Candida albicans, a significant commensal fungus in the human gut, causes a wide spectrum of opportunistic infections. In a recent study, Yang et al. revealed the importance of a host-associated gut signal, GlcNAc, in C. albicans and described its significant role towards achieving a successful commensal-virulence trade-off program in the human body.

Candida is a commensal fungus of clinical interest that commonly lives in oral cavity and intestine but can become an opportunist microrganism and cause severe infections. A serie of 10 aminochalcones were designed and synthetized to obtain compounds anti-Candida with potent and broad-spectrum activity. The most active compound J34 demonstrated excellent in vitro activity against Candida albicans, Candida tropicalis, Candida parapsilosis, Candida glabrata and Candida krusei with minimum inhibitory concentration between 1.

Piperazine-based compounds have garnered significant attention due to their notable biological and pharmacological activities, making them essential in fine chemical and pharmaceutical applications. In this study, we managed to synthesize a novel hybrid bis-cyanoacrylamide bearing the piperazine core via phenoxymethyl linker and incorporating sulphamethoxazole moiety. The novel compound was fully characterized using different spectral data including 1H-NMR, C-NMR, and FTIR spectroscopy.

The antifungal drugs of the echinocandin family show high efficacy against Aspergillus fumigatus. However, their paradoxical effect, which restores fungal growth at high drug concentrations, and the emergence of resistant strains necessitate improvements. We identified 13 fluoroquinolone compounds from a chemical library containing 10,000 compounds that potentiate the antifungal activity of caspofungin.

Objective: Study on the impact of medical wound dressing compositions on reference strains of microorganisms in vitro conditions.
Materials And Methods: The study compared the antimicrobial activity of three types of dressing materials (DM): iodoform gauze bandage, DM with furagin and sodium alginate, DM from hydrogel with dimexide and silver nitrates. Gauze bandage with chlorhexidine was used as a control.
causes more than 400,000 life-threatening, and half a billion mucosal infections annually. In response to infection, the host limits availability of essential micronutrients, including zinc, to restrict growth of the invading pathogen. As assimilation of zinc is essential for pathogenicity, its limitation induces the secretion of the zincophore protein Pra1 to scavenge zinc from the host.
