Principle And Interpretation
This is diphasic medium developed for the transport of the primary cultures of cerebrospinal fluids from patients with bacterial meningitis. It contains nutrients such as charcoal, starch, and gelatin which support the growth of fastidious organisms like N. meningitidis, S. pneumoniae, H. influenzae. Activated charcoal and starch neutralizes different inhibitory substances acting as detoxifying agents. Gelatin in the medium preserves bacteria by forming a protective coat on the cell surface.
Type of specimen
Clinical samples : cerebrospinal fluid
