Genetic Evolution of Mycobacterium abscessus Conferring Clarithromycin Resistance during Long-Term Antibiotic Therapy

Figure 1

Timeline of antibiotic usage and date of M. abscessus isolation. Triangle filled with white indicates that the strain was susceptible to clarithromycin at day 3, whereas yellow triangle represent clarithromycin resistance at day 3. All of the isolates were isolated from sputum.
