27. Antifungal activity of some Sternbergia taxa: effects on germ tube and biofilm formation
Natural products are rapidly becoming the primary sources of novel antimicrobial agents, as resistance to existing antimicrobial agents is increasing. Apart from determining the antimicrobial activity of natural products, it is also important to understand their effects on the virulence factors of microorganisms. This study aimed to determine the antimicrobi

28. Analysis of the Seasonal Variation in Chemical Profile of Piper glabratum Kunth Essential Oils Using GC×GC/qMS and Their Antioxidant and Antifungal Activities
Piper glabratum is a plant native from South America, which has been little studied, despite its use in folk medicine. In this study, chemical composition, antioxidant and antifungal activities of essential oils (EOs) from leaves of P. glabratum were investigated. The influence of seasonality on its chemical composition was also evaluated. The chemical chara

31. Antifungal effect of sesame medicinal herb on Candida Species: original study and mini-review
The aim of this study was to evaluate the antifungal susceptibility patterns of three antifungals, methanolic extracts and N-hexane oil of sesame seeds on C. albicans and C. glabrata, isolated from oral cavity of liver transplant recipients. The results were compared with other reports to develop a mini review as well. Candida species were isolated from live

32. Partial characterization of ethanolic extract of Melipona beecheii propolis and in vitro evaluation of its antifungal activity
ABSTRACT The ethanolic extract of Melipona beecheii Bennett 1831, propolis from Yucatán Mexico was evaluated in vitro for the determination of its phenolic compound content, antioxidant capacity and antifungal activity. The results were compared against those of the ethanolic extract of Apis mellifera propolis. The total phenolic content, flavonoid content

33. Geopropolis gel for the adjuvant treatment of candidiasis – formulation and in vitro release assay
ABSTRACT The geopropolis produced by the stingless bee Melipona subnitida (popularly called "jandaíra" in Brazil) is a mixture of resin, wax, and mud. This study analyzed the antifungal activity of the geopropolis extract from Candida spp., developed a gel formulation with this extract and analyzed the delivery of bioactives (kinetics release) in the formul

34. Ants Promote Germination of the Tree Guarea guidonia by Cleaning its Seeds
ABSTRACT Ants interact with seeds, and frequently remove their appendages. This work aimed to evaluate the effect of ants on the germination of Guarea guidonia (Meliaceae) seeds through removing the fleshy tissue of their integument (sarcotesta). The seeds were subjected to the following treatments: control (no sarcotesta removal), manual removal, and remova

36. Antifungal efficiency of chemically and thermally-activated acrylic resins after surface treatment using poly (diallyldimethylammonium chloride)
Abstract INTRODUCTION: Acrylic resins are used in the preparation of facial prostheses and may be colonized by fungi. Here, we verified the antifungal efficacy of this material after surface treatment using poly (diallyldimethylammonium chloride). METHODS: Acrylic resin specimens with and without surface treatment were subjected to tests for fungistatic an
