Isolating medium selective of vibrios cholera, a base of the mannose

摘要

The specification describes a selective isolation medium for cholera vibrio which comprises mannose, a sulfonphthalein colorant, polymyxin B, a surface active agent, and potassium tellurite. The above medium is excellent in both differentiability and in selectivity, and is particularly effective in detecting cholera bacteria from materials made available from environments or clinical inspection materials from patients on the way of the recovery, in which the number of cholera bacteria is small.
