Candida albicans, an opportunistic fungal pathogen, causes a wide variety of human diseases such as oral thrush and disseminated candidiasis. Many aspects of C. albicans physiology have been studied during liquid growth, but in its natural environment, the gastrointestinal tract of a mammalian host, the organism associates with surfaces. Growth on a surface triggers several behaviors, such as biofilm formation, invasion, and thigmotropism, that are important for infection. Recent discoveries have identified factors that regulate these behaviors and revealed the importance of these behaviors for pathogenesis.

A novel molecular design based on a quinazolinone scaffold was developed the attachment of aryl alkanesulfonates to the quinazolinone core through a thioacetohydrazide azomethine linker, leading to a new series of quinazolinone-alkanesulfonates 5a-r. The antimicrobial properties of the newly synthesized quinazolinone derivatives 5a-r were investigated to examine their bactericidal and fungicidal activities against bacterial pathogens like , (Gram-positive), , , (Gram-negative), in addition to (unicellular fungal). The tested compounds demonstrated reasonable bactericidal activities compared to standard drugs.

In this work, microalgae-based zinc oxide nanoparticles loaded with electrospun polyvinyl alcohol (PVA)/sodium alginate (SA) nanofibers were fabricated by electro-spinner. PVA/SA fibrous mats were crosslinked by citric acid, which enhanced their thermal stability and swelling behavior. Green-synthesized ZnO NPs were laboratory synthesized and characterized by FTIR, XRD, EDX, SEM, TEM and TGA analyses.

Introduction: Antimicrobial resistance and free radical-mediated oxidative stress and inflammation involved in many pathological processes have become treatment challenges. One strategy is to search for antimicrobial and antioxidant ingredients from natural aromatic plants. This study established a rapid and high-throughput effect-component analysis method to screen active ingredients from Ligusticum chuanxiong essential oil (CXEO).

Background: Vulvovaginal candidiasis (VVC), caused primarily by Candida albicans, is currently treated with either prescription or over-the-counter antifungal drugs, often with variable efficacy and relapses. New and improved therapeutic strategies, including drug-free treatment alternatives, are needed. Upon overgrowth or environmental triggers, C.
