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

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

Virology, 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 tropism between BVDV-1 and BVDV-2 strains.

Serosurvey of Bovine Viral Diarrhea Virus in Cattle in Southern Japan and Estimation of Its Transmissibility by Transient Infection in Nonvaccinated Cattle

Viruses
Bovine viral diarrhea (BVD) is caused by the BVD virus (BVDV) and has been reported worldwide in cattle. To estimate BVDV circulation among cattle where few BVD cases were reported in southern Japan, 1910 serum samples collected from 35 cattle farms ...

Increased genetic variation of bovine viral diarrhea virus in dairy cattle in Poland

BMC Veterinary Research, 2019
Background Bovine viral diarrhea virus (BVDV) causes severe economic losses and is one of the most important viral pathogens of ruminants worldwide. The infection manifests itself in a variety of clinical symptoms.

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 ...

Circulation of bovine viral diarrhea virus – 1 (BVDV-1) in dairy cattle and buffalo farms in Ismailia Province, Egypt

The Journal of Infection in Developing Countries, 2015
Introduction: Bovine viral diarrhea (BVD) is one of the most economically significant diseases in the bovine industry causing losses due to diarrhea, reproductive disorders, immunosuppression and mortalities. The aim of our investigation was to detect and subtype BVDV from calves on two dairy cattle and two buffalo farms in Ismailia province, Egypt as ...

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.

Molecular Characterization of a Novel Bovine Viral Diarrhea Virus Isolate SD-15.

PLoS ONE, 2016
As one of the major pathogens, bovine viral diarrhea virus caused a significant economic loss to the livestock industry worldwide. Although BVDV infections have increasingly been reported in China in recent years, the molecular aspects of those BVDV ...
