Abstract:

Pathogenic Candida species are widely distributed in human and animal hosts. Accordingly, they account for 88% of nosocomial fungal infections and are the fourth cause of hospital-acquired blood infections. Fresh Garlic (Allium sativum) contains a sulfur compound that is composed of an amino acid (cysteine) called Alliin. The compounds in garlic are divided into two groups of sulfur and nonsulfur-containing types. In this study, the standard specimens of different Candida species were cultured on Sabouraud dextrose agar (Merck) and chromogen agar Candida. The extracted essential oil was stored in a sterile container with a lid at 4°C for laboratory analysis. The extraction was accomplished using hydrodistillation by means of Clevenger apparatus. Comparison of the minimum inhibitory concentrations of garlic essential oil showed that C. albicans was the most susceptible Candida species to this plant essential oil. In other words, garlic essential oil inhibited the fungal growth at the lowest concentration. Candida species has been well accepted as the most important etiologic agent of oral candidiasis. Therefore, the control of infections caused by C. albicans and C. glabrata, as well as the early diagnosis and prevention of candidiasis, is a matter of particular importance. The adoption of an accurate treatment requires the identification of Candida species and genotype analysis of clinical isolates, which also facilitate the evaluation and prevention of candidiasis, especially among inpatients.

In vitro antifungal activities of Euphorbia macroclada and fluconazole against pathogenic Candida species

Background and Purpose: Candida species constitute an important group of opportunistic fungi, which cause various clinical diseases. Considering the resistance of some Candida species to conventional antifungal agents, treatment of such cases may be challenging and complicated. The purpose of this study was to evaluate and compare the antifungal activities of Euphorbia macroclada latex and fluc...

Antifungal Properties of Chenopodium ambrosioides Essential Oil Against Candida Species

The essential oil of the aerial part (leaves, flowers and stem) of Chenopodium ambrosioides was obtained by hydrodistillation and its chemical composition analyzed by GC and GC/MS, which permitted the identification of 14 components, representing 98.8% of the total oil. Major components were α-terpinene (51.3%), p-cymene (23.4%) and p-mentha-1,8-diène (15.3%). The antifungal properties of this ...

Activities of garlic oil, garlic powder, and their diallyl constituents against Helicobacter pylori.

Chronic Helicobacter pylori disease is reduced with Allium vegetable intake. This study was designed to assess the in vivo anti-H. pylori potential of a variety of garlic substances. The garlic materials all showed substantial but widely differing anti-H. pylori effects against all strains and isolates tested. The MICs (range, 8 to 32 microg/ml) and minimum bactericidal concentrations (MBCs) (r...
