Abstract

Sera of 157 baboons (Papio hamadryas and P. anubis) 21 chimpanzees (Pan troglodytes) five orang utans (Pongo pygmaeus) three mountain gorillas (Gorilla gorilla beringei) and three gibbons (Hylobates lar lar) were examined for the content of antistreptolysin O, antidesoxyribonuclease B, for the presence of rheumatoid factors as well as for the level and type of haptoglobin.

The mean antistreptolysin O titer (AST) in baboons was 106 ASU ± 18 in dextransulfate absorbed sera (“real” AST) and 182 ASU ± 34 in non-absorbed sera. The mean decrease after absorption was 20% (i.e., 20% inhibitor + 80% antistreptolysin O), a value that is lower than previously found in rhesus monkeys (55%) or in man (40%). Raised values of anti-DNase B were found in two baboons only, and none of the sera of that species displayed presence of rheumatoid factors.

In chimpanzees, the mean AST was 68 ± 29 in absorbed and 87 ASU ± 57 in non-absorbed sera. Anti-DNase B was raised in three animals, and in two cases the increase was correlated with raised AST. Of 19 chimpanzee sera examined, 13 were found to contain antigammaglobulins (“rheumatoid factors”) the titers of which reached 1:64 or more.

All primate sera tested so far showed haptoglobin type 1-1 or Hp 1-1-like patterns. The haptoglobin level in chimpanzees and baboons was comparable to that established in man; in rhesus monkey, on the other hand, much lower values (40–62 mg/100ml) or ahaptoglobinemia were observed. The sera of all monkeys and apes tested so far showed a very low (undiluted, or up to 1:10 titer at most) agglutinating activity against T4-antigencarrying streptococci. This is in agreement with our observations made previously which indicated that human or animal sera of haptoglobin type 1-1 agglutinated streptococci to a much lower degree than type Hp 2-2 or type Hp 2-1 sera.

类人猿和猴子的抗链球菌抗体、类风湿因子和触珠蛋白
对157只狒狒(Papio hamadryas和P. anubis)、21只黑猩猩(Pan troglodytes)、5只猩猩(Pongo pygmaeus)、3只山地大猩猩(Gorilla Gorilla beringei)和3只长臂猿(hyloates lar)的血清进行了抗溶血素O、抗脱氧核糖核酸酶B的含量、类风湿因子的存在以及触珠蛋白的水平和类型的检测。狒狒抗溶血素O效价(AST)在葡聚糖吸收血清(“真正的”AST)中为106 ASU±18,在非吸收血清中为182 ASU±34。吸收后的平均降幅为20%(即20%抑制剂+ 80%抗溶血素O),这一数值低于之前在恒河猴(55%)或人类(40%)中发现的数值。仅在两只狒狒中发现抗dna酶B值升高,并且该物种的血清均未显示类风湿因子的存在。在黑猩猩中,吸收血清的平均AST为68±29,非吸收血清的平均AST为87±57。三种动物的抗- dnase B升高,其中两种的升高与AST升高有关。在19种黑猩猩的血清中,13种被发现含有抗- γ球蛋白(“类风湿因子”),其滴度达到1:64或更高。迄今为止测试的所有灵长类动物血清均显示1-1型触珠蛋白或Hp -1样模式。黑猩猩和狒狒的触珠蛋白水平与人类的水平相当;另一方面,在恒河猴中,观察到低得多的值(40-62 mg/100ml)或血红蛋白血症。迄今为止测试的所有猴子和猿的血清显示对携带t4抗原的链球菌的凝集活性非常低(未稀释,或最多达1:10滴度)。这与我们之前的观察结果一致,即人类或动物血清中1-1型接触珠蛋白凝集链球菌的程度远低于Hp -2型或Hp -2型血清。
