The area where occurred the abortion or childbirth sick foal should be cordoned off and isolated to prevent access of other pregnant mares to the area, and should be thoroughly disinfected. Fluorescent antibody test can be performed on frozen sections of liver and lung. The family Herpesviridae is divided into three subfamilies: Alphaherpesvirinae, Betaherpesvirinae and Gammaherpesvirinae, where EHV-5 together with EHV-2 and EHV-7 (also called asinine herpes virus 2 ) are classified as equine gammaherpesviruses . Testing of horses without a history of exposure or without clinical signs is not recommended. According to the Kentucky State Veterinarian’s website, as of September 11, 2012, 10 WNV-positive horses were reported from nine counties.

If passed, both bills would have required the labeling of all foods containing ingredients from genetically modified crops. It is not clear whether myonecrosis is a direct toxic effect of S equi on muscle cells or is due to profound nonspecific T-cell stimulation by streptococcal superantigens and the release of high levels of inflammatory cytokines.

However, all the isolates examined in our study had conserved gene arrangements, with only one SNP detected in UL44 (a non-synonymous substitution), and the predicted restriction endonuclease cleavage patterns generated from the sequence data varied mainly as a result of variations in short tandem repeat iterations. The source of infectious droplets is most often respiratory secretions. Based on the Bam HI fingerprints the commonest virus identified in our study was EHV1.IP (P is for prototype strain).
