Microbial Chemotherapy Lecture Quiz

Amoxicillin is an example of a penicillin with a narrow spectrum of activity.

Penicillins inhibit the formation of the cell membrane of bacteria.

Amoxicillin is primarily excreted through the liver.

Aminoglycosides like gentamicin are non-polar compounds.

Gentamicin is commonly used to treat fungal infections.

Resistance to penicillins can occur due to the breaking of the amino sugar ring by bacteria.

Streptomycin irreversibly inhibits protein synthesis.

Streptomycin can easily pass through cell membranes due to its high polarity.

Nephrotoxicity caused by streptomycin is irreversible.

Minocycline exerts its action through irreversible inhibition of protein synthesis.

Tetracyclines, including minocycline, are not affected by food or metal ions during metabolism.

Minocycline is contraindicated in children and pregnant women.

Amoxicillin is derived from Penicillium chrysogenum.

Gentamicin is a non-polar compound.

Resistance to penicillins can occur due to the breaking of the beta-lactam ring by bacteria.

Minocycline's action is through irreversible inhibition of protein synthesis.

Amoxicillin has a broad spectrum of activity.

Streptomycin can easily pass through cell membranes due to its high polarity.

Streptomycin is absorbed when given parenterally due to its low polarity allowing for passage across membranes.

Minocycline exerts its bacteriostatic action through reversible inhibition of protein synthesis.

Streptomycin is primarily metabolized in the liver and eliminated unchanged through bile.

Tetracyclines, including minocycline, are affected by food and metal ions during absorption and distribution.

Photosensitivity is a common adverse effect associated with minocycline administration.

Nephrotoxicity caused by streptomycin is irreversible even after discontinuation of the drug.
