OCCURRENCE OF NEUTRALIZING ANTIBODIES AGAINST BVDV-1 AND BVDV-2 IN CATTLE HERDS FROM MINAS GERAIS AND SÃO PAULO STATES, BRAZIL / Ocorrência de anticorpos neutralizantes contra o BVDV-1 e o BVDV-2 em rebanhos bovinos de Minas Gerais e São Paulo, Brasil.

Ars Veterinaria, 2011
A ocorrência de anticorpos neutralizantes contra os genótipos do vírus da diarréia viral bovina (BVDV-1 e BVDV-2) foi determinada pelo teste de virusneutralização (VN) em amostras de soro sangüíneo provenientes de 26 rebanhos bovinos não vacinados contra o BVDV, localizados nos Estados de Minas Gerais e São Paulo, Brasil.

Significant Impact of Schmallenberg Virus in Three Ruminant Farms: A Laboratory Experience

Veterinary Medicine International, Volume 2026, Issue 1, 2026.
Schmallenberg virus (SBV) is endemic in Europe and other parts of the world and represents an underestimated and underdiagnosed cause of abortion and economic losses for livestock farms. In the present study, we evaluated SBV’s impact on three ruminant farms, in particular, two dairy cattle farms with reproductive problems (including abortions ...

Landscape of exposure: Metapopulation dynamics and local environment structure pathogen exposure in desert bighorn sheep

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Dynamics of infectious disease in natural populations result from processes across scales, from host characteristics shaping exposure risk and susceptibility, to local environmental conditions driving vector populations, to the structure of metapopulation networks shaping transmission of pathogens across the landscape.

Risk of infection of dairy cattle in the EU with highly pathogenic avian influenza virus affecting dairy cows in the United States of America (H5N1, Eurasian lineage goose/Guangdong clade 2.3.4.4b. genotype B3.13)

EFSA Journal, Volume 23, Issue 12, December 2025.
Abstract This opinion assesses the risk of avian influenza H5N1 B3.13 genotype virus infection in EU dairy cattle. Introduction of the virus into EU dairy cattle, poultry or wild birds via trade or migratory birds from the US is assessed as highly unlikely.

A Focus on Natural Autophagy Modulators as Potential Host‐Directed Weapons Against Emerging and Re‐Emerging Viruses

Medicinal Research Reviews, Volume 45, Issue 6, Page 1850-1882, November 2025.
ABSTRACT Autophagy is a highly conserved intracellular process involved in maintaining homeostasis and in the degradation of damaged organelles and external pathogens. Nature provides complex and varied reservoirs of scaffolds and chemical entities that may have a pivotal role in the search for new therapeutic leads.

Clinical Approach and Successful Intervention of Congenital Hydrocephalus in Neonatal Calf

Veterinary Medicine and Science, Volume 11, Issue 6, November 2025.
A neonatal calf with congenital hydrocephalus, characterized by a dome‐shaped cranial vault, was treated with gradual drainage of cerebrospinal fluid and a horizontal mattress suture. The calf exhibited neurological improvement following surgery. At 12‐day follow‐up, normal behaviour and growth were observed with no neurological deficits.

Development and application of reverse transcriptase droplet digital PCR technology for sensitive detection of BVDV-1 and BTV in bovine semen

BMC Veterinary Research
Bovine viral diarrhoea virus genotype 1 (BVDV-1) and bluetongue virus (BTV) are potent viral pathogens that may be transmitted through semen, resulting in the spread of diseases via artificial insemination. Thus, establishing an early detection method for BVDV-1 and BTV infection is important for the trading of semen. In this study, we developed two RT‒

Expression and production of recombinant proteins from immunodominant E gene regions of bovine viral diarrhoea virus 1 (BVDV-1) Turkish field strains for prophylactic purpose

, 2017
Since the first description of Bovine Viral Diarrhoea Virus (BVDV) infection, many studies have been performed, and control and eradication programs were developed worldwide. Several studies have been conducted on the presence/prevalence and molecular characterization of BVD viruses in Turkey.
