BACKGROUND Labisia pumila, locally known as Kacip Fatimah, is a forest-floor plant that has tremendous potential in the herbal industry. It is one of the five herbal plants identified by the government as one of the national key economic areas to be developed for commercial purposes. There are three varieties of L. pumila namely, L. pumila var. pumila, L. pumila var. alata and L. pumila var. la...
Fifty-two isolates of Fusarium species were obtained from soybean seeds from various parts of Korea and identified as Fusarium oxysporum, F. moniliforme, F. semitectum, F. solani, F. graminearum, or F. lateritium. These isolates were grown on autoclaved wheat grains and examined for toxicity in a rat-feeding test. Nine cultures were toxic to rats. One of these, a culture of Fusarium sp. strain ...
Strains of Pseudomonas putida, Pseudomonas sp., and Pseudomonas aeruginosa were examined for their ability to grow in the presence of the iron chelator, ethylenediamine-di-(o-hydroxyphenylacetic acid). In vitro fungal inhibition assays showed that the isolates varied in their ability to inhibit the growth of representative fungal plant pathogens. Fungal inhibition in vitro was superior to that ...
Fusarium commune sp. nov. was isolated from soil and Pisum sativum in Denmark and several widespread locations within the northern hemisphere from diverse substrates including white pine, Douglas fir, carnation, corn, carrot, barley and soil. Fusarium commune is characterized by and distinguished from its putative sister taxon, the F. oxysporum complex, in having long, slender monophialides and...
بوته میری یا damping off از بیماریهای شایع نهالستانهای جنگلی میباشد که همه ساله خسارتهای زیادی را به نهالستانها وارد میکند. از آن جا که کاهش این خسارتها مبتنی بر شناخت عوامل بیماریزا و سپس کنترل آنها می باشد، بازدیدهایی طی سالهای 1384 و 1385 از نهالستان لاکان بهعمل آمد. نهالهای بیمار پس از جمعآوری و انتقال به آزمایشگاه مورد بررسی قرار گرفتند که عوامل بیماریزای بدست آمده بعد از انجام آزمای...
for determination the host range of fusarium stem and root rot of green-house cucumber (cucumis sativus) that caused by fusarium oxysporum f. sp. radicis-cucumerinum, after isolation, identification and study of pathogenisity, 16 species of several plant families were artificially inoculated with this pathogen by sand and corn meal contaminated with pathogen, two varieties of cucumis melo, of c...
Although numerous studies have been conducted on microbial contaminants associated with various stages related to poultry and meat products processing, only a few reported on fungal contamination of poultry litter. The goals of this study were to (1) characterize litter fungal contamination and (2) report the incidence of keratinophilic and toxigenic fungi presence. Seven fresh and 14 aged litt...
A total of 82 isolates of microfungi were isolated from 6 sandy soil samples collected from Teluk Aling beach, Pulau Pinang. The soil microfungi were isolated by using direct isolation, debris isolation and soil dilution techniques. Based on morphological characteristics, seven genera of microfungi were identified namely, Fusarium (42%), Aspergillus (24%), Trichoderma (13%), Curvularia (9%), Co...
پوسیدگی ریشه و طوقه گوجه فرنگی ناشی از قارچ oxysporum fusarium با دو فرم مخصوص f. o. f. sp. lycopersici و f. o. f. sp. radicis – lycopersici از مهمترین بیماریهای این گیاه می باشد. به کارگیری ارقام مقاوم و رعایت تناوب چند ساله از روش های کنترل این بیماری می باشد. از سویی استراتژی کنترل زیستی این بیماری با استفاده از میکروارگانیسم های آنتاگونیست نیز توسط محققین به کار رفته است. در این پژوهش میز...
Tracheoesophageal vocal prostheses (TVP) in laryngectomized patients commonly deteriorate due to overgrowth by yeasts, particularly Candida species. We describe the first case of colonization of such devices by a member of the Fusarium solani species complex in a patient with a history of glottal carcinoma. Three isolates, from three prostheses, were found morphologically consistent with the tr...
