Erythromycin is an antibiotic in the macrolide class. It is derived from the bacterium Streptomyces erythreus and inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit. This action effectively prevents the growth and reproduction of bacteria. 

Employed as a selective agent in culture media to isolate bacteria that are sensitive to this antibiotic. Erythromycin is effective against a broad spectrum of bacteria, including Gram-positive bacteria (such as Streptococcus, Staphylococcus, and Corynebacterium species) and some Gram-negative bacteria (such as Haemophilus influenzae and Neisseria gonorrhoeae).
