Some members of the familyClavicipitaceae are endophytic and have mutualistic relationship with the plant family Poaceae. Their relationship is beneficial for both host and fungus. In the present investigation, endophytic fungi were isolated from seed and leaf sheath of hosts Festuca arundinacea, F. ovina, F. pratensis, Bromus tomentellus, Melica persica and Lolium prenne. Morphological charact...

the genus malasezia currently includes fourteen species that have been isolated from healthy and diseased human and animal skin. however, there were differences with respect to the species most commonly isolated, not only in patients with various skin diseases but also between healthy individuals. the aim of this study was to analyze the prevalence of malassezia species from clinically normal s...

collection of multiple processes that increase the chronological age of an organism leading to death is defined as aging, and even though important, it is poorly understood. recent research has shown that aging is due to biochemical and genetic changes, in interaction with environmental effects, including diet and nutrition. most knowledge on aging is based on ge­netic model system, but its mol...

background : lactobacilli are the well known friendly bacteria for their probiotic activities against pathogens. the inhibitory activity of different strains of lactobacilli either obtained as commercial products or isolated from human feces was investigated against the clinical isolates of pseudomonas aeruginosa. the isolates were selected as the most resistant strains when challenged with ant...

lipophilic yeast of the genus malassezia (pityrosporum) belongs to the normal flora of human skin and many warm-blooded animals. these fungi can produce a diverse range of diseases that the best known and most frequent of them is pityriasis versicolor, a chronic recurrent skin disease occurring primarily in tropical regions. the genus malassezia has been recently enlarged to include seven disti...
