The sequence of the spike (also called peplomer or E2) protein gene of the Mebus strain of bovine coronavirus (BCV) was obtained from cDNA clones of genomic RNA. The gene sequence predicts a 150,825 mol wt apoprotein of 1363 amino acids having an N-terminal hydrophobic signal sequence of 17 amino acids, 19 potential N-linked glycosylation sites, a(More)
The sequence of the hemagglutinin-esterase (HE) gene for the Mebus strain of bovine coronavirus was obtained from cDNA clones, and its deduced product is a 47,700-kilodalton apoprotein of 424 amino acids. Expression of the HE protein in vitro in the presence of microsomes revealed N-terminal signal peptide cleavage and C-terminal anchorage but not(More)
The nucleotide sequence between the spike and membrane protein genes in the bovine coronavirus (BCV) genome was determined by sequencing cDNA clones of the genome, and open reading frames potentially encoding proteins of 4.9, 4.8, 12.7, and 9.5 kDa, in that order, were identified. The 4.9- and 4.8-kDa proteins appear to be vestiges of an 11-kDa protein for(More)
The haemagglutinin molecule on the bovine enteric coronavirus has been identified as a glycoprotein of 140K composed of disulphide-linked subunits of 65K. In this study, we have shown the subunits to be identical by demonstrating an unambiguous amino-terminal amino acid sequence. The unglycosylated subunit was found to have an Mr of 42.5K and to undergo(More)
A method for purification of herpes simplex virus DNA from cell culture is described which yields highly purified viral DNA within 8 h. The method involves the freezing and thawing of virus-infected cells followed by isopycnic centrifugation of the lysate supernatant in cesium trifluoroacetate. It was found that this method recovered DNA from most of the(More)
We have analyzed the activity of a specific portion of the latency-associated transcript (LAT) promoter of three strains of herpes simplex virus type 1 (HSV-1) in neuronal and non-neuronal cell types. Restriction fragments containing the LAT promoter sequences and the 5'-end of the LATs were isolated from HSV-1 strains H129, +GC and KOS-63, sequenced and(More)
EcoRI fragments of herpes simplex virus I (HSV-1) strains H129 and +GC were cloned and theEcoRI andBglII restriction enzyme sites were mapped. Comparison of these enzyme sites with the sequence of HSV-1 strain 17syn+ demonstrated that allEcoRI sites were identical. For H129, theBglII sites were also found to match strain 17syn+BglII sites. With one(More)
PURPOSE In vivo, the ophthalmic dye rose bengal displays profound antiviral effects against herpes simplex virus (HSV)-1, thus limiting its utility in diagnosis of epithelial keratitis when used before viral culture is performed. In contrast, lissamine green B does not possess significant antiviral activity in vivo. To determine whether polymerase chain(More)
We have observed a cell-specific attenuation of herpes simplex virus type 1 strain 17syn+ in vivo that was dependent upon the cell type used to grow the virus. Direct corneal infection of rabbits with 17syn+ propagated in Vero cells caused 60% (6 of 10) to develop severe central nervous system (CNS) disease as evidenced by seizures and/or paralysis; all(More)
