The production of host-selective toxins by the necrotrophic fungus Alternaria alternata is essential for the pathogenesis. A. alternata infection in citrus leaves induces rapid lipid peroxidation, accumulation of hydrogen peroxide (H2O2), and cell death. The mechanisms by which A. alternata avoids killing by reactive oxygen species (ROS) after invasion have begun to be elucidated. The ability t...

cough until 2014. On day 3, chest X-ray was performed, with negative results and did not show any opacity in right and left side chest. Bronchoscopy revealed of the left bronchus thick purulent secretions that on day 5, sent to the Bacteriology Laboratory of the hospital, no bacteria were identified by Gram stain, but in modified Ziehl-Neelsen stain showed macroconidia of Alternaria (Figure 1)....

Fungal species were isolated from samples of damaged sunflower. The strains selected on the basis cultural and morphological characteristics belonged to Alternaria alternata, tennus Fusarium oxysporum, solan , fungal identified, as well strains, 67, termites, termarium, oxolbate 10, oxoliban 10 - 10.9%.

The objective of this study was to isolate and identify fungal species found in natural association with adults of Musca domestica. The adult insects were collected from two natural breeding grounds: hog pens and an urban sanitary landfill. The isolated fungi were identified as: Aspergillus flavus (23.8%), A. niger var. niger (14.4%), Penicillium corylophilum (21.4%), P. fellutanum (11.9%), Cla...

Phytoterpenoid isolated from Artabotrytis odoratissimus inhibited spore germination of some plant pathogenic as well as saprophytic fungi e.g. Alternaria alternata, A. solani, Cercospora sp., Curvularia maculans, C. pennisetti, Fusarium udum, Helminthosporium echinochlova, H. frumentacie, H. penniseti and Ustilago cynodontis. In Curvularia maculans and H. frumentacie, spore germination was comp...

In the search for new marine derived antibiotics, 43 epi- and endophytic fungal strains were isolated from the surface or the inner tissue of different marine plants and invertebrates. Through preliminary and secondary screening, 10 of them were found to be able to produce broad-spectrum antimicrobial metabolites. By morphological and molecular biological methods, three active strains were char...
