Background: Currently, there is a trend towards using natural and ethnopharmacological species with therapeutic potential. This investigation evaluated the antifungal activity of two species in the Ecuadorian Andes, which are used in treating dermatomycosis: Ambrosia arborescens Mill. (Marco) and Aristeguietia glutinosa Lam. (Matico). Methods: We worked with seven concentrations (100 to 700ppm) of Ambrosia arborescens Mill. extract and ten concentrations (0.5 to 5%) of essential oil (EO) of Aristeguietia glutinosa Lam. on Trichophyton mentagrophytes ATCC 9533, Trichophyton rubrum ATCC 28188, Microsporum canis ATCC 36299 and Candida albicans ATCC 10231. The methodology used was a modified version of the Kirby-Bauer method, using diffusion in agar wells. Results: The Tukey test, after the one-way Anova, determined effective concentrations of EO: 5% for Trichophyton mentagrophytes, 4.5% for Trichophyton rubrum, 5% for Microsporum canis and 2% for Candida albicans. In the extracts, the concentration of 700ppm was used for Trichophyton mentagrophytes, Trichophyton rubrum, and 600ppm for Microsporum canis and Candida albicans. Conclusions: The evaluation of the antifungal activity of the Ambrosia arborescens extract showed inhibition in the studied dermatophytes in each one of the planted concentrations (100 to 700ppm). The evaluation of the antifungal activity of Aristeguietia glutinosa EO showed inhibition in the studied dermatophytes in each of the planted concentrations (0.5 to 5%).

Tribal people use the flower extract of <em>Caesalpinia pulcherrima<strong> </strong></em>to cure liver, stomach and skin disorders in Indian traditional medicine. This study aimed to evaluate the protective roles of purified quercetin extracted from suspension culture of <em>C. pulcherrima</em> against selected bacterial and fungal pathogens. A simple protocol was developed for callus production using leaf explants<em>.</em> 2, 4-D (2.5 mg/l), BAP (2.5 mg/l) + kin (1 mg/ml) was effective for optimal callus induction. Subsequently, cell suspension culture was established.  Role of effect of elicitors in cell suspension culture was carried. Sucrose, ABA and salicylic acid (SA) at different concentrations influenced cell biomass and quercetin accumulation. Cells cultured in the medium fortified with 45 g/L sucrose without ABA/SA showed the highest quercetin content (16.5 mg/g). Flavonoids was purified, fractionated by HPLC-DAD followed by NMR revealed the presence of quercetin, isoquercetin, quercetrin, rutin, quercetin 3-O-β-D-xyloside, quercetin 3-Oarabinopyranoside, quercetin 3-O- α-arabinopyranosyl (1→2) β-galactopyranoside,  isorhamnetin 3-O-rutinoside and an unknown compound. Subsequently, anthocyanin was evaluated for antimicrobial activity against selected Gram-positive bacteria (<em>S. aureus, Bacillus subtilis</em>, and <em>Enterococcus faecalis</em><em>)</em>, Gram-negative bacteria (<em>E. coli, </em>and <em>Pseudomonas aeruginosa</em>) and fungi such as <em>Aspergillus flavus, Candida albicans </em>and <em>Trichophyton rubrum</em>. Quercetin was found to be active against four bacteria and the fungi- <em>Candida albicans</em>. The highest inhibitory effects were found on <em>S. aureus</em> and <em>Enterococcus faecalis</em>. Gram negative bacteria showed more resistance i.e., with insignificant MIC and MBC values. Among the fungi, <em>Aspergillus flavus</em> and <em>Trichophyton rubrum</em> displayed remarkable MIC and MKC values. These results suggest that quercetin may be used as a natural antimicrobial agent. Future works are designed to trace the molecular mechanism of antimicrobial potentiality of quercetin against these tested pathogens

Background Onychomycosis is the most common infectious nail disorder. Direct mycologic examination is still the cornerstone of diagnosis; however, it may take several weeks to obtain a result. Recently some dermoscopic patterns that can be useful in the diagnosis of onychomycosis were described. However, published data on dermoscopic features of onychomycosis are still limited. Methods We performed a prospective dermoscopic study of patients with positive fungal culture between April and December 2016. Patients with a final diagnosis of psoriasis or lichen planus were excluded from the study. Dermoscopy (polarized and nonpolarized) was performed. Results Thirty-seven patients were enrolled, 24 women and 13 men (median ± SD age, 48.6 ± 16.1 years). Nail samples were culture positive for Trichophyton rubrum (89.2%), Trichophyton interdigitale (8.1%), and Candida albicans (2.7%). Distal and lateral subungual onychomycosis was the most frequent clinical subtype (59.5%). The most frequent dermoscopic features were subungual keratosis (73.0%), distal subungual longitudinal striae (70.3%), spikes of the proximal margin of an onycholytic area (59.5%), transverse superficial leukonychia (29.7%), and linear hemorrhage (13.5%). Brown chromonychia was most frequently seen with nonpolarized dermoscopy (66.6% versus 24%; P = .027). Conclusions Specific dermoscopic signs of onychomycosis are mostly related to the proximal invasion of the nail plate. Detection of these signs is simple and can, in some cases, help avoid mycologic testing.
