Patterns of alveolar macrophage activation upon attenuated and virulent African swine fever viruses in vitro.

Article Synopsis
- The study examined how two strains of African swine fever (ASF) viruses affect the activation of porcine alveolar macrophages (AM), noting differences in immune response.
- Cells infected with the virulent ASFV-Georgia2007 showed unique M1 polarization and changes in morphology, resulting in lower synthesis of certain interferons compared to those infected with the attenuated strain ASFV-BA71V.
- The findings suggest that the more virulent ASFV-Georgia2007 reduces the antiviral response of AM, indicating that the evolutionary decrease of ASFV virulence is linked to changes in host immune system regulation.
Glomerulonephritis due to African swine fever (ASF) is well documented. However, there is absence of good understanding of mechanisms involved in the development of pathology development. This study examines glomerulonephritis in association with acute infection induced by II genotype (Georgia 2007) of ASF virus.

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.

Materials And Methods: A total of 10 pigs were inoculated with ASF virus (ASFV) (genotype II) in the study of the red blood cells (RBCs), blood and urine biochemistry in the dynamics of disease.
Results: The major hematological differences observed in ASFV infected pigs were that the mean corpuscular volume, mean corpuscular hemoglobin, and hematocrits were significantly decreased compared to controls, and the levels of erythropoietin were significantly increased.
