Among 54 transcripts expressed in a temporal cascade during lytic infection with bovine herpesvirus 1, we have previously identified three major immediate-early (IE) RNAs, IER4.2 (4.2 kb), IER2.9 (2.9 kb), and IER1.7 (1.6 to 1.8 kb depending on the virus strain) transcribed from the HindIII C genome region (U. V. Wirth, K. Gunkel, M. Engels, and M.(More)
Bovine herpesvirus 1 (BHV-1) contains three major immediate-early (IE) genes involved in regulation of the productive cycle of replication. Two spliced IE RNAs, IER4.2 (4.2 kb) and IER2.9 (2.9 kb), are under the control of a single promoter; IER1.7 (1.7 kb) is transcribed from a different promoter in the opposite direction. Examining the kinetics of(More)
Kinetic analysis of the two divergent immediate early (IE) transcription units of bovine herpesvirus 1 (BHV-1) revealed an unexpected behaviour. The IE1.7 promoter was not turned off at the end of the IE period but acted as a late promoter, unlike the adjacent IE4.2/2.9 promoter which was active only under IE conditions. The genome region specifying the(More)
Northern (RNA) blot analysis was used to determine the spatial and temporal distribution of bovine herpesvirus 1 (BHV-1) transcripts. Total RNA was isolated from Madin-Darby bovine kidney cells which had been infected with BHV-1.2b strain K22 or BHV-1.1 strain Jura in the presence or absence of metabolic inhibitors. Cloned restriction fragments representing(More)
We report the nucleotide sequence of the 19-kb HindIII fragment B of bovine herpesvirus 1 (BHV-1) DNA and adjacent parts of the HindIII A and L fragments, which together span a still completely uncharted 30-kb region located between the glycoprotein H gene and the right end of the unique long segment. The analysis revealed 17 complete open reading frames(More)
Large simian virus 40 tumor antigen was bound as immune complex to protein A-Sepharose and then subjected to limited proteolysis which yielded several discrete fragments. Primary structures near the cleavage sites were determined by radiosequencing techniques. Experimental data for five fragments matched an amino acid sequence predicted from a nucleotide(More)
The nucleotide sequence of a 10.5 kb region (map position 0.332 to 0.410) of bovine herpesvirus type 1 (BHV-1) was determined. This region contained three open reading frames (ORFs) homologous to herpes simplex virus DNA polymerase catalytic subunit (DNApol, UL30), major DNA-binding protein (MDBP, UL29) and ICP18.5 assembly protein (ICP18.5, UL28). The(More)
Molecular virology has served to establish bovine herpesvirus 1 (BHV-1) as the prototype member of ruminant herpesviruses. Based on the genomic sequence of the virus, we aim to identify and characterize virus-specified components, to explain their concerted action, and to predict how the chain of events during the lytic and latent phases of the viral life(More)
Bovine herpesvirus 1 (BHV-1) specifies and unspliced early 2.6-kb RNA (ER2.6) which is 3' coterminal with exon 2 of the 2.9-kb immediate-early (IE) RNA. The two transcripts have a common open reading frame (676 codons). The predicted protein, designated BHV-1 infected cell protein 0 (BICP0), contains a zinc finger domain with homology to ICP0 of herpes(More)
Using a previously developed filter adsorption technique, the inactivation of a human rotavirus, a coxsackievirus B5, and a bovine parvovirus was monitored during sludge treatment processes. During conventional anaerobic mesophilic digestion at 35 to 36 degrees C, only minor inactivation of all three viruses occurred. The k' values measured were 0.314 log10(More)
