Dynamics of Serological and Mucosal Antibody Responses against African Swine Fever Viruses in Experimentally Infected Pigs

Transboundary and Emerging Diseases, Volume 2023, Issue 1, 2023., 2023
African swine fever virus (ASFV) is a lethal swine pathogen, and there is no effective vaccine or treatment available for ASFV infection. Recently, the occurrence of ASFV genotype I and genotype II natural mutants that manifest as subacute, longer‐incubation, or persistent infections poses threats to preventing ASFV infection.

Detection of African Swine Fever Virus Genotype II in West Africa (2020) and Its Co-Circulation With Endemic Genotype I: Implications for Pig Production. [PDF]

Transbound Emerg Dis
African swine fever (ASF) is a highly devastating disease of domestic pigs caused by the ASF virus (ASFV). Historically, only ASFV Genotype I was known to circulate in West Africa. However, Genotype II has recently emerged in Nigeria, Ghana, and Benin for the first time. Between 2017 and 2023, suspected ASF outbreaks were reported in Burkina Faso, Côte

Novel method for sub‐grouping of genotype II African swine fever viruses based on the intergenic region between the A179L and A137R genes

Veterinary Medicine and Science, Volume 8, Issue 2, Page 607-609, March 2022., 2022
We report the development of a novel method for sub‐grouping genotype II African swine fever virus based on the intergenic region between the A179L and A137R genes. We have identified an insertion or deletion of an 11‐nucleotide sequence that may help analysis of the evolution and relationships between geographically separated outbreaks.

Pathological investigation and viral antigen distribution of emerging African swine fever in Vietnam

Transboundary and Emerging Diseases, Volume 68, Issue 4, Page 2039-2050, July 2021., 2021
Abstract African swine fever (ASF) is emerging in Vietnam and poses a continuing severe threat to the swine industry. A histopathological study of clinical samples collected during the May to July 2019 outbreak of ASF was performed to determine the characteristic lesions. We analysed samples from eight ASFV‐infected farms.

The Production of Recombinant African Swine Fever Virus Lv17/WB/Rie1 Strains and Their In Vitro and In Vivo Characterizations [PDF]

, 2023
18 Pág.Lv17/WB/Rie1-Δ24 was produced via illegitimate recombination mediated by low-dilution serial passage in the Cos7 cell line and isolated on PAM cell culture. The virus contains a huge ~26.4 Kb deletion in the left end of its genome.

Rapid emergence of African swine fever virus variants with different numbers of a tandem repeat sequence in South Korea

Transboundary and Emerging Diseases, Volume 68, Issue 4, Page 1726-1730, July 2021., 2021
Abstract African swine fever virus variants with different numbers of a 10‐bp tandem repeat were isolated in South Korea soon after being identified in wild boar. The short emergence periods and sympatric distributions within a narrow geographical region suggest that the variants were sporadically generated in the pre‐existing viral population.
