A glycoprotein E gene-deleted bovine herpesvirus 1 as a candidate vaccine strain
A bovine herpesvirus 1 (BoHV-1) defective in glycoprotein E (gE) was constructed from a Brazilian genital BoHV-1 isolate, by replacing the full gE coding region with the green fluorescent protein (GFP) gene for selection. Upon co-transfection of MDBK cells with genomic viral DNA plus the GFP-bearing gE-deletion plasmid, three fluorescent recombinant clones were obtained out of approximately 500...
متن کاملProtection induced by a glycoprotein E-deleted bovine herpesvirus type 1 marker strain used either as an inactivated or live attenuated vaccine in cattle
BACKGROUND Bovine herpesvirus type 1 (BoHV-1) is the causative agent of respiratory and genital tract infections; causing a high economic loss in all continents. Use of marker vaccines in IBR eradication programs is widely accepted since it allows for protection of the animals against the disease while adding the possibility of differentiating vaccinated from infected animals.The aim of the pre...
متن کاملIsolation of Bovine Herpesvirus-1 (BoHV-1) From Latently Infected/Carrier Cattle in Ahvaz
Bovine herpesvirus 1 (BoHV-1) is one of the most important infectious viruses of cattle which is considered as the causative agent of several clinical conditions in this species. Hence, we tried to isolate a local strain of the virus from carrier cattle in Ahvaz based on a strategy for reactivation of the latent infection in hosts having antibodies against the virus. Thus, 20 cattle were examin...
متن کاملBovine herpesvirus 1 VP22 enhances the efficacy of a DNA vaccine in cattle.
For this study, the intercellular trafficking ability of bovine herpesvirus 1 (BHV-1) VP22 was applied to improve the efficacy of a DNA vaccine in calves. A plasmid encoding a truncated version of glycoprotein D (tgD) fused to VP22 was constructed. The plasmid encoding tgD-VP22 elicited significantly enhanced and more balanced immune responses than those induced by a plasmid encoding tgD. Furth...
متن کاملEfficacy of a live bovine herpesvirus type 1 marker vaccine under field conditions in three countries.
The performance of a live marker vaccine for bovine herpesvirus type 1 (bhv-1) was studied in the field in three European Union countries with different farming conditions. The progress in the eradication of the virus was followed in a large herd in Germany and one in Italy, and a major serological survey involving 147 farms was conducted in Hungary. Commercial batches of the same vaccine were ...
