natural plant extracts / products have the potential as safe alternatives for chemical fungicides in plant disease management. methanol and pure methanol: water (50:50 v/v) extracts of peppermint, lavandula, eucalyptus, datura and nettle were screened for their antifungal activity against alternaria sesami, the causal agent of alternaria leaf spot of sesame at 5, 10 and 15% concentrations in sh...

The prevalence of invasive fungal infections has increased significantly during organ transplantation, cancer chemotherapy and allogeneic bone marrow transplantation. However, only a limited number of antifungal agents are currently available for the treatment of life-threatening fungal infections. Although new antifungal agents have been introduced in the market, the development of resistance ...

background and objectives: to find antagonistic bacteria with potential antifungal activity against some pathogenic fungi, including aspergillus niger , a. flavus, fusarium moniliforme and penicillium marneffei , a total of 148 agricultural soil samples from different sites of tehran were examined.  materials and methods: antagonistic soils were selected by screening against a. niger on glucose...

Background and Purpose: Microorganism-based synthesis of nanostructures has recently been noted as a green method for the sustainable development of nanotechnology. Nowadays, there have been numerous studies on the emerging resistant pathogenic bacteria and fungal isolates, the probable inability of bacteria and fungi to develop resistance against silver nanoparticles’ (SNPs) antibacte...

Sea cucumber is presented as potential marine source of antimicrobial compounds. The purpose of this study is to evaluate antifungal effects of sea cucumber, Holothuria leucospilota, extracts on Aspergillus niger and Candida albicans. Methanol and chloroform extracts of the body wall, gonad and intestine of sea cucumber, H. leucospilota, collected from Persian Gulf, were evaluated for their ant...

AIMS To characterize and explore the potential in extracellular biosynthesis of silver nanoparticles (AgNPs) by Penicillium chrysogenum and Aspergillus oryzae and to investigate the antifungal effect of chemically vs biologically synthesized AgNPs comparing with conventional antifungal drugs against Trichophyton rubrum. METHODS AND RESULTS Chemically synthesized AgNPs (Chem-AgNPs) coated with...

S100A8 and S100A9 and their heterocomplex calprotectin (S100A8/A9) are abundant cytosolic constituents in human neutrophils previously shown to possess antifungal activity. This study was designed to investigate mechanisms involved in the modulation of the antifungal properties of S100A8/A9. S100A8, S100A9 and site-directed mutants of both proteins were tested for their antifungal effect agains...

Candida albicans is an opportunistic pathogen that causes candidiasis in humans. In recent years, metabolic pathways in C. albicans have been explored as potential antifungal targets to treat candidiasis. The glyoxylate cycle, which enables C. albicans to survive in nutrient-limited host niches and its. Key enzymes (e.g., isocitrate lyase (ICL1), are particularly attractive antifungal targets f...

Antimycotic chemosensitization and its mode of action are of growing interest. Currently, use of antifungal agents in agriculture and medicine has a number of obstacles. Foremost of these is development of resistance or cross-resistance to one or more antifungal agents. The generally high expense and negative impact, or side effects, associated with antifungal agents are two further issues of c...

The petroleum ether, chloroform, acetone, methanol and aqueous extracts of the aerial parts of Leptadenia reticulata Wight and Arn. (Asclepiadaceae) were studied for in vitro antifungal activity against Aspergillus flavus, Aspergillus ruantti, Candida tropicalis, Candida albicans, Trichodermata viride and Trichodermata koningii respectively. The methanolic extract exhibited prominent antifungal...
