We document the first case of haematogenous cerebral spread in Rhizopus arrhizus rhino-orbital mucormycosis, and of posaconazole related adrenal insufficiency. A patient presenting with diabetic ketoacidosis and sinusitis was treated with right medial maxillectomy, ethmoidectomy and IV liposomal amphotericin. Orbital exenteration was performed after intraorbital spread of infection. IV caspofun...
The conversion of zearalenone by various microorganisms was studied. A new polar metabolite was formed in addition to alpha- and beta-zearalenols. The structure of the new metabolite was determined as zearalenone-4-O-sulfate conjugate on the basis of enzymatic and acid hydrolysis, followed by mass spectrometry, nuclear magnetic resonance, and infrared spectroscopic analysis. The results obtaine...
این تحقیق بر روی جذب میکروبی یون فلزی کروم موجود در پساب آبکاری کارخانه ایران دوچرخ انجام گردیده است . که در آن از سوش rhizopus arrhizus استفاده گردیده است . در این روش از توده سلولی بعنوان یک جاذب استفاده می شود.
Preparation of some chloro, bromo and iodo steroids derived from testosterone and epiandrosterone is described. The biotransformation of halogenated products by fungus mucor plumbeus are preformed. Introduction of the halogen atom into the steroids moiety severely affected the biotransformation results. Keyword: Mucor plumbeus, biotransformation, steroids, 3dibromomethylene-5α-androstan-17-one....
OBJECTIVES Zygomycosis is an uncommon but devastating disease with few therapeutic options. Calcineurin inhibitors and sirolimus (mTOR inhibitor), commonly used in transplant patients as immunosuppressives, have antifungal activity. They are known to demonstrate synergy with triazoles against certain fungi, though limited data exist about their activity against zygomycetes. Our aim was to study...
Clinical breakpoints (CBPs) have not been established for the Mucorales and any antifungal agent. In lieu of CBPs, epidemiologic cutoff values (ECVs) are proposed for amphotericin B, posaconazole, and itraconazole and four Mucorales species. Wild-type (WT) MIC distributions (organisms in a species-drug combination with no detectable acquired resistance mechanisms) were defined with available po...
OBJECTIVES Mucormycosis is a rare but refractory mycosis with high mortality. Few therapeutic options are available and novel strategies are needed. Calcineurin inhibitors are known to have antifungal activity, including synergy with various antifungals. We examined the interaction of caspofungin with calcineurin inhibitors and sirolimus against Glomeromycetes. METHODS Twenty-six strains of G...
قارچ‌های بیماری‌زای بسیاری سبب ایجاد پوسیدگی ریشه چغندرقند در مراحل مختلف می‌شوند. در بین آن‌ها Rhizoctonia spp. سبب پوسیدگی‌های طوقه و ریشه، پوسیدگی خشک و پوسیدگی بنفش ریشه می‌شود (Whitney and Duffos 1986). پوسیدگی ریشه توسط قارچ Phytophthora drechsleri Tucker در مزارعی که ریشه چغندر در معرض رطوبت بیش از حد معمول خاک قرار دارد، مشاهده شده‌است (Habibi 1975). قارچ Fitzp. (Edson) Pythium aphanid...
