Various carbohydrates have been added to the fluid cultures of different strains of spirochetes in order to determine the behavior of the latter toward the carbohydrates. In the present experiment,… (More)
While a newly isolated bacterium would usually, as a mat ter of bionomic routine, be tested soon for its power of fermentation of various carbohydrates, nothing systematic has been done in this… (More)
The majority of the 76 new compounds possessed spirocheticidal powers ranging between 1: 1,000 (30) to 1:2,500 (14), while only 2 attained the power of 1:5,000, 1 of 1: 25,000, and 2 of 1: 50,000. On… (More)
Experiments were carried out for the study of culture spirochetes in their relation to various immunity reactions in vitro. Several strains of Treponema pallidum and one each of Treponema calligyrum,… (More)

In the foregoing experiments we attempted to determine whether or not, by subjecting several varieties of spirochetes to increasing doses of certain chemotherapeutic agents, a gradual increase of… (More)
