Lumpy skin disease (LSD) is a transboundary, systemic, viral disease of cattle. The first outbreaks of LSD were reported in Lang Son Province of Vietnam (bordered to China), and an official document has been submitted to OIE on 1 November 2020. Here, we described first the genetic profiles of this pathogen based on four well-known marker regions.

Further investigation of the intergenic region of ASFVs isolated in the Capital Hanoi region showed two different variants, IGR I and IGR II, which were located between the I73R and I329L genes of the p72 genotype II ASFV strains. This finding suggests co-circulation of two ASFV variants in the domestic pig population in Vietnam.

ASFV was officially reported in Vietnam on 19 February 2019. The continued spread of ASFV has occurred in the whole country within 7 months.

However, the regulation of major histocompatibility complex (MHC) class I, MHC class II, and related genes by cytokines in chickens is not well understood. In the present study, we evaluated the influence of certain recently discovered chicken interleukins-i.

Purpose: To date, many kinds of classical swine fever (CSF) vaccines have been developed to protect against this disease. However, the efficacy of these vaccines to protect the pig against field CSF strains needs to be considered, based on circulating strains of classical swine fever virus (CSFV).
Materials And Methods: Recombinant E2-CSFV protein produced by baculovirus/insect cell system was analyzed by western blots and immunoperoxidase monolayer assay.
