TrueFalse 1 The use of streptomycin is limited to grampositi

True/False:

(1) The use of streptomycin is limited to gram-positive bacteria as long as less hazardous drugs have been found ineffective.

Fill in the blank:

(2) Azoles mechanism of action interferes with the production of an essential component of the cell membrane called ____.

(3)

Solution

1)

Streptomycin is a broad-spectrum antibiotic, which is used to inhibit the bacterial protein synthesis, by altering the shape of 30S sub unit of ribosomes. As a result, mRNA loses its ability to read the sequence. It can inhibit growth of both Gram-negative and Gram-positive bacteria; hence the given statement is False.

2

Azoles mechanism of action interferes with the production of an essential component of the cell membrane called sterols or steroids.
