“…The single salicinlactose + Group B culture of human origin was isolated from urine. The only previous record of such cultures from human sources is that of Plummer (1934) who found salicin -lactose+ strains which were later identified as Group B (Brown, 1939) in the throats of six children. It is as yet uncertain whether or not these subdivisions represent separate species within Group B.…”

This study was undertaken, first, to determine the prevalence of the different serologic groups of hemolytic streptococci in specimens collected in this vicinity; and, second, to obtain additional data on the correlation between certain biochemical tests and the group precipitin reaction of Lancefield (1933). A total of 561 cultures was studied of which 188 were isolated from material from human infections, 53 from normal persons, 8 from infected animals, and 312 from raw milk. Several such studies have been made since the Lancefield technic has been available. A similar survey of cultures from human and animal sources was reported by Coffey (1938). Butler (1938), Plummer (1935), Reid and Browne (1939) and Kobayashi (1939) have studied cultures derived chiefly from a variety of human sources. Among others who have classified hemolytic streptococci by the precipitin test are: Hare (1935), Davis and Guzdar (1936), Foote, Welch, West and Borman (1936), and Kodama, Ozaki, Nishiyama and Chiku (1938), who studied cultures from the nose and throat; Hare and Maxted (1935) and Smith and Sherman (1938), who examined human feces; Lancefield and Hare (1935), Rolfs, Trussell and Plass (1938), and Congdon (1935), who collected strains from the vagina and respiratory tract of parturient women; Colebrook, Maxted and Johns (1935), whose cultures were secured from human skin; and Plastridge and Hartsell (1937), Valentine (1938),

“…Following the Holman (1916) classification, in which the differentiation of Streptococcus pyogenes from Streptococcus equi rests entirely on the fermentation of lactose, many workers have reported as "Streptococcus equi" cultures of hemolytic streptococci from human sources, which did not ferment lactose. Evans (1936c) examined a number of such lactose-negative cultures obtained from Coburn and Pauli (1932), Fisher (1933) and Plummer (1934), and found that all of them could be readily differentiated from Streptococcus equi on the basis of their actions on human fibrin and trehalose. On the basis of the fermentation tests alone, the organism which could be most readily confused with Streptococcus equi is the "minute hemolytic streptococcus" of .…”

“…All strains share a common cell wall carbohydrate antigen and are designated Lancefield group B streptococci. Early reports suggested that strains causing human infections were opportunistic and of bovine origin (Hare & Colebrook 1934;Plummer 1934). There is no definitive evidence, however, to suggest that bovine strains necessarily cause human infections and vice versa.…”

Group B streptococci (Streptococcus agalactiae) from humans and animals were compared for cultural, biochemical, serological and bacteriocin sensitivity properties. Each isolate possessed the group B carbohydrate antigen, hydrolysed hippurate, and was CAMP test positive. Most human isolates were characterized as bacitracin resistant, pigment producing, haemolytic, and salicin but not lactose utilizing. In contrast bovine isolates were usually bacitracin sensitive, non-pigment producing, non-haemolytic, salicin and lactose utilizing. Isolates from other animals behaved similarly to those from humans. Whereas human isolates belonged to a variety of serotypes and were uniformly sensitive to bacteriocins, bovine isolates showed varying sensitivity to bacteriocins and most belonged to serotype II or were non-typable. We believe these results support the belief that Strep. agalactiae from humans and cattle are separate populations sharing the same group B carbohydrate antigen.
