SEM analysis of M. abscessus and surface binding of Congo red. (A) SEM analysis of nontreated M. abscessus colonies. (B) M. abscessus colonies treated with Agelaia-12 (50 μM) showing aggregation and filamentous-like structures. (C) Data obtained from Congo red assay. M. abscessus treated with Agelaia-12 or polymyxin had increased retention of the dye (OD of supernatant) with inhibited growth (CFU count). The graph on the right represents the adjusted Congo red dye retention for each treatment.
