Fusarium species colony and microscopic description. To study fungal spores, basidia, cystidia, sphaerocysts and other tiny features of fungi you will need a microscope capable of at least x 400 magnification. Septate branching hyphae were observed on microscopic examination of the pus using toluidine blue O stain (figures 3 3 – 5). In fact, the taxonomy of the Fusarium genus has changed many times throughout history. Microscopic view of Aspergillus spp. Microscopic view of spores (conidia) of Fusarium virguliforme. Fusarium wilt is a warm-weather disease, most prevalent on acid, sandy soils. Thus, Fusariosis is the name given to the disease caused in plants by certain species of Fusarium fungi (phytopathogens), which in this case develop as parasites. Microscopic appearance — Microscopically, the hyphae of Fusarium in tissue resemble those of Aspergillus species, with septate hyaline hyphae 3 to 8 microns in diameter that typically branch at acute angles (picture 1 and picture 2). The fungi that cause Fusarium wilt diseases are composed of a group of host-specific forms (forma specialis) abbreviated f. sp. Background Clinical outcomes in fungal keratitis vary between Fusarium and Aspergillus spp, therefore distinguishing between species using morphological features such as filament branching angles, sporulation along filaments (adventitious sporulation) or dichotomous branching may be useful. Some are common plant pathogens, which can damage seeds and seedlings and cause root rot. Chlamydospores are the third type of spore and are either one or two celled. Fusarium wilt is the most destructive fungal disease affecting banana plantation across the globe [1, 2, 3, 4].It is caused by a type of soilborne fungal called Fusarium oxysporum f. sp. Phialides grouped in brush-like clusters (penicilli) at the ends of the conidiophores; conidia unicellular, round to ovoid, hyaline or pigmented, rough walled or smooth, in chains. A. Summerrell.2006). The pathogen is soilborne and remains in infested soils for up to ten years. isolates were propagated onto Potato Dextrose Agar (PDA) by using single-spore method. Fusarium proliferatum produces microscopic, long, canoe-shaped spores called conidia. >> VIEW COURSES Participate See our news section.
