The EHV-1 viruses of fetal origin grew better and had a wider tissue culture host range than those isolated from horses with respiratory diseases. Comparisons of a fetal isolate (F/304) and a respiratory disease isolate (R/NM-3) in partly immune horses showed that the F/304 virus infected horses more readily, grew better in the nasopharynx, was more likely to cause abortion, and was excreted to a greater extent into the environment.
源自胎儿的马疱疹病毒1型（EHV-1）毒株比从患有呼吸道疾病的马匹中分离出的毒株生长得更好，并且具有更广泛的组织培养宿主范围。对部分免疫马匹中的一株胎儿分离株（F/304）和一株呼吸道疾病分离株（R/NM-3）进行比较，结果显示F/304病毒更容易感染马匹，在鼻咽部生长得更好，更有可能导致流产，并且在更大程度上排泄到环境中。
