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 may contain antibiotics and glycerol for tissue culture specimens
C They contain buffers and salts such as carbohydrates, peptones, and other nutrients
D They include growth factors to enhance microbial growth
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Transport media are designed to maintain the viability of microorganisms without allowing their multiplication, thus preserving the original relative numbers of different microbes. Including growth factors to enhance microbial growth would defeat this purpose by encouraging some microbes to overgrow others.

Hint

What is the primary goal of transport media during sample collection and delivery to the lab? Is it to grow microbes, or to maintain them as they are?
