AI Article Synopsis
- A 50% ethanol extract from Hedera helix leaves was analyzed for its content of polyphenols and sterols, revealing the presence of compounds like rutin, quercetin, kaempferol, and stigmasterol.
- The antifungal properties of this extract were tested against various phytopathogenic fungi, with an observed minimum inhibitory concentration (MIC) ranging from 10-14%, which was comparable to the synthetic antifungal fluconazole.
- This study marks the first assessment of the antifungal effects of ivy leaf extract on these specific fungal species, and suggests its potential use for managing plant diseases and possibly human health issues.
Article Abstract
The 50% ethanol extract obtained from Hedera helix leaves was investigated regarding the presence and quantity of polyphenols, sterols and in vitro antifungal activity against phytopathogenic fungi. The chemical analysis revealed the presence of rutin, quercetin and kaempferol in the non-hydrolysed sample and quercetin and kaempferol in the hydrolysed sample and stigmasterol in the ivy leaf extract (nonhydrolysed sample). The antifungal activity against phytopathogenic fungi (Aspergillus niger, Botrytis cinerea, B. tulipae, Fusarium oxysporum f. sp. tulipae, Penicillium gladioli, and Sclerotinia sclerotiorum) was assessed using an agar dilution assay. The results are expressed as the minimum inhibitory concentration (MIC = 10-14%) and were compared to a synthetic antifungal drug - fluconazole (MIC = 8-30%). This report presents the first screening of the antifungal activity of the ivy leaf extract on these plant pathogenic fungi species, aiming to use the ivy leaf extract for controlling different diseases of vegetables and ornamental plants, in addition to human disorders.

Infections of intact and damaged skin barriers and keratin are frequently associated with complex biofilm communities containing bacteria and fungi, yet there are limited options for successful management. This study intended to focus on the utility of some novel proprietary lactam molecules, quorum sensing (QS)-derived halogenated furanones, which act to block the QS pathway, against key fungal pathogens of the skin (Candida albicans, Malassezia furfur and Microsporum gypseum). Moreover, we aimed to assess how these actives performed against complex interkingdom biofilms in a clinically relevant model.

An 83-year-old male with a history of radial keratotomy and laser-assisted in situ keratomileusis (LASIK) presented with symptoms of a non-resolving corneal ulcer in the right eye that had been present for five months. The patient was treated with antibacterial, antiviral, and antifungal medications over that period, with multiple recurrences that prompted referral to our tertiary center for management. Following a 48-hour cessation of all medications, a corneal biopsy was performed which grew .

Cellobiose lipids (CBLs) are a class of glycolipid biosurfactants produced by various fungal strains. These compounds have gained significant interest due to their surface-active and antifungal properties, which are comparable to traditional synthetic surfactants and antimicrobials. Despite their potential applicability in various cosmetic, pharmaceutical, and agricultural formulations, significantly less research has been focused on their production and purification in comparison to other glycolipid biosurfactants, such as mannosylerythritol lipids (MELs) and sophorolipids.

The synthesis of nanomaterials from PGPB is an exciting approach and it's often used in agriculture as nano-fertilizers and nano-pesticides. The present study reports a new approach to biosynthesis of silver nanoparticles (AgNP), using bacterial metabolites as agents to reduce Ag, which will remain as coating agents able to prevent microbial growth. Silver NP were biosynthesized using the bacterial metabolites produced by the beneficial strain Pseudomonas sp.
