FIELD: biotechnology.
SUBSTANCE: invention concerns a new strain of foot-and-mouth disease virus Aphtae epizooticae of type A, Picornaviridae family, Aphthovirus genus, deposited in the All-Russian State Collection of Exotic Types of Foot-and-Mouth Disease Virus and Other Animal Pathogens (GKSM) FGBI "ARRIAH" under registration number No.379 - dep/22-13 — GKShM FGBI "ARRIAH", A/Iran/2018 strain of type A of foot-and-mouth disease virus. The presented strain is reproduced in transplanted cell cultures of Siberian mountain ibex kidney (PSGK-30), pig kidney (IB-RS-2), newborn Syrian hamster kidney (VNK-21). In a continuous suspension culture of Syrian hamster kidney cells VNK-21/SUSP/ARRIAN for 11.25–0.12 hours of incubation, the concentration of 146S component of A/Iran/2018 strain of the foot and mouth disease virus has an average value of 1.99±0.09 μg/cm3 (67.93±0.97%), retaining the original characteristics when passaged in cell culture for 10 passages.
EFFECT: presented strain can be used for the manufacture of biopreparations for the diagnostics and specific prevention of FMD of type A and for control of the antigenic activity of FMD vaccines.
