Autoclaved liquid medium for propagation of Treponema hyodysenteriae

Three liquid media that differ slightly in composition but not in the method of preparation were developed for the propagation of Treponema hyodysenteriae and Treponema innocens. The three media are unique in that all components are sterilized by autoclaving before use. These media supported better growth of T. hyodysenteriae than did previously used liquid media.
