Question

1.To study a clinical specimen in the lab, you must first introduce a sample of microorganism called the (culture/specimen/inoculum) to a nutrient medium.

2.Bacteria are typically most sensitive to antimicrobial drugs during which of the following growth phase(s). Select all that apply.

a. lag phase.

b. decline phase.

c. death phase

d. exponential growth phase.

e. log phase.

Answer 1

1. The answer is inoculum. The culture and specimens are different terminologies that do not involve small amount of microorganism.

Inoculum is the small amount of sample of microorganism that is added to a nutrient medium to study a clinical sample in lab.

2. Log phase is the growth phase of bacteria that is most susceptible to the action of the anti microbial drugs. It does get affected to some extent even in the exponential growth phase.

But the reason for its high susceptibility at log phase is the constant growth rate.
