A subinhibitory concentration of clarithromycin inhibits Mycobacterium avium biofilm formation

Antimicrob Agents Chemother. 2004 Dec;48(12):4907-10. doi: 10.1128/AAC.48.12.4907-4910.2004.

Abstract

Mycobacterium avium causes disseminated infection in immunosuppressed individuals and lung infection in patients with chronic lung diseases. M. avium forms biofilm in the environment and possibly in human airways. Antibiotics with activity against the bacterium could inhibit biofilm formation. Clarithromycin inhibits biofilm formation but has no activity against established biofilm.
