecavirus A species in the new Senecavirus genus of the Picornaviridae family. it was first identified as a contaminant in cell culture, but the natural hosts are now thought to be pigs and possibly cattle.

The disease has been described in Australia, North America and Europe, but recent reports from Brazil and the US indicate an increase in the prevalence of the virus in swine herds. The Seneca Valley virus is not included in the list of especially dangerous infections of the Russian Federation, however, it causes a clinical picture indistinguishable from foot and mouth disease, vesicular stomatitis and vesicular disease of pigs.

The risk of introducing infection with breeding pigs imported into the Russian Federation indicates the need to develop diagnostic methods for the timely identification of the pathogen or antibodies to it in the differential diagnosis of foot-and-mouth disease and other especially dangerous infections with vesicular syndrome.
