Novel genomic targets for proper subtyping of bovine viral diarrhea virus 1 (BVDV-1) and BVDV-2
Virus Genes, 2023Whole-genome phylogenetic analysis, the most suitable strategy for subtyping bovine viral diarrhea virus 1 (BVDV-1) and BVDV-2, is not feasible for many laboratories. Consequently, BVDV isolates/strains have been frequently subtyped based on analysis of single genomic regions, mainly the 5' untranslated region (UTR). This approach, however, may lead to

Occurrence of a second strain of
SIR, — We wish to draw attention to the occurrence of a second strain of bovine viral diarrhoea virus type 2 (bvdv-2) in the uk. This strain was detected and isolated as a consequence of clinical investigations carried out by the Veterinary Laboratories Agency (vla) in cooperation with ...

Pig BVDV-2 non-structural protein (Npro) links to cellular antiviral response in vitro
Virus Genes, 2016In this study, we constructed for the first time a full-length cDNA clone of pig-original bovine viral diarrhea virus 2 (BVDV-2) strain SH-28, modified the cDNA clone (pASH28) for mutant pASHΔNpro and derived virus strain vASHΔNpro by deleting the genomic region encoding the Npro polypeptide, and examined significance of protein Npro for antiviral ...

Border disease‐like clinical signs in sheep caused by a BVDV‐2 type d
Veterinary Record Case Reports, 2017The present paper accounts for the study of an outbreak of abortions within a sheep herd over a span of three months. To this purpose, one of the aborted fetuses that tested positive for bovine viral diarrhoea virus (BVDV), specifically BVDV‐2, was analysed by RT‐qPCR. Afterwards, sera from all the animals in the herd were collected in order to perform

Two studies were performed in pregnant heifers to determine whether inoculation with two bovine viral diarrhoea viruses (BVDV), one BVDV-1 and one BVDV-2, inoculated separately into either nostril, results in fetal infection with both viruses.

The purpose of this study was to compare clinical and virological differences between non-cytopathic (ncp) bovine viral diarrhea virus (BVDV)-1 and ncp BVDV-2 isolated from Korean field cases. Each five naïve calves were experimentally infected with Korean ncp BVDV-1 or BVDV-2 isolates.

Efficacy of attenuated (att) bovine viral diarrhea virus (types 1 and 2) as antigen fractions in a modified-live multivalent vaccine were evaluated following single, subcutaneous (SC) administration and intranasal (IN) challenge 35 to 38 d after vaccination, with either virulent BVDV-1b (Study 1) or BVDV-2 (Study 2) viruses in young calves.

A non-cytopathic strain of BVDV-2 was isolated from a batch of live infectious bovine rhinotracheitis (IBR) vaccine, and inoculated intranasally into four 3-month-old calves. Severe signs of disease developed by days 4 and 6 in three of the calves, free of BVDV and antibodies to BVDV, that had been exposed to the virus.

The reproduction effects of bovine viral diarrhea virus type-2 (BVDV-2) infection were investigated in ewes inoculated with a non-cytopathic BVDV-2 isolate at three stages of gestation. Virus inoculation was followed by a transient viremia, accompanied by a transient and mild hyperthermia and nasal discharge in a few animals.
