Serologic testing revealed that 17/84 (20.2%) of bought-in Aotus and 1/31 (3.2%) of colony-born Aotus had haemagglutination-inhibition antibody. Clinically-inapparent measles infections were detected in 3 monkeys by increased antibody titres. Following the detection of a recent infection, antibody titre persisted at a high level for at least 240 days. Although 84% of the monkeys were sero-susceptible, no further serological evidence of measles infection occurred.
血清学检测显示，购入的夜猴中有17/84（20.2%）以及圈养出生的夜猴中有1/31（3.2%）具有血凝抑制抗体。通过抗体滴度升高在3只猴子中检测到了无症状麻疹感染。在检测到近期感染后，抗体滴度至少在高水平持续了240天。尽管84%的猴子血清学易感，但未出现麻疹感染的进一步血清学证据。
