Treponema Mucosum (new Species), a Mucin-producing Spirochæta from Pyorrhea Alveolaris, Grown in Pure Culture

Pure Cultivation of Spirochæta Refringens

A strain of Spirochoeta refringens has been obtained in pure culture, and its morphological and cultural characteristics have been studied. The strain possessed no pathogenicity for rabbits or monkeys. It probably belongs to the genus Treponema, but it is easily differentiated from Treponema pallidum, Treponema microdentium, and Treponema macrodentium. Its relation to Spirochoeta balanitidis an...

The Influence of Carbohydrates on the Cultivation of Spirochetes

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, amygdalin, arabinose, beerwort, dextrin, galactose, glycogen, glucose, inulin, lactose, levulose, maltose, mannite, raffinose, saccharose, and starch were tested with seven strains of Treponema palli...

The Pure Cultivation of Spirochæta Duttoni, Spirochæta Kochi, Spirochæta Obermeieri, and Spirochæta Novyi

1. A method for the pure cultivation of Spirochoeta duttoni, Spirochoeta kochi, Spirochoeta obermeieri, and Spirochoeta novyi is described in this paper. In vitro these strains reach their maximum growth after seven, eight, or nine days at 37 degrees C. For their multiplication they require the presence of a piece of fresh sterile tissue and a body fluid capable of forming a loose fibrin with t...

Spirochæta Pallida (Spironema Pallidum) in Syphilis

Production of Fusaric Acid by Fusarium spp. in Pure Culture and in Solid Medium Co-Cultures.

The ability of fungi isolated from nails of patients suffering from onychomycosis to induce de novo production of bioactive compounds in co-culture was examined. Comparison between the metabolite profiles produced by Sarocladium strictum, by Fusarium oxysporum, and by these two species in co-culture revealed de novo induction of fusaric acid based on HRMS. Structure confirmation of this toxin, ...
