Abstract
Los Herpesvirus Equino tipo 1 (VHE-1) y Herpesvirus Equino tipo 4 (VHE-4) son patógenos que están ampliamente distribuidos en las poblaciones de equinos de todo el mundo, considerándose dentro de los agentes más importantes debido a las consecuencias devastadoras que producen a la industria equina. Las enfermedades producidas por estos virus se denominan comúnmente como Rinoneumonitis Equina (RNE) ya que ambos tienen la capacidad de producir enfermedad respiratoria, sin embargo, el VHE-1 también puede causar abortos en los últimos meses de gestación, muerte en neonatos o disfunción neurológica; por otra parte, el VHE-4 raramente puede ocasionar abortos. Luego de la infección primaria por VHE-1 o VHE-4, estos tienden a entrar en un estado de latencia viral, en la cual los animales infectados se encuentran aparentemente sanos, pudiendo posteriormente reactivarse frente a situaciones de estrés. Dichos mecanismos permiten la supervivencia y propagación de estos virus a otros caballos susceptibles. VHE-1 y VHE-4 son enzoóticos en muchos países del mundo, en especial en los que se mantienen grandes poblaciones de caballos, por lo que es primordial realizar un diagnóstico oportuno y certero, además de conocer las estrategias de prevención y control que existen a escala mundial y nacional. La presente revisión bibliográfica busca otorgar información actualizada referente a la infección por VHE-1 y VHE-4 y dar a conocer la importancia de la prevención de la infección por estos patógenos
Equine Herpesvirus type 1 (EHV-1) and Equine Herpesvirus type 4 (EHV-4) are pathogens that are widely distributed in equine populations around the world, being considered among the most important agents due to the devastating consequences they produce to the equine industry. Diseases caused by these viruses are commonly referred to as Equine Rhinoneumonitis (ERN) as both have the capacity to produce respiratory disease, however, EHV-1 can also cause miscarriages in late gestation, neonatal death or neurological dysfunction; on the other hand, EHV-4 can rarely cause miscarriages. After primary infection with EHV-1 or EHV-4, they tend to enter into a viral latency state in which the infected animals are apparently healthy and can subsequently be reactivated in the event of stress. These mechanisms allow the survival and propagation of these viruses to other susceptible horses. EHV-1 and EHV-4 are enzootic in many countries of the world, especially in which that have large populations of horses, so it is essential to make a timely and accurate diagnosis, as well as to know the strategies of prevention and control that exist at the global and national levels. The present literature review aims to provide updated information regarding infection by EHV-1 and HEV-4 and to inform the importance of prevention of infection by these pathogens
