The Participation of a Malignant Catarrhal Fever Virus and Mycoplasma bovis in the Development of Single and Mixed Infections in Beef and Dairy Cattle With Bovine Respiratory Disease

Frontiers in Veterinary Science, 2021
The bovine respiratory disease (BRD) complex is a multietiological and multifactorial disease associated with a wide range of viral and bacterial pathogens. This study evaluated the contribution of specific infectious disease agents in the development of

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 ...

Synthesis and Evaluation of in Vitro Biological Activity of 4-Substituted Arylpiperazine Derivatives of 1,7,8,9-Tetrachloro-10,10-dimethoxy-4-azatricyclo[5.2.1.02,6]dec-8-ene-3,5-dione

Molecules, 2009
A series of twenty arylpiperazine derivatives of 1,7,8,9-tetrachloro-10,10-dimethoxy-4-azatricyclo[5.2.1.02,6]dec-8-ene-3,5-dione have been prepared. These derivatives were tested in vitro with the aim of identifying novel lead compounds active against ...

Genomic sequencing and characterization of a Chinese isolate of Bovine viral diarrhea virus 2

Acta Virologica, 2009
The complete genomic sequencing and characterization of Bovine viral diarrhea virus (BVDV) isolate XJ-04 originated from cattle in China was described. The genomic RNA of the isolate was 12,284 nt long and contained short 5'- untranslated region (UTR), 3'-non-coding regions (NCR), and one open reading frame (ORF) encoding a large polyprotein of 3,895 ...

High frequency of bovine viral diarrhea virus type 2 in Southern Brazil

Virus Research, 2014
Ruminant pestiviruses can infect cattle populations worldwide and cause significant economic losses due to their impact on productivity and health. Knowledge of pestivirus diversity is important for control programs and vaccine development and for determining probable sources of infection.

Identification of a Bovine viral diarrhea virus 2 isolated from cattle in China

Acta Virologica, 2009
The identification and characterization of bovine viral diarrhea virus 2 (BVDV-2) strain SD-06 isolated from cattle in China is reported. We performed sequence analysis of 5'-untranslated region (5'-UTR) and E2 sequences and the identity at the nucleotide and amino acid level indicated that the isolate was closely related to BVDV-2.

Genotypic Characteristics of Bovine Viral Diarrhea Virus 2 Strains Isolated in Northern Italy.

Journal of Veterinary Medical Science, 2001
Two strains of Bovine viral diarrhea virus 2 (BVDV-2) were isolated from calves in northern Italy. Variations in the 5'-untranslated region (UTR) of the genome were studied by primary structure alignment and neighbor-joining method based phylogenetic tree analyses and by palindromic nucleotide substitutions at the three variable loci in the 5'-UTR ...
