- 在實驗室動物中：
  - 兔子是最易感，接種部位會出現強烈的局部搔癢。
  - 天竺鼠的易感性較低，可能抵抗皮下注射，但會在腦內或腹腔內注射後死亡。

Pigs are the only natural host for PRV, but the virus can naturally infect cattle, sheep, cats, dogs, mice, and rats,
causing fatal disease. Dogs seem to be highly susceptible, and there are numerous reports of PRV infection of dogs, particularly hunting dogs, either due to consuming raw meat or by direct contact with PRV‐infected swine. Infections have also been reported in brown bear, black bear, Florida panther, raccoon, coyote, deer, and farm fur animal species (mink and foxes). Only swine (Suidae) are able to survive a productive PRV infection. The susceptibility of other members of the artiodactyl suborder Suina, for example, Tayassuidae (peccaries) and possibly hippopotamuses, has not been established. Therefore, reports of low PRV seroprevalence (<1%) in free‐ranging peccaries in the southwestern United States should be interpreted with caution.

Of the laboratory species, the rabbit is the most susceptible and develops intense local pruritus at the inoculation site. Guinea pigs are less susceptible and may resist subcutaneous inoculation, but succumb to intracerebral or intraperitoneal inoculation.
