The development of spontaneous outbreak of hepatitis A (HA) among African green monkeys kept under strict isolation conditions was studied. It was shown that in the case of introduction of HAV the infection involved all the susceptible monkeys, running a course with and without any increase in the level of activity of serum alanine aminotransferase (ALT) After inoculation of commercial gamma-globulin only the infection without the ALT activity increase developed and some monkeys had no signs of HA at all. Experimental reinfection with HAV was produced in monkeys having anti-HAV titres of less than or equal to 1:3500.
对在严格隔离条件下饲养的非洲绿猴中甲型肝炎（HA）自然暴发的发展情况进行了研究。结果表明，在引入甲型肝炎病毒（HAV）的情况下，所有易感猴子都会被感染，感染过程中血清丙氨酸转氨酶（ALT）活性水平有的会升高，有的则不会升高。接种商业γ球蛋白后，只有ALT活性未升高的感染情况出现，而且一些猴子根本没有HA的迹象。对甲型肝炎病毒抗体滴度小于或等于1:3500的猴子进行了甲型肝炎病毒的实验性再感染。
