The internal initiation of translation in bovine viral diarrhea virus RNA depends on the presence of an RNA pseudoknot upstream of the initiation codon

Virology Journal, 2007
Background Bovine viral diarrhea virus (BVDV) is the prototype representative of the pestivirus genus in the Flaviviridae family. It has been shown that the initiation of translation of BVDV RNA occurs by an internal ribosome entry mechanism mediated by ...

In vitro method to evaluate virus competition between BVDV-1 and BVDV-2 strains using the PrimeFlow RNA assay [PDF]

, 2019
Bovine viral diarrhea viruses (BVDV), segregated in BVDV-1 and BVDV-2 species, lead to substantial economic losses to the cattle industry worldwide. It has been hypothesized that there could be differences in level of replication, pathogenesis and tissue

Mosaic BVDV vaccine induced BVDV-1 specific neutralizing antibodies.

, 2017
Serum neutralization assays were used to evaluate BVDV-1-specific neutralization titers at A) One-week post-boost; and B) one-week pre-challenge against five BVDV type 1 strains. Mean group titers are represented by the bars.

Pestivirus infection in cattle dairy farms: E2 glycoprotein ELISA reveals the presence of bovine viral diarrhea virus type 2 in northwestern Italy

BMC Veterinary Research, 2017
Background Bovine viral diarrhea virus (BVDV) types 1 and 2 are members of the Pestivirus genus of the Flaviviridae family. This genus also includes the HoBi-like virus, tentatively classified as BVDV type 3. BVDV-1 is widely distributed in Italy despite

Multi‐omics reveals gastrointestinal metabolic disorder‐induced diarrhea in postpartum dairy cows

iMetaOmics, EarlyView.
Nutritional diarrhea is a pervasive, costly challenge in dairy production. Using integrated metagenomic and metabolomic profiling, we identified coordinated microbial and metabolic alterations across the rumen, hindgut, and serum. In the rumen, enrichment of Prevotella sp.

Is Italy one of the countries with the highest genetic diversity of bovine viral diarrhea virus?

, 2014
Genetic typing of bovine viral diarrhea virus (BVDV) has distinguished BVDV-1 and BVDV-2 species and an emerging putative third species (HoBi-like virus), recently detected in southern Italy, representing the first report of cattle natural infection in ...

The consequences of host heterogeneity for parasite transmission depend on how host infectiousness is determined

Journal of Animal Ecology, EarlyView.
This study proposes two contrasting scenarios for how host infectiousness is determined: recipient dependence and donor dependence. These scenarios fundamentally alter how host heterogeneity shapes parasite transmission, demonstrating that the process by which infectiousness is determined is crucial for understanding the consequences of host ...
