introduction : nowadays, attention to foods free from chemical preservatives is on the rise. recently, consumers have concerned about foods containing these preservatives in their formulation .therefore,the use of antimicrobial peptides produced by lactic acid bacteria (lab) are strongly highlighted. ribosomally-synthesized peptides, which possess antimicrobial properties, are produced by a vas...

introduction: candida dubliniensis and c. albicans are very similar in morphology and phenotypic characteristics. approximation of this yeast species has caused major problems in identifying these two correctly. materials and methods: to distinguish among sixty yeast clinical isolates from patients with cancer, polymerase chain reaction - restriction fragment length polymorphism (pcr-rflp) was ...

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...

Background and Purpose: Trichosporon is a genus of anamorphic basidiomycetous yeast which is widely distributed in nature and is found in tropical and temperate areas. The aim of this work was to study the isolation, identification and molecular analysis of Trichosporon species in soil. Materials and Methods: In order to isolate and identify Trichosporon species in soil, 30 samples were collec...

The increasing incidence of candidiasis and antifungal resistance as well as the introducing of new antifungal has recently encouraged performing of fungal susceptibility testing. The aim of this study was to evaluate the susceptibility profile of Candida species isolated from patients admitted to Yazd central laboratory to fluconazole. We used the broth microdilution method to evaluate the sus...

Lichens are symbiotic partnerships between a filamentous fungus and photosymbiotic “alga”. Studies show that lichens harbor endothallic fungi, but some taxa have been difficult to isolate from the main thallus-forming other faster growing lichenicolous/endothallic fungi. Therefore, we aimed develop evaluate liquid yeast-enrichment strategies (1) lichen-associated yeasts in pure culture, (2) det...
