Equine Viral Arteritis
نویسندگان
چکیده
Equine viral arteritis (EVA) is a contagious viral disease of equids caused by equine arteritis virus (EAV), an RNA virus that is classified in the family Arteriviridae. The virus is found in horse populations in many countries worldwide. EVA cannot be differentiated clinically from a number of other respiratory and systemic equine diseases. While laboratory-confirmed outbreaks of EVA have been infrequently reported in the past, the incidence of the disease appears to be on the increase.

Equine Viral Arteritis: Essential Facts About the Disease
Although outbreaks are uncommon, equine viral arteritis is an important disease because of the potential risk of abortion in mares and establishment of the carrier state in a relatively high percentage of infected stallions. Equine arteritis virus carrier stallions constitute an important reservoir of infection, and appropriate precautions have to be taken when nonimmunized mares are inseminate...

The aim of the study was to present the usefulness of one tube reverse transcriptase polymerase chain reaction assay (RT-PCR) in comparison to virus isolation test (VI) in the detection of equine arteritis virus. The group of 82 semen samples taken from different stallions was examined. Equine arteritis virus was isolated in RK-13 cell monolayers from the seminal plasma of 11 animals. The same ...
متن کاملFolding and Oligomerization of the gp2b/gp3/gp4 Spike Proteins of Equine Arteritis Virus in Vitro
Equine arteritis virus (EAV) is a small, positive-stranded RNA virus. The glycoproteins gp2b, gp3 and gp4 form a heterotrimer in the viral envelope, which is required for cell entry of EAV. We describe expression of the ectodomains of the proteins in E. coli and their refolding from inclusion bodies. After extraction of inclusion bodies and dialysis, Gst-, but not His-tagged proteins, refold in...
متن کاملA longitudinal study of poor performance and subclinical respiratory viral activity in Standardbred trotters
INTRODUCTION While clinical respiratory disease is considered a main cause of poor performance in horses, the role of subclinical respiratory virus infections is less clear and needs further investigation. AIMS AND OBJECTIVES In this descriptive longitudinal study the relationship of markers of subclinical respiratory viral activity to occurrence of poor performance in racing Standardbred tro...
