This is because it is a selective antibiotic that, when entering the body, binds to the 50s subunit of bacterial ribosomes, thus causing the disruption of protein transcription of bacteria.

Explanation:

This is because it is a selective antibiotic that, when entering the body, binds to the 50s subunit of bacterial ribosomes, thus causing the disruption of protein transcription of bacteria.

This drug does not stop the transcription of human proteins since bacteria and humans do not have the same ribosomes, therefore humans or host cells do not have the active site to which the drug binds.

Erythromycin falls into the macrolide family and is considered a drug that is bacteriostatic at low concentrations and bactericidal at very high concentrations.

The difference between these named terms is that one ends the life of the bacterium (bactericidal) and the other stops the bacterial metabolism preventing its possibility of increasing in number.
