Abstract:
African swine fever virus (ASFV) isolated in 2016–2017 from domestic pigs and wild boars in eight regions of the Russian Federation has comparable biological characteristics: it is virulent, causes the death of animals with signs of acute and overactive forms without the manifestation of a complete symptom complex of clinical and pathologic symptoms, possesses hemadsorption and accumulates in the initial (swine leukocytes, SBM) and transplantable (A4C2/9k) cell cultures in titres 5.5–7.5 and 3.5–5.25 log HAU/₅₀cm³, respectively. The studied isolates belong to the eighth serotype and the second genotype. According to these indicators, the ASF virus is comparable with the virus isolates circulating in Russia since 2007.
