Immune Responses to Influenza D Virus in Calves Previously Infected with Bovine Viral Diarrhea Virus 2

Viruses, 2023
Bovine viral diarrhea virus (BVDV) induces immunosuppression and thymus depletion in calves. This study explores the impact of prior BVDV-2 exposure on the subsequent immune response to influenza D virus (IDV).

Bovine viral diarrhea virus 2 strains generate deletion viral genomes primarily in the NS2 region of the viral genome

Frontiers in Veterinary Science
Bovine viral diarrhea virus (BVDV) is a significant economic concern for the global cattle industry. This is attributed to the increased risk of transplacental BVDV infection during pregnancy, before sufficient maturation of the fetal immune system. This

Bovine Viral Diarrhea Virus Type 2-Induced Meningoencephalitis in a Heifer [PDF]

Veterinary Pathology, 2004
The brain from a 15-month-old, black female Angus, with a 48-hour history of central nervous system disease, was submitted to the Oklahoma Animal Disease Diagnostic Laboratory. Microscopic findings consisted of acute, multifocal meningoencephalitis, with neuronal degeneration and necrosis and gliosis. Viral isolation yielded noncytopathic bovine viral

Characterization of thymus-associated lymphoid depletion in bovine calves acutely or persistently infected with bovine viral diarrhea virus 1, bovine viral diarrhea virus 2 or HoBi-like pestivirus [PDF]

Archives of Virology, 2017
Naïve pregnant cattle exposed to pestiviruses between 40-125 days of gestation can give birth to persistently infected (PI) calves. Clinical presentation and survivability, in PI cattle, is highly variable even with the same pestivirus strain whereas the clinical presentation in acute infections is more uniform with severity of symptoms being primarily

Complete Genome Sequence of a Bovine Viral Diarrhea Virus 2 from Commercial Fetal Bovine Serum [PDF]

Journal of Virology, 2012
ABSTRACTWe isolated a bovine viral diarrhea virus (BVDV) from commercial fetal bovine serum and designated it HLJ-10. The complete genome is 12,284 nucleotides (nt); the open reading frame is 11,694 nt, coding 3,898 amino acids. Phylogenetic analysis indicated that this strain belongs to BVDV group 2.

Efficacy of Bovine Viral Diarrhea Vacchine Used in Japan against Bovine Viral Diarrhea Virus Type 2 Strain 890.

Journal of Veterinary Medical Science, 2003
Bovine viral diarrhea virus (BVDV) has been segregated into two genotypes, type 1 and type 2. To determine the efficacy of the commercially available bovine viral diarrhea type 1 vaccine used in Japan against BVDV type 2, calves were infected with BVDV type 2 strain 890 4 weeks after administration of the vaccine.

Hypomyelination Associated With Bovine Viral Diarrhea Virus Type 2 Infection in a Longhorn Calf [PDF]

Veterinary Pathology, 2010
A newborn Longhorn heifer calf presented with generalized tremors, muscle fasciculations, ataxia, and nystagmus. At necropsy, no gross central nervous system lesions were observed. Histologically, the brain and spinal cord had mild to moderate diffuse microgliosis and astrocytosis, minimal nonsuppurative encephalitis, and decreased myelin staining ...
