Identification of two novel B cell epitopes on E184L protein of African swine fever virus using monoclonal antibodies.

African swine fever virus (ASFV) is a large double-stranded DNA virus with a complex structural architecture and encodes more than 150 proteins, where many are with unknown functions. E184L has been reported as one of the immunogenic ASFV proteins that may contribute to ASFV pathogenesis and immune evasion. However, the antigenic epitopes of E184L are not yet characterized.

Development of a Real-Time qPCR Method for the Clinical Sample Detection of Capripox Virus.

Capripox viruses (CaPVs), including sheep pox virus (SPV), goat pox virus (GPV), and lumpy skin disease virus (LSDV), are the cause of sheep pox (SPP), goat pox (GTP), and lumpy skin disease (LSD) in cattle. These diseases are of great economic significance to farmers, as they are endemic on farms and are a major constraint to international trade in livestock and their products. Capripoxvirus (CaPV) infections produce similar symptoms in sheep and goats, and the three viruses cannot be distinguished serologically.

[Construction of a recombinant HVT virus expressing the HA gene of avian influenza virus H5N1 via Rde/ET recombination system].

Objective: In recent years,manipulation of large herpesvirus genomes has been facilitated by using bacterial artificial chromosome (BAC) vectors. We have previously reported the construction of the BAC clones (HVT BACs) of herpesvirus of turkey (HVT). With these BAC clones in hand,we manipulated the genome of HVT by utilizing Red/ET recombination system, and developed a biologically safe live vaccine based on the HVT BACs.

Construction of an infectious Marek's disease virus bacterial artificial chromosome and characterization of protection induced in chickens.

Marek's disease virus (MDV) is a highly oncogenic alphaherpesvirus that induces rapid-onset T-cell lymphoma in poultry. The complete genome of the avirulent vaccine strain MDV-814 was cloned as an infectious bacterial artificial chromosome (BAC) using an 8.8-kb fragment containing the self-designed selective marker guanosine phosphoriboxyl transferase.

[Reconstituting turkey herpesvirus with bacterial artificial chromosome clones].

Unlabelled: Herpesvirus of turkey (HVT) is an alpherpesvirus and widely used as a live vaccine against Marek's disease (MD) because of its antigenic relationship with Marek's disease virus (MDV).

Objective: The aim of this study was to construct Herpesvirus of turkey Fc126 strain as an infectious bacterial artificial chromosome (BAC).

Methods: Using the selection marker Eco-gpt (Xanthine-guanine phosphoribosyl transferase)(1.

[Construction of Marek's disease virus serotype 814 strain as an infectious bacterial artificial chromosome].

The aim of this study was to construct the complete genome of Marek's disease virus serotype 814 strain as an infectious bacterial artificial chromosome (BAC). Using self-designed selection marker Eco-gpt (1.3 kb) and BAC vector pBeloBAC11 (7.
