Therapeutic efficacy of sophorolipid produced by R. babjevae YS3 (SL-YS3) on experimentally induced dermatophytosis in mice infected with T. mentagrophytes. (A) Macroscopic observation of the infected sites of the mice treated with 1 mg ml–1 (w/v) SL-YS3 and terbinafine (TRB) at the end of 21 days of treatment in comparison to the uninfected and infected, untreated control. (B) Culture recovery (%) of T. mentagrophytes from skin samples collected at different intervals of treatment period (0, 7, 14, 21 days) and cultured to determine the therapeutic efficacy in eradication of the fungus. Error bars represent standard deviation. Different letters indicate significantly different values as per ANOVA-LSD. (C) Histopathology of skin samples collected from sophorolipid (SL-YS3) and terbinafine (TRB) treated groups, stained with hematoxylin & eosin (H&E) and Periodic acid- Schiff (PAS) stains. SG, sweat glands; Ep, epidermis; HF, hair follicle; BV, blood vessel; CT, collagenase tissue; IC, inflammatory cells. Magnification = 10 ×, Scale bar = 100 μm.
