Question

Streptomycin belongs to _______

• A. Penicillins
• B. Cephalosporins
• C. Aminoglycosides
• D. Macrolides

Hint:

Streptomycin, gentamicin, and amikacin are aminoglycoside antibiotics.

Answer 1

The Correct Option is C

To answer the question, we need to determine the category to which the antibiotic Streptomycin belongs. The options provided are:

• Penicillins
• Cephalosporins
• Aminoglycosides
• Macrolides

Let's examine each category:

1. Penicillins: These are a group of antibiotics that are derived from Penicillium fungi and are used to treat many bacterial infections. They are not related to Streptomycin.
2. Cephalosporins: These are a class of β-lactam antibiotics, which are similar to penicillins but with a broader spectrum of activity. Streptomycin is not classified under this category.
3. Aminoglycosides: This class of antibiotics includes drugs that are effective against aerobic gram-negative bacteria and are known to inhibit protein synthesis. Streptomycin is an aminoglycoside. It specifically binds to the 30S ribosomal subunit, causing a misreading of mRNA and inhibiting protein synthesis.
4. Macrolides: These are antibiotics that inhibit protein synthesis by binding to the 50S ribosomal subunit. Streptomycin is not a macrolide.

Therefore, based on the classification of antibiotics, Streptomycin belongs to the Aminoglycosides group.

The correct answer is:

• Aminoglycosides
