Figure 4. Catalase activity is decreased with M. abscessus infection.

Figure 4

Differentiated THP-1 cells were uninfected (control), infected with M. abscessus (M. abs) or infected in the presence of MnTE-2-PyP (M. abs + MnTE-2-PyP) for 0, 24, 48 or 72 hours. A. A representative catalase activity gel. B. Densitometric analysis of catalase activity. Catalase activity was significantly reduced in infected cells as compared to non-infected cells at 72 hours post-infection. Catalase activity was decreased with infection at 24 and 48 hours post-infection (not significant). MnTE-2-PyP did not affect catalase activity. All data represent the mean ± SEM, n=4. The asterisk (*) denotes significant change from the respective control (p< 0.05).
