Background: Medicinal plants are widely used to treat infectious diseases, metabolic disorders and cancer. Argemone mexicana L. (A. mexicana), commonly found on desolate land of Marathwada (Maharashtra, India) has been used to treat oral cavity infections. Methods: In this study, cold aqueous and methanolic extracts were prepared from A. mexicana stem and leaves. These extracts were tested for ...
High mortality rates from invasive aspergillosis in immunocompromised patients are prompting research toward improved antifungal therapy and better understanding of fungal physiology. Herein we show that Aspergillus fumigatus, the major pathogen in aspergillosis, imports exogenous cholesterol under aerobic conditions and thus compromises the antifungal potency of sterol biosynthesis inhibitors....
Zygomycosis is increasingly recognized in immunocompromised hosts. We investigated whether platelets become activated after contact with Zygomycetes and adhere to conidial and hyphal structures using immunofluorescence. The platelets' influence on fungal viability was evaluated by assessing hyphal elongation and hyphal damage. Platelets became activated and strongly adhered to conidia and hypha...
members of the genus bacillus are among the most promising candidates for biological control of plant pathogenic bacteria. in this study, cell free supernatants of three strains b. subtilis utb96, b. subtilis utb1 and b. subtilis utb70 against aspergillus flavus r5 were investigated using dual culture assay. strain b. subtilis utb96 showed the highest inhibition effect. thin lyer chromatography...
Sequential extracts of some medicinally important arid zone plants of Rajasthan, viz. Lepidagathis trinervis Nees., Polycarpea corymbosa Lam. and Sericostoma pauciflorum Stocks. ex Wight. were tested against six bacterial (Gram +ve and Gram -ve) and five fungal strains using agar well diffusion method. Ethyl acetate extract of L. trinervis showed maximum activity against Bacillus subtilis, Ente...
Trichophyton rubrum and Trichophyton mentagrophytes complex, or Trichophyton spp. are the main etiologic agents of dermatophytosis, whose treatment is limited by the high cost of antifungal treatments, their various side effects, and the emergence of resistance amongst these species. This study evaluated the in vitro antidermatophytic activity of 23 crude extracts from nine plant species of sem...
Amphotericin B is a fungicidal substance that is treatment of choice for most systemic fungal infections affecting as cryptococcosis the immunocompromised patients. However, severe side effects have limited the utility of this drug. The aim of this study was to evaluate the antifungal effect of the combination of amphotericin B with quercetin or rutin and as a protective of citotoxic effect. Th...
Fungal infections have become a major public health problem, growing in number and severity in recent decades due to an increase of immunocompromised patients. The use of therapeutic agents available to treat these fungal infections is limited by their toxicity, low bioavailability, antifungal resistance, and high cost of treatment. Thus, it becomes extremely important to search for new therape...
Fig. 1. StcJrol hiosynthesis squalene to lanosterol. This enzyme has been shown to hc essential f o r fungi; Sacchurornyces cerevisiue mutants lacking this key enzyme in fact require exogenous ergosterol supplementation for growth 121. Even if these early steps in sterol biosynthesis are common to mammals and fungi, the example of the allylamines. which act on squalene epoxidase 131. shows that...
Leptadenia pyrotechnica was evaluated for its antifungal activity against some pathogenic fungi. Extracts in different organic solvents were used for disc diffusion assay. Hexane and ethyl acetate extracts have showed maximum inhibition zone against A. niger (15mm and 12.2 mm respectively). Methanol extract showed maximum activity against F. oxysporium (13.0mm) and A. flavus (15mm) while aqueou...
