Allergens of the entomopathogenic fungus Beauveria bassiana
BACKGROUND: Beauveria bassiana is an important entomopathogenic fungus currently under development as a bio-control agent for a variety of insect pests. Although reported to be non-toxic to vertebrates, the potential allergenicity of Beauveria species has not been widely studied. METHODS: IgE-reactivity studies were performed using sera from patients displaying mould hypersensitivity by immunob...
متن کاملAdhesion of the entomopathogenic fungus Beauveria (Cordyceps) bassiana to substrata.
The entomopathogenic fungus Beauveria bassiana produces at least three distinct single-cell propagules, aerial conidia, vegetative cells termed blastospores, and submerged conidia, which can be isolated from agar plates, from rich broth liquid cultures, and under nutrient limitation conditions in submerged cultures, respectively. Fluorescently labeled fungal cells were used to quantify the kine...
متن کاملSurface characteristics of the entomopathogenic fungus Beauveria (Cordyceps) bassiana.
Marked differences in surface characteristics were observed among three types of single-cell propagules produced by the entomopathogenic fungus Beauveria bassiana. Atomic force microscopy (AFM) revealed the presence of bundles or fascicles in aerial conidia absent from in vitro blastospores and submerged conidia. Contact angle measurements using polar and apolar test liquids placed on cell laye...
متن کاملCompatibility of the entomopathogenic fungus Beauveria bassiana with the insecticides fipronil, pyriproxyfen and hexaflumuron
سازگاری سه حشره‌کش فیپرونیل، پایری‌پروکسی‌فن و هگزافلومورون با جدایه‌ی DEBI 002 (آتشگاه) قارچ Beauveria bassiana مورد بررسی قرار گرفت. برای تعیین اثر این حشره‌کشها روی جوانه‌زنی اسپور قارچ، غلظت‌های مختلف آن‌ها به محیط کشت مالت آگار اضافه شد. به‌منظور محاسبه‌ی میزان رشد میسیلیوم در تیمارهای مختلف، قطر کلنی اندازه‌گیری شد و ارزیابی میزان اسپورزایی با شمارش اسپورها در واحد سطح صورت گرفت. نتایج نش...
متن کاملvirulence of some isolates of entomopathogenic fungus, beauveria bassiana on ostrinia nubilalis (lepidoptera: pyralidae) larvae
the european corn borer (ecb) is one of the most important insect pests of corn and some other crops such as rice in iran. this pest is one of the most important hosts of the entomopathogenic fungus beauveria bassiana, a well known fungal entomopathogen with high host range and considerable potential in insect pest control. in an isolate selection program of fungal isolates against ecb, ten iso...
