The effects of caspofungin combined with amphotericin B were investigated with Candida glabrata. Although in vitro experiments showed an indifferent interaction, the combination regimen was the only therapeutic approach yielding organ sterilization in a murine candidemia model.

Background And Objectives: Understanding the epidemiology of species among cancer patients is crucial for preventing invasive infections. This study aimed to identify species and assess risk factors among cancer patients receiving chemotherapy in Birjand, eastern Iran.
Materials And Methods: The samples were obtained from the oral cavity of 140 patients and the initial identification of species was carried out through fungal cultures.

(), the second most prevalent Candida pathogen globally, has emerged as a major clinical threat due to its ability to develop high-level azole resistance. In this study, two new 5,6-dihydrotetrazolo[1,5-]quinazoline derivatives ( and ) were synthesized and characterized using IR, LC-MS, H, and C NMR spectra. Along with 13 previously reported analogues, these compounds underwent in vitro antifungal testing against clinical isolates using a serial dilution method (0.

In this study, metagenomic analysis was employed to investigate the bacterial communities in the Muan tidal mudflat of the Republic of Korea. We used metagenomic analysis to identify the microbial community in tidal soil dominated by Proteobacteria. From this environment, the bacterial strain, sp.

is the second most common cause of invasive candidiasis and is widely known to have reduced susceptibility to fluconazole relative to many other spp. Upc2A is a transcription factor that regulates ergosterol biosynthesis gene expression under conditions of sterol stress such as azole drug treatment or hypoxia. Through an microevolution experiment, we found that loss-of-function mutants of the ATF/CREB transcription factor suppresses the fluconazole hyper-susceptibility of the ∆ mutant.

Objectives: To evaluate the antifungal activity of extracts and compounds from against clinically relevant species, notably , and investigate possible mechanisms of action using electron microscopy and techniques.
Methods: Extracts and fractions of were obtained through turboextraction and partitioning, while the isolated compounds were previously purified. The ethyl acetate fraction (EAF) was characterized by HPLC.
