Amiodarone has intrinsic anti-Trypanosoma cruzi activity and acts synergistically with posaconazole.
There is no effective treatment for the prevalent chronic form of Chagas' disease in Latin America. Its causative agent, the protozoan parasite Trypanosoma cruzi, has an essential requirement for ergosterol, and ergosterol biosynthesis inhibitors, such as the antifungal drug posaconazole, have potent trypanocidal activity. The antiarrhythmic compound amiodarone, frequently prescribed for the sy...
Antifungal activity of Bacillus coagulans creates the possibility to use this microorganism in biological control of fungal plant pathogens. Activity of Bacillus coagulans (No 6), isolated from lupine compost, against seven pathogenic species of indicator fungi: Bipolaris sorokiniana, Trichothecium roseum, Rhizoctonia solani, Sclerotinia sclerotiorum, Fusatium oxysporum, Fusarium solani and Fus...
Antifungal azoles inhibit ergosterol biosynthesis by interfering with lanosterol 14α-demethylase. In this study, seven upregulated and four downregulated ergosterol biosynthesis genes in response to ketoconazole treatment were identified in Neurospora crassa. Azole sensitivity test of knockout mutants for six ketoconazole-upregulated genes in ergosterol biosynthesis revealed that deletion of on...
Sixty four samples of cocoa beans replicated in quadruplicates were collected from five warehouses from southwest Nigeria and examined for fungal loads, ergosterol and ochratoxin A The levels of all the variables obtained were further used as indices for cocoa grading into food quality, FoQ (erg < 5 mg/kg; OTA < 1 µg/kg), feed quality, FeQ (erg = 5~10 mg/kg; OTA in the range of 1.1~3.11 µg/kg),...
Cultured mycelium Cordyceps sinensis (CMCS) is a Chinese herbal medicine, which is widely used for a variety of diseases including liver injury in clinic. The current study aims to investigate the protective effects of CMCS against liver fibrosis and to exploit its active antifibrotic substances in vivo and in vitro. For evaluating the antifibrotic effect of CMCS and ergosterol, male C57BL/6 mi...
Ergosterol and 3-hydroxy fatty acids, chemical markers for fungal biomass and the endotoxin of gram-negative bacteria, respectively, may be useful in studies of health effects of organic dusts, including domestic house dust. This paper reports a method for the combined determination of ergosterol and 3-hydroxy fatty acids in a single dust sample and a comparison of these chemical biomarkers det...
BACKGROUND Recent epidemiological studies suggest that the adverse respiratory health effects caused by the inhalation of fungal propagules are substantial. Knowledge of the prevalence and environmental determinants of indoor fungal levels is essential in designing effective avoidance measures. AIM To investigate the prevalence of fungi and the influence of residential characteristics on leve...
ABSTRACT Membrane phase separation to form micron-scale domains of lipids and proteins occurs in artificial membranes; however, a similar large-scale has not been reported the plasma membrane living cells. We show here that stable protein-depleted region is generated yeast mutants lacking phosphatidylserine at high temperatures. named this ‘void zone’. Transmembrane certain peripheral phospholi...
ABSTRACT To investigate the interaction between two major ear-rotting pathogens, maize ears were inoculated with either Fusarium graminearum, F. moniliforme, or an equal mixture of the two. Silk and kernel tissues were periodically harvested throughout the growing season so that a time course of the experimental variables (disease severity, ergosterol content, fungal DNA content, and mycotoxin ...
In the present study the mould incidence, ergosterol and aflatoxin B1 (AFB1) contaminations were evaluated in different food based seed samples viz., chickpea, cowpea, green gram, groundnut, Indian bean, maize, sorghum, soya bean and sunflower collected from different agro-climatic regions of Karnataka (India). The agar plate and standard blotter methods were employed for determination of the f...
