Figure 1. Superoxide anion release in response to M. abscessus.

M. abscessus (Mab; closed bar), or S. aureus (Sa; open bar) were added to neutrophils at a 10∶1 MOI, and superoxide release was compared to control neutrophils (hatched bars) by measuring reduction of cytochrome c after 60 min. Data is presented as mean±SEM; Bonferroni post-test indicated significant release of superoxide; n = 10, *p<0.05.
