The foal is born without detectable antibody and except for small amounts of IgM is devoid of immunoglobulins. Intrafetal administration of either Venezuelan equine encephalomyelitis virus (VEE-TC83) or ovine erythrocytes elicited IgGa, IgGb and a trace of IgG(T). The fetal blood VEE-TC83 neutralization titre was higher than the neutralization titre elicited by the same preparation in older horses.
新生马驹出生时无可检测到的抗体，除少量IgM外，缺乏免疫球蛋白。给胎儿体内注射委内瑞拉马脑炎病毒（VEE-TC83）或绵羊红细胞可诱导产生IgGa、IgGb和微量IgG(T)。胎儿血液中VEE-TC83中和滴度高于相同制剂在成年马中诱导产生的中和滴度。
