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 ...

Key insights into biosecurity risks, communication preferences and behaviour change drivers among livestock transporters in Australia

Australian Veterinary Journal, EarlyView.
The transportation of livestock poses an increased risk of disease transmission, with transportation vehicles acting as vectors for disease. Biosecurity management within the livestock industry is therefore critical to reduce the risk of disease transmission. This study investigated the current biosecurity practices of stakeholders within the livestock

Bovine viral diarrhea virus NS4B protein is an integral membrane protein associated with Golgi markers and rearranged host membranes

Virology Journal, 2009
Background Very little is known about BVDV NS4B, a protein of approximately 38 kDa. However, a missense mutation in NS4B has been implicated in changing BVDV from a cytopathic to noncytopathic virus, suggesting that NS4B might play a role in BVDV ...

BVDV Npro protein mediates the BVDV induced immunosuppression through interaction with cellular S100A9 protein

Microbial Pathogenesis, 2018
The innate immune response is a vital part of the body's antiviral defense system. The innate immune response is initiated by various receptor interactions, including danger associated molecular patterns (DAMPs). The S100A9 is a member of the DAMPs protein family and, is released by activated phagocytic cells such as neutrophils, monocytes, macrophages

Seroprevalence and Presumed Bovine Leukaemia Virus and Coxiella burnetii Coinfections in Three Dairy Cattle Herds From the Al Ain Region, United Arab Emirates

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
ABSTRACT Background Bovine leukaemia virus (BLV) and Coxiella burnetii are important infectious pathogens of dairy cattle with potential implications for animal health, productivity and zoonotic transmission (in the case of C. burnetii). Because BLV may alter immune function, we hypothesize that infection with the virus could increase cattle ...

Dual natural infection with bovine viral diarrhea virus -1 and -2 in a stillborn calf: tissue distribution and molecular characterization [PDF]

Open Veterinary Journal, 2018
Dual infections with both bovine viral diarrhea virus (BVDV)-1 and -2 seem to be unusual. The aim of this study was to describe an infection with both BVDV genotypes in a stillborn calf.

CRISPR-Cas13a-Based Detection for Bovine Viral Diarrhea Virus

Frontiers in Veterinary Science, 2021
Bovine Viral Diarrhea Virus (BVDV) is the main pathogen of bovine viral diarrhea disease (BVD), which leads to enormous economic losses in the cattle industry. A sensitive and specific detection for BVDV is advantageous to the control of BVDV.

Bovine bacterial abortion caused by Escherichia coli infection

Veterinary Record Case Reports, Volume 14, Issue 3, August 2026.
Abstract A 3‐year‐old, 500 kg Holstein cow aborted at 7 months of gestation. On histological evaluation of the fetal lungs, abundant neutrophils infiltrated the alveolar spaces, bronchi and bronchioles with intralesional Gram‐negative bacteria, immunolabelled with Escherichia coli immunohistochemistry.

Identification and Optimization of a Truncated Hs‐1‐Derived Antimicrobial Peptide for Enhanced Broad‐Spectrum Antiviral Activity

ChemMedChem, Volume 21, Issue 13, 14 July 2026.
Can a shorter peptide be a better antiviral? Structure‐guided optimization of the amphibian peptide Hs‐1 reveals a minimal α‐helical core that, after terminal modification, displays enhanced stability and submicromolar broad‐spectrum activity against enveloped viruses while maintaining a favorable safety profile. Antimicrobial peptides (AMPs) represent
