- Aerobic and facultative gram-negative microorganisms: Haemophilus ducreyi, Haemophilus influenzae, Moraxella catarrhalis, Neisseria gonorrhoeae.
- Other microorganisms: Chlamydia pneumoniae, Chlamydia trachomatis, Mycoplasma pneumoniae, and Beta-lactamase production should not affect azithromycin activity.
- Aerobic and facultative gram-positive microorganisms: Streptococci (Groups C, F, G), Viridans group streptococci.
- Aerobic and facultative gram-negative microorganisms: Bordetella pertussis, Legionella pneumophila.
- Anaerobic microorganisms: Peptostreptococcus species, Prevotella bivia.
