The first isolation of equine arteritis virus in Argentina.

First isolation of equine rhinopneumonitis virus in Iran

Evaluation of neutralization patterns of the five unique Argentine equine arteritis virus field strains reported.

Equine viral arteritis (EVA) is a contagious viral disease that frequently causes mild or subclinical infections in adult horses. Only one EAV serotype has been described. However, there are differences in antigenicity, pathogenicity and neutralization characteristics of virus field strains. The interaction of two viral proteins, GP5 and M, is critical for infectivity and amino acid changes in ...

Rt-pcr as Effective Detection Method of Equine Arteritis Virus in the Semen of Naturally Infected Stallions

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 ...

The equine arteritis virus isolate from the 2010 Argentinian outbreak.

A semen sample from a stallion infected during the 2010 equine arteritis virus (EAV) outbreak was received for viral isolation prior to castration of the animal. The virus was identified using a polyclonal antibody immunofluorescence test. Reverse-transcription polymerase chain reaction (RT-PCR) was used to amplify a region of the GP5 gene with primers GL105F and GL673R. The PCR products were p...

Expression of M Protein from LP02/C Equine Arteritis Virus Inhibits Growth of Escherichia Coli M15-pQE30 System

Our objective was to obtain Equine Arteritis Virus M protein in prokaryotic system to test it as immunogen. LP02/C Equine Arteritis Virus cDNA was used as template to obtain and clone this protein. Equine Arteritis M protein was cloned in the expression vector pQE30 and the recombinant plasmid pQE30/M was transformed in Escherichia Coli M15 cells. The OD600 values of the IPTG-induced M15-pQE30/...
