Epidemiology
- On average, 2 cases of nonpulmonary M. chelonae infection are reported in South Australia each year.[1]
Treatment
Antimicrobial Regimen
- 1. Localized infections [2]
- Preferred regimen: Clarithromycin 500 mg PO BID
- Alternative regimen: Azithromycin
- 2. Disseminated or extensive disease
- 2.1 monotherapy
- Preferred regimen: Clarithromycin 500 mg PO BID
