Purple blotch, caused by Alternaria porri (Ellis) Cifferi, is a serious disease incurring heavy yield losses in the bulb and seed crop of onion and garlic worldwide. There is an immediate need for identification of effective resistance sources for use in host resistance breeding. A total of 43 Allium genotypes were screened for purple blotch resistance under field conditions. Allium cepa access...

A total of 394 (255 males,139 females) live freshwater crayfish Astacus leptodactylus from four stations of Aras reservoir in West Azarbaijan Province (North-Western Iran) were studied during the winter until early autumn of 2009 for the presence of parasites, Epibionts and Fungal agents. Parasitological surveys were carried out on gills exoskeleton and internal organs, mycological examinations...

Sensitization and exposure to the allergenic fungus Alternaria alternata has been associated with increased risk of asthma and asthma exacerbations. The first cells to encounter inhaled allergens are epithelial cells at the airway mucosal surface. Epithelial barrier function has previously been reported to be defective in asthma. This study investigated the contribution of proteases from Altern...

Two new compounds isobenzofuranone A (1) and indandione B (2), together with eleven known compounds (3-13) were isolated from liquid cultures of an endophytic fungus Alternaria sp., which was obtained from the medicinal plant Morinda officinalis. Among them, the indandione (2) showed a rarely occurring indanone skeleton in natural products. Their structures were elucidated mainly on the basis o...

Plant growth-promoting rhizobacteria (PGPR) are advantageous bacteria that inhabit around plant roots and enhance plant growth by a wide variety of direct and indirect mechanisms. Utilization of PGPR is now gradually increasing in agriculture and offers an attractive way to replace chemical fertilizers, pesticides, and supplements. In our present study six endospore forming bacterial isolates t...

In an epidemiological inquiry on 126 dogs and 24 cats, the most frequent dermatomycosis was microsporia. The following fungi species were identified: Microsporum canis, M. gypseum, Trichophyton mentagrophytes, T. concentricum, Malassezia pachidermatis, Candida albicans, Alternaria sp., Aspergillus sp., Penicilium sp. The dermatophytes were identified not only on the animal body, but also on the...

Endophytic fungi are inhabitants of plants, living most part of their lifecycle asymptomatically which mainly confer protection and ecological advantages to the host plant. In this present study, 48 endophytic fungi were isolated from the leaves of three medicinal plants and characterized based on ITS2 sequence - secondary structure analysis. ITS2 secondary structures were elucidated with minim...

Abstract A study of antifungal properties violacein-forming strain Janthinobacterium sp. B-3515 as well its secondary metabolite, violacein, against Alternaria brassicicola F-1864 is presented. Regardless the presence bacteria, mycelium growth in first two days proceeded at same rate. The effect bacterial was manifested after third day incubation. In general, during co-culture, statistically si...

BACKGROUND AND OBJECTIVE Given the importance of rapid diagnosis for fungal rhinosinusitis, this study aimed to evaluate the use of nested PCR to identify Aspergillus and Mucor species in clinical samples from patients with suspected fungal rhinosinusitis. METHODS Functional endoscopic sinus surgery specimens were collected from 98 patients with rhinosinusitis from 2012 to 2013. All samples w...
