Fluconazole activity against four strains of Candida albicans (three isolates from AIDS patients and one azole-resistant isolate, NCPF 3363) was studied in a turkey crop infection model. Isolate NCPF 3363 showed confirmed azole resistance in vitro and in vivo. Two isolates from AIDS patients were susceptible to fluconazole in vitro and in vivo. The third isolate was resistant to fluconazole in vitro (MIC = 100 micrograms ml-1), insensitive to 2.5 mg kg-1 but sensitive in vivo to a 5 mg kg-1 daily dose.

Invasive fungal infections have become an increasingly serious threat to global human health, underscoring the urgent need for the development of new antifungal drugs. In this study, we found a natural polyphenolic compound 1,2,3,4,6-O-pentagalloyl-glucose (PGG), which is present in various plants and herbs. PGG showed broad-spectrum antifungal activities, enhancing the efficacy of fluconazole.

The incidence of non- infections has witnessed a substantial rise in recent decades. ), an opportunistic human fungal pathogen, is accountable for both superficial mucosal and life-threatening bloodstream infections, particularly in immunocompromised individuals. Distinguished by its remarkable resilience to environmental stressors, exhibits intrinsic tolerance to azoles and a high propensity to swiftly develop azole resistance during treatment.

In this study, copper nanoparticles with an average particle size of 2-4 nm were synthesized using the green extract of Thunb. The catalytic activity and dye degradation efficiency of Cu NPs were evaluated using ultraviolet spectroscopy. To confirm that Cu NPs can continuously remove organic dyes, this study used Cu/Lj-C composite material adsorbed on cotton balls as a simulated bed to study the cyclic catalytic activity of Cu NPs for the reduction of methylene blue by sodium borohydride (NaBH).
