Vaccination of birds other than chickens and turkeys against avian influenza.
of serological data. Whenever experimental challenge was performed in birds other than chickens and turkeys, vaccination using inactivated vaccines always protected against disease and mortality, ...
Prime-boost vaccination with a fowlpox vector and an inactivated avian influenza vaccine is highly immunogenic in Pekin ducks challenged with Asian H5N1 HPAI.
response and the lowest antibody increase after challenge were observed in the group of ducks whose immune system was primed with the fowlpox vectored vaccine and boosted with the inactivated vaccine, ...
Vaccination of calves using the BRSV nucleocapsid protein in a DNA prime-protein boost strategy stimulates cell-mediated immunity and protects the lungs against BRSV replication and pathology.
a lymphoproliferative response and IFN-gamma production. These responses were enhanced after protein boost. After challenge, mock-vaccinated calves displayed gross pneumonic lesions and viral replication in the lungs. In ...
Indirect foot-and-mouth disease vaccine potency testing based on a serological alternative.
(FMD) vaccine potency testing has historically been performed by experimentally infecting vaccinated cattle. A few alternative approaches to the in vivo challenge test based on the correlation between ...
Foot-and-mouth disease vaccine potency testing in cattle using homologous and heterologous challenge strains: precision of the "Protection against Podal Generalisation" test.
precision of the in vivo “Protection against Podal Generalisation” (PPG) FMD vaccine potency test in cattle using homologous (vaccine quality control) and heterologous (vaccine matching) viral challenge. The ...
DNA immunization with plasmids encoding fusion and nucleocapsid proteins of bovine respiratory syncytial virus induces a strong cell-mediated immunity and protects calves against challenge.
response drastically reduced viral replication, clinical signs, and pulmonary lesions after a highly virulent challenge. Moreover, calves that were further vaccinated with a killed-virus vaccine developed ...
Development of an M2e-specific enzyme-linked immunosorbent assay for differentiating infected from vaccinated animals.
negative for the M2 e ELISA s. Moreover, ducks inoculated with inactivated vaccine and challenged with a HPAI H5N1 seroconverted for antibodies to the M2 e peptide, with significantly different levels from ...
Efficacy of an inactivated and a fowlpox-vectored vaccine in Muscovy ducks against an Asian H5N1 highly pathogenic avian influenza viral challenge.
fowlpox-vectored TROVACTM- AIV H5 (rFP- AIV- H5) vaccine against an H5N1 highly pathogenic avian influenza challenge. Five-week-old Muscovy ducks were vaccinated with either H5N9-It (0.5 ml) or rFP- AIV- H5 (5 log10 ...
Application of non-structural protein antibody tests in substantiating freedom from foot-and-mouth disease virus infection after emergency vaccination of cattle.
large-scale preemptive culling of at-risk animals. Since vaccinated animals may become subclinically infected with FMDV following challenge exposure, it is necessary to either remove all vaccinates ...
Protection of rabbits against enteropathogenic Escherichia coli (EPEC) using an intimin null mutant.
examined its protective capacity. RESULTS: After verifying its complete loss of virulence, we used the attenuated strain in vaccination-challenge experiments in which complete protection against ...
