Infections of horses with equine herpesvirus type 1 (EHV-1) have garnered new attention over the last few years. Devastating outbreaks occurring worldwide, primarily of the neurologic form of the disease, have resulted in a reassessment of the control strategies, and particularly the prophylactic measures, that are necessary to keep the infection and spread(More)
Bovine viral diarrhea virus (BVDV) is an economically important pathogen of cattle that is maintained in the population by persistently infected animals. Virus infection may result in reproductive failure, respiratory disease and diarrhoea in naïve, susceptible bovines. Here, the construction and characterization of a novel vectored vaccine, which is based(More)
The immunogenicity in horses of a recombinant equine herpesvirus type 1 (EHV-1) vaccine expressing West Nile virus (WNV) prM and E proteins was studied. To construct the recombinant EHV-1, two-step en passant mutagenesis was employed for manipulation of a bacterial artificial chromosome (BAC) of vaccine strain RacH. Recombinant EHV-1 stably expressed the(More)
Vaccination is commonly used to control equine respiratory pathogens such as equine herpesvirus type 1 (EHV-1) and equine influenza virus (EIV). Here, we describe the generation and characterization of a recombinant EHV-1 modified live virus vaccine (MLV) based on a recent abortogenic EHV-1 strain, NY03. The immunogenicity and efficacy of the MLV was tested(More)
A vectored vaccine based on equine herpesvirus type 1 (EHV-1) was generated as an alternative for safe and efficient prophylaxis against Venezuelan equine encephalitis virus (VEEV) infection. Two-step (en passant) Red mutagenesis was used to insert VEEV structural genes into an infectious clone of EHV-1 vaccine strain RacH. The recombinant virus, rH_VEEV,(More)
In 2004, canine influenza virus (CIV) was identified as a respiratory pathogen of dogs for the first time and found to be closely related to H3N8 equine influenza virus (EIV). We generated a recombinant vectored vaccine that expresses H3 of a recent isolate of EIV using equine herpesvirus type 1 (EHV-1) as the delivery vehicle. This EHV-1 vectored vaccine(More)
