Question

Which of the following is NOT a characteristic of transport media?
Options
A They are designed to prevent drying (desiccation) of the specimen
B They include growth factors to enhance microbial growth
Correct Answer
C They may contain antibiotics and glycerol for tissue culture specimens
D They inhibit the overgrowth of unwanted bacteria
Correct Answer

Option B is the correct answer.

Detailed Explanation

Transport media are designed to maintain the viability of microorganisms during transit without promoting their significant multiplication or overgrowth. Including growth factors to enhance microbial growth would defeat this purpose and could lead to changes in the original sample composition. They typically contain buffers and sometimes selective agents or charcoal to preserve the sample as close to its original state as possible.

Hint

Remember the primary goal of transport media is preservation and stability of the sample, not proliferation.
