The first antibiotic discovered was

Most of the available antimicrobial agents are effective against

Which of the following does not target the same bacterial component as the others?

Which of these antibiotics has the fewest side effects?

Which of the following methods of action would be bacteriostatic?

Which of the following antimicrobial agents is recommended for use against fungal infections?

More than half of our antibiotics are

Which of the following drugs is not used primarily to treat tuberculosis?

Which of the following organisms would most probably be sensitive to natural penicillin?

Streptomyces bacteria produce all of the following antibiotics except

Broad-spectrum antibiotics

A bacteriostatic antibiotic

The difference between penicillin and ampicillin is

β-Lactamase is

All of the following are targets for antibiotics except

Monobactam antibiotics have

Protein synthesis is

All of the following target the bacterial ribosome except

The first target of sulpha drugs in bacteria is ____ synthesis

Antiviral drugs


All of the following are antifungal drugs except

Which of the following is used in treating protozoan infections?

The activity of penicillin is most effective during cell growth because penicillin prevents the cross-linking of the NAG and NAM units and thereby prevents the formation of an intact cell wall.

Isoniazid is very effective against mycobacteria because it inhibits the synthesis of protein.

The plasma membrane in bacteria is a prime target for antibiotics because any disruption of this membrane will destroy the bacteria’s ability to survive.

The synthetic forms of erythromycin known as azithromycin and clarithromycin have expanded spectra and are used for respiratory infections because they are more potent.

Rifampin is used only in combination therapy because resistance develops rapidly if the antibiotic is used alone.

Which of the following antibiotics destroys red blood cells as its mechanism of action?

Which of the following antibiotics inhibits the production of sterols as its mechanism of action?

Inhibition of microtubule formation is the mechanism of action for which of the following antibiotics?

Which of the following antibiotics interferes with nucleic acid synthesis as its mechanism of action?
