در تدوین برنامه های توسعه جنگل و فضای سبز خصوصا در مناطق خشک و نیمه خشک مطالعه و بررسی کلیه درختان و عناصر پوششی موجود در توده جنگلی مهم است. در این تحقیق 2/9 هکتار از عرصه جنگلکاری شده با گونه کاج سیاه (pinus nigra) فرودگاه ارومیه واقع در شمال شهر ارومیه از نظر تنوع پوشش علفی منطقه جنگلکاری شده، غنای گونه ای، یکنواختی و تنوع گونه ای ، مورد مطالعه قرار گرفت. لذا جهت بررسی تراکم و پوشش درختی تعد...
Background & Objective: Candida genus comprises diverse species of yeast and yeast like fungi that some of them especially candida albicans are parts of the normal flora of human body. They are opportunistic parasites that cause diseases. There are currently limited effective drugs against those fungi. Hence this may lead to the emergence of resistant species. The aim of present study was e...
Background and Aim: The occurrence of fungal species resistant to antifungal drugs and also their numerous side-effects have persuaded researchers to work on new therapeutic methods. The aim of the present study was to assess anticandidal activities of aqueous and methanol. extracts of walnut fruit, peel, and leaves on different Candida species. Materials and Methods: In the current ...
Background: Over the last two decades invasive candidiasis has become an increasing problem in neonatal intensive care units (NICUs). Colonization of skin and mucous membranes with Candida spp. is important factor in the pathogenesis of neonatal infection and several colonized sites are major risk factors evoking higher frequencies of progression to invasive candidiasis. The aim of this study w...
Objective(s) Shark Liver Oil (SLO) is an immunomodulator. Macrophages play a key role in host defense against pathogens like fungi. Candida albicans have mechanisms to escape immune system. We determined the effect of killed-Candida on the in vitro viability of macrophages and the effect of SLO on augmentation of this potency. Materials and Methods Peritoneal macrophages were separated and c...
The growing number of fungal infections, coupled with emerging resistance to classical antifungal agents, has led to the development of new agents, among them voriconazole. Susceptibility to voriconazole was tested by using two microdilution techniques: the reference method described in National Committee for Clinical Laboratory Standards document M27-A2 and a colorimetric method, Sensititre Ye...
The new colorimetric Vitek 2 YST card was evaluated for identification of yeasts (136 strains) with respect to the influence of different source media. The Vitek 2 YST card achieved satisfactory results for all yeast species tested, with the exception of Candida guilliermondii, Candida norvegensis, Candida parapsilosis, Candida rugosa, and Candida tropicalis. After simple additional tests, 93.7...
The effect of gentian violet against Candida albicans and non-Candida albicans biofilms formed on polymethylmethacrylate strips was evaluated using a dry weight assay and confocal laser scanning microscopy. The ability of gentian violet to inhibit Candida albicans germination was also assessed. Gentian violet activity against Candida biofilms was demonstrated by a reduction in dry weight, disru...
We report on the isolation of Candida nivariensis from a renal transplant patient with persistent candiduria. Biochemical profiling misidentified isolates as Candida glabrata (3/5) and Candida inconspicua (2/5). All isolates produced white colonies on CHROMagar(™) Candida medium. Internal transcribed spacer (ITS) ribosomal gene sequence analysis and MALDI-TOF-MS analysis (Bruker Biotyper(™) 2.0...
برای مدیریت اکوسیستمهای مرتعی اولین قدم، تعیین عوامل مؤثر بر پراکنش گونه ها و تنوع گونه ای است. در این تحقیق، رابطه بین تنوع گونه ای مراتع اشتهارد با عوامل محیطی (خاک و پستی و بلندی) بررسی شده است. در هر واحد (تیپ گیاهی)، نمونه برداری به روش تصادفی-سیستماتیک در طول 3 ترانسکت خطی 750 متری انجام شد. در طول هر ترانسکت 15 پلات با ابعادی که به روش حداقل سطح تعیین شد، به فاصله 50 متر قرار داده شد. د...
