Azithromycin has relatively broad but shallow antibacterial activity. It inhibits some Gram-positive bacteria, some Gram-negative bacteria, and many atypical bacteria.
A strain of gonorrhea reported to be highly resistant to azithromycin was found in the population in 2015. Neisseria gonorrhoeae is normally susceptible to azithromycin, but the drug is not widely used as monotherapy due to a low barrier to resistance development.Extensive use of azithromycin has resulted in growing Streptococcus pneumoniae resistance.
