Fusarium Strains Isolated from Human Mycotic Keratitis

the role of russia in transmission of energy from central asia and caucuses to european union

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...

Growth Inhibition of Aspergillus flavus Isolated from Pistachio by Secondary Metabolites

Pistachio nut is a strategic product throughout the world, especially in Iran. There are some problems that reduce production and export of pistachios, for example, postharvest fungi, especially Aspergillus spp., that lead to production of mycotoxins. Nowadays the use of chemical and synthetic antifungals is discouraged and reduced because of health risks to mankind and nature. In present study...

Toxicity of Some Fusarium Section Sporotrichiella Strains

The relationship between the toxicities of crude extracts and purified toxins of Fusarium spp. belonging to the section SporotrichieUla has been assessed. Toxicity was determined on the basis of death ofArtemia salina larvae and of viability and blastogenic response of bovine and human lymphocytes. Trichothecene-producing strains ofFusarium sporotrichioides and Fusarium poae were toxic toA. sal...

Detection of antibiotic resistance genes in some Lactococcus garvieae strains isolated from infected rainbow trout

The present study was done to evaluate the presence of antibiotic resistance genes in Lactococcus garvieae isolated from cultured rainbow trout, West Iran.The isolates were examined for antimicrobial resistance using disc diffusion method. Of the 24 strains tested, 21 were resistant to ampicillin (87.5%), 9 to erythromycin (37.5%) and 19 to tetracycline (79.1%). Fourteen strains were resistant ...
