“…The original cultures were made on horse blood agar plates and incubated anaerobically in a McIutosh and Ffldes jar for 16 hours (6,8). Any hemolytic colonies were fished and the cultures purified by plating.…”

“…It is thus clear that the vast majority of strains from severe puerperal infections due to hemolytic streptococci are members of Group A, and that most of those which are saprophytic in the birth canal either before or after delivery, as well as those strains isolated from women with minor degrees of fever, do not belong to Group A. Hare and Colebrook (6) were able to differentiate by means of biochemical tests the majority of these saprophytic strains (those placed in Groups B and D in this paper) from the strains isolated from infections. The present work confirms their findings in this respect.…”

1. The majority of strains of hemolytic streptococci from puerperal infections of the uterus were identified serologically as members of the Group A described by Lancefield. 2. The majority of strains isolated from the birth canal of women whose puerperium was afebrile were not members of Group A. 3. The existence of two new serological groups of hemolytic streptococci, Groups F and G, is described.

270. Lancefield group B streptococci (Str. agalactiae) on the hands of milkers and others

Lancefield Group B streptococci have been recovered from the hands of milkers even in herds where infection was very light. Since these organisms had the biochemical reactions of Str. agalactiae, and since none were recovered from the hands of non-milkers, it is considered that they were identical with this organism and that the milkers' hands are a potential source of danger to cows. The methods of disinfection at present in use have been criticized and suggestions for improvements made.

“…Tillet and Garner (1933) found that strains of haemolytic streptococci derived from human infections had the property of digesting clotted human fibrin, while most strains derived from animal sources failed to do so. Hare and Colebrook (1934), applying this test to strains of saprophytic haemolytic streptococci isolated from the vagina of afebrile parturient women, reported that the majority of such strains caused no fibrinolysis. We submitted twelve of the strains isolated from normal throats to this test.…”

1. In Hong Kong, where scarlet fever is extremely rare, the Dick reactions of a random sample of 921 Chinese were ascertained. Positive reactions were obtained in 19·1 per cent. The distribution of positive reactors in different age groups is recorded; it bears a general similarity to those recorded by various observers in Europe and the U.S.A.2. A haemolytic streptococcal carrier rate of 6·6 per cent, was determined by nasopharyngeal swabbing of 1600 Hong Kong Chinese. The frequency of haemolytic streptococci was higher during the cooler months of the year and among the younger age groups.3. Erythrogenic toxin production and fibrinolytic activity were demonstrated in a number of the strains of streptococci isolated from apparently normal throats.4. The significance of these findings is discussed.
