[Cultivation of Leptospira in a liquid culture medium with lysed rabbit blood]

A new method of the preparation of liquid culture medium for the cultivation of Leptospira has been developed on the basis of multiple freezing and thawing of defibrinated rabbit blood. A higher productivity of the new medium in comparison with the medium used in common practice has been established. The medium having a new composition is suitable for cultivation of Leptospira and the accumulation of biomass. The advantage of the medium made is in addition to high growth properties, the its economic efficiency and availability for practical laboratories.
