Do antibiotics target peptidoglycan?

Antibiotics commonly target bacterial cell wall formation (of which peptidoglycan is an important component) because animal cells do not have cell walls. The peptidoglycan layer is important for cell wall structural integrity, being the outermost and primary component of the wall.

Why are some bacteria harder to treat with antibiotics than others considering peptidoglycan?

This also explains why penicillin and its derivative are more effective against Gram positive cells. With its peptidoglycan layer hidden beneath an outer lipid membrane it is harder for the penicillin to reach the peptidoglycan where it has activity whereas Gram positive cell walls leave the peptidoglycan exposed.
