“…Así mismo, se han llevado a cabo estudios de prevalencia del virus herpes equino en países como Argentina (Galosi et al, 1998) La amplia distribución del VHE-1/ VHE-4 en la población de caballos del país podría deberse, en parte, al libre movimiento interno de caballos, ya que este virus no es restrictivo para el movimiento de los équidos en general. Además, se debe considerar el carácter subclínico de la enfermedad en caballos adultos (Goodman et al, 2012).…”

El objetivo del presente estudio fue determinar la seroprevalencia del virus Herpes Equino tipo 1 o Herpes Equino tipo 4 (VHE-1/VHE-4), causante de la rinoneumonitis viral en caballos. Se recolectaron muestras de suero (n=825) de caballos mayores a seis meses de edad, entre machos y hembras, identificados como caballos de crianza familiar, de carrera, Peruano de Paso y de equitación, clínicamente normales, provenientes de varias regiones del Perú, para la detección de anticuerpos neutralizantes contra el VHE-1/VHE- 4 mediante la prueba de neutralización viral. El 48.9 ± 5.3% (403/825) de las muestras tuvieron anticuerpos contra el VHE-1/VHE-4. Los títulos de anticuerpos tuvieron un rango entre 2 a >256, siendo de 58.6% de títulos de 2 a 8, de 29.5% en títulos de 16 a 64, y de 11.9% en títulos de 128 a >256. La prueba de regresión logística indicó que las variables sexo y lugar de procedencia no constituyeron factores de riesgo para la presentación de anticuerpos contra el VHE-1/VHE-4.

“…Thus, the existence of different strains or lineages of EHV-1 has been extensively investigated. EHV-1 strains were initially divided into different subgroups by the comparison of DNA fragment length after digestion of the genome with DNA restriction enzymes [46][47][48]. A study using 5 restriction enzymes conducted on isolates from 172 abortogenic and respiratory outbreaks in the US defined 16 strains of EHV-1 with significant differences in DNA fingerprint patterns.…”

Equine Herpes virus-1 (EHV-1) is one of the most common respiratory pathogens of the horse. EHV-1 induces several clinical signs of disease ranging in severity, from mild respiratory distress to abortion in pregnant mares, neonatal foal death and neuropathogenic disorders. This review details some aspects of EHV-1 biology, its life cycle and pathogenicity in the natural host. Protective immunity stimulated by natural EHV-1 infection, which is short lived and depends of both humoral and cellular immune responses, will also be treated here. Vaccination remains today one of the best options to fight EHV-1 infection and several different strategies of vaccination that have been investigated and developed over the past decades will be presented in this report.

Equine herpesvirus 1 (EHV-1) was first isolated in Argentina in 1979. This strain SPv has special restriction patterns, but a previous study demonstrated that SPv did not modify its growth in cell culture. In addition, it showed low virulence in the mouse respiratory model consistently with results found in female BALB/C at different state of gestation. This study evaluates in a mouse respiratory model, if primary infection with SPv strain protects animals from subsequent challenge with a pathogenic strain. Body weight loss was not observed in mice intranasally inoculated with SPv strain and challenged with HH1 Japanese strain. The SPv primary infection does not completely prevent clinical presentation by HH1 infection but the SPv inoculated animals recovered more quickly, with less intense and less persistent histological lesions. The challenge infection caused a rapid and prolonged increase in anti-EHV-1 antibodies in the mice previously infected with SPv, along with a more rapid reduction of viral titres in lungs. In this work it was demonstrated that this EHV-1 strain constitute a good immunogen. These results show that this SPv strain could be considered to produce an EHV-1 vaccine.
