Method logic
Infusion from beef heart, proteose peptone and L-cystine provide nitrogen, vitamins and amino acids. Dextrose is a carbon source.Sodium chloride maintains the osmotic balance of the medium and agar is the solidifying agent. The introduction of a 2% hemogobinsolution makes the medium suitable for cultivating Francisella tularensis.
