Description
Summary:The brains of 10 infected pigs were examined for histopathology and presence of African swine fever virus (ASFV) DNA ASFV infection induces inflamed meninges, cerebral edema and vascular thrombosis, as well as subdural hematomas. Slight tension in the dura mater, flattening of the gyri and narrowing of the sulci were also observed at four days post infection (dpi). Enlarged perivascular spaces were detected for most vessels of the brain after three to four dpi. Considerable lymphocytic infiltration of the brain tissue was observed at the terminal stage of disease. ASFV was present in all investigated areas of brain beginning from three to four dpi. The isolated virus do not differ from the used in present study Georgia 2007 strain.
