BSK-H medium is a high quality nutrient liquid for the reliable cultivation of Borrelia sp.

• Rich medium for the cultivation of all Borrelia species and spirochetes
• Only small number of initial organism is needed to start a culture
• Ready to use medium (complete)

BSK-H medium is a quite complex formulation with an extraordinary high content of proteins and peptides. It is especially rich in nucleosides, glucose as energy source and contains high concentrations of vitamins. BSK-H medium can be widely used for the cultivation of spirochetes, especially for Borrelia burgdorferi and Borrelia hermsii. Only small amounts of organisms are sufficient for the inoculation. However, the values found in the literature, as well as personal communications are varying too much, so that no general recommendation for the inoculum number can be given. The generation time lies between 11 and 18 hours, so that in 7 to 9 days 0,5 to 4,0×10⁸ cells/ml can be obtained.
