A number of hemolytic strains of treponemes were isolated from normal pigs and pigs which died of swine dysentery. According to their hemolytic pattern, these strains can be differentiated into strongly beta-hemolytic and weakly beta-hemolytic. According to Kinyon and Harris, aside from enteropathogenicity and hemolytic pattern, both fructose fermentation and indole production are the characteristics used in separating the two groups of treponemes. Our comparative study of these two groups of strains shows that while the fermentation activity is low for the strongly beta-hemolytic strains it is high for the weakly beta-hemolytic strains. The latter constitutes a heterogenous group which, contrary to Kinyon and Harris, can only be differentiated from the other strains by their ability to ferment lactose and to produce isovaleric acid in glucose supplemented broth.
从正常猪和死于猪痢疾的猪中分离出了许多溶血性密螺旋体菌株。根据它们的溶血模式，这些菌株可分为强β溶血和弱β溶血两类。根据金扬和哈里斯的研究，除了肠道致病性和溶血模式外，果糖发酵和吲哚产生也是区分这两组密螺旋体的特征。我们对这两组菌株的比较研究表明，强β溶血菌株的发酵活性较低，而弱β溶血菌株的发酵活性较高。与金扬和哈里斯的观点相反，后者构成了一个异质群体，只能通过它们在补充葡萄糖的肉汤中发酵乳糖和产生异戊酸的能力与其他菌株区分开来。
