Haemophilus influenzae
Moraxella catarrhalis

Beta-lactamase production should not affect azithromycin activity.

“Other” microorganisms
Chlamydophila pneumoniae
Mycoplasma pneumoniae

The following in vitro data are available, but their clinical significance is unknown.

At least 90% of the following microorganisms exhibit an in vitro minimum inhibitory concentration (MIC) less than or equal to the azithromycin susceptible breakpoints of < 4 μg/mL. However, the safety and effectiveness of azithromycin in treating clinical infections due to these microorganisms have not been established in adequate and well-controlled trials.

Aerobic and facultative Gram-positive microorganisms

Streptococcus agalactiae
Streptococcus pyogenes
Streptococci (Groups C, F, G)
Viridans group streptococci

Aerobic and facultative Gram-negative microorganisms
