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.

The present study describes the gross, histopathologic lesions of the heart arising in pigs infected with acute African Swine Fever (ASF) and their biochemical profile. Ten pigs were infected by intramuscular injection of ASF virus (Georgia 2007). Selected heart samples were submitted for histopathological examination and Hematoxylin-Basic Fuchsin-Picric Acid (HBFP) staining. Enzymatic abnormalities were evaluated by measurement of main cardiac markers, whose activity increased during the early stage of infection, with histopathological changes occurring later. Minor myocardial haemorrhages were first observed at four days post infection (dpi), and were noted in all pigs by six dpi. Early vascular response to infection was manifested as increased capillary permeability leading to diapedesis and the retention of blood cells in myocardial tissue. The terminal stage of the disease was characterised by massive haemorrhages caused by the rupture of large vessels. Substantial ischemic areas were detected by HBFP staining at the terminal stages of ASF.
