Assessment of the efficacy of an attenuated live marker classical swine fever vaccine (Flc-LOM-BErns) in pregnant sows.

Vaccine, 2019
Here, we constructed an attenuated live marker classical swine fever (CSF) vaccine (Flc-LOM-BErns) to eradicate CSF. This was done by taking infectious clone Flc-LOM, which is based on an attenuated live CSF vaccine virus (LOM strain), and removing the ...

Markers and Vaccines

1978
Publisher Summary This chapter is concerned with virus vaccines and their genetically conditioned markers. For many years, virus vaccines have been in fact the only effective means for reducing the morbidity of virus infections, and thus far biogenic, semisynthetic, and synthetic antiviral substances have failed to give satisfactory results. Although

Laboratory markers for over-attenuation of mumps vaccine virus

Vaccine, 1988
The properties of mumps vaccine virus (Leningrad-3 strain) gradually changed upon passaging in quail embryo fibroblasts, the substrate normally used for mumps vaccine production in the USSR. Alterations were extremely noticeable in the over-attenuated (38th passage) virus variant, and involved (a) poor, if any, antibody response in guinea-pigs, (b ...

Inactivated bovine herpesvirus 1 marker vaccines are more efficacious in reducing virus excretion after reactivation than a live marker vaccine

Vaccine, 1997
A comparative study was carried out to evaluate the efficacy of three bovine herpesvirus 1 (BHV1) marker vaccines to reduce the reexcretion of virus after reactivation of latent BHV1. A live gE-negative vaccine, an inactivated gE-negative vaccine and an experimental gD-subunit vaccine were tested in three identical experiments in which cattle, latently

Experiences with two BHV1 marker vaccines

The Bovine Practitioner, 1997
Both marker vaccines tested were deleted vaccines, one had a gG, the other a gE deletion. The gG deleted vaccine was inactivated the gE deleted vaccine had a live and an inactivated form. The object of the trial was to evaluate these vaccines in heifers and calves. Twenty young heifers were used for the inactivated deleted vaccines and 16 four week old

Improvement of serological discrimination between herpesvirus-infected animals and animals vaccinated with marker vaccines

Veterinary Microbiology, 2002
Control/eradication plans of bovine herpesvirus 1 (BHV1) and suid herpesvirus 1 (SHV1) infections involve vaccination with inactivated or attenuated gE-deleted marker vaccines and associated companion serological tests to discriminate naturally infected from vaccinated animals.

Overview of marker vaccine and differential diagnostic test technology

Biologicals, 2005
Recent advances in molecular biology, immunology, microbiology, genetics and microbial pathogenesis have lead to the development of a wide variety of new approaches for developing safer and more effective vaccines based on designs such as subunit vaccines, gene deleted vaccines, live vectored vaccines, and DNA mediated vaccines. Technology tools can be

Vaccination markers: designing unique antigens to be added to vaccines to differentiate between natural infection and vaccination

Vaccine, 2005
Some important vaccines, including ones against tuberculosis (Tb) and foot-and-mouth disease (FMD), are not used in many developed countries because there is no simple way to differentiate between vaccine-induced immunity and infection. Eliminating major protein antigens has not succeeded in the cases of Tb, FMD and some other vaccine preparations ...

Markers of Cell-Mediated Immunity After Vaccination with an Inactivated, Whole-Cell Q Fever Vaccine

Journal of Infectious Diseases, 1988
A clinical trial of Q fever vaccine in four South Australian abattoirs showed apparently complete protection against natural infection; however, only 50%-60% of vaccinees developed complement-fixing or immunofluorescent antibody after vaccination. Cell-mediated immunity to Coxiella burnetii antigens, as measured by an index of lymphoproliferative ...

Protective immunity in cattle following vaccination with conventional and marker bovine herpesvirus-1 (BHV1) vaccines

Vaccine, 1997
The efficacy of two experimental subunit gD vaccines and two commercial whole virus vaccines was determined in a bovine herpesvirus-1 (BHV1) challenge trial. Full-length gD and a truncated, secreted form of gD (tgD) were produced using a vaccinia virus expression system and purified by affinity chromatography.
