将来自 1094 个双歧杆菌菌株的可溶性细胞蛋白的聚丙烯酰胺凝胶电泳图谱与现有的 DNA-DNA 同源性数据以及这些菌株的表型和生化反应进行了比较。该属中 25 种不同的蛋白质模式和 24 个 DNA-DNA 同源组之间存在极好的相关性。基于共同表型特性的物种间分化通常是不可靠的。该物种以前被称为 B. eriksonii，是 B. dentium Scardovi 和 Crociani 的异名； Actinomyces parabifidis 是 B.infantis Reuter 的同义词； B. globosum（前 Scardovi、Trovatelli、Crociani 和 Sgorbati 1969）sp。十一月，名义。修订版（模式菌株，ATCC 25865）和 B.pseudolongum Mitsuoka 是密切相关但不同的实体；和 B. 细菌最小 sp。十一月（模式菌株，ATCC 27538）和枯草芽孢杆菌 sp。十一月（模式菌株，ATCC 27537）是有效物种。 B. coryneforme (前 Scardovi 和 Trovatelli 1969) sp.十一月，名义。修订版（模式菌株，ATCC 25911）是有效物种。介于婴儿双歧杆菌和长双歧杆菌之间的一组菌株，即婴儿双歧杆菌-长双歧杆菌，存在于小牛粪便中。具有 80% 或更高 DNA 同源性的菌株产生相同或几乎相同的蛋白质模式。
The polyacrylamide gel electrophoretic patterns of soluble cellular proteins from 1094 strains of bifidobacteria were compared with available DNA-DNA homology data and with the phenotypic and biochemical reactions of these strains. There was excellent correlation between the 25 distinct protein patterns and 24 DNA-DNA homology groups in the genus. Differentiation among species on the basis of common phenotypic properties often was unreliable. The species previously known as B. eriksonii is a synonym of B. dentium Scardovi and Crociani; that Actinomyces parabifidis is a synonym of B. infantis Reuter; that B. globosum (ex Scardovi, Trovatelli, Crociani and Sgorbati 1969) sp. nov., nom. rev. (type strain, ATCC 25865) and B. pseudolongum Mitsuoka are closely related but distinct entities; and that B. bacterium minimum sp. nov. (type strain, ATCC 27538) and B. subtile sp. nov. (type strain, ATCC 27537) are valid species. B. coryneforme (ex Scardovi and Trovatelli 1969) sp. nov., nom. rev. (type strain, ATCC 25911) is a valid species. A group of strains intermediate between B. infantis and B. longum, B. infantis-longum, occurs in calf feces. Identical or nearly identical protein patterns were produced by strains that had 80% or greater DNA homology.
