Which organism is typically treated with macrolides due to lack of cell wall?

Macrolides inhibit protein synthesis by binding the 50S ribosomal subunit, which is particularly effective for bacteria that lack a conventional cell wall. Mycoplasma pneumoniae has no peptidoglycan-containing cell wall, so cell-wall–targeting drugs like beta-lactams won’t work. That’s why a macrolide is the typical choice here. The other organisms have cell walls, so their standard effective therapies focus on disrupting cell wall synthesis rather than relying on a drug that targets protein synthesis.
