Question

When would you use MTM medium rather than chocolate agar?

A) When isolating fastidious bacteria.
B) When testing antibiotic susceptibility.
C) When culturing anaerobic bacteria.
D) When performing serological tests.

Answer 1

MTM medium would be used rather than chocolate agar when culturing anaerobic bacteria because MTM medium creates an anaerobic environment, which is ideal for the growth of anaerobic bacteria.

Step-by-step explanation:

MTM medium would be used rather than chocolate agar when culturing anaerobic bacteria. This is because MTM medium is specifically designed to create an anaerobic environment, which is ideal for the growth of anaerobic bacteria. It contains reducing agents that help to remove oxygen from the medium and create a suitable environment for these bacteria to grow. On the other hand, chocolate agar is a general-purpose medium that supports the growth of a wide range of bacteria, including both aerobic and anaerobic bacteria.
