Three dipeptides, belonging to the family of diketopiperazines (DKPs), were extracted from broth culture of the grapevine endophyte Alternaria alternata, and were tested against Plasmopara viticola on leaves of grapevine plants grown in greenhouse. DKPs, used at different concentrations (10(-3), 10(-4), 10(-5) and 10(-6)M) both singularly and in mixtures, demonstrated real effectiveness in inhi...

Carrot seed oil is the source of the carotane sesquiterpenes carotol, daucol and beta-caryophyllene. These sesquiterpenic allelochemicals were evaluated against Alternaria alternata isolated from the surface of carrot seeds cultivar Perfekcja, a variety widely distributed in horticultural practise in Poland. Alternaria alternata is one of the most popular phytotoxic fungi infesting the carrot p...

Leaf spot and blight disease was observed on two-year-old seedlings of Dendropanax morbifera (Korean name: Hwangchil tree) during July of 2008 in Jindo Island, Korea. Symptoms included yellow-brown to dark brown irregularly enlarged spots frequently located along the veins of leaves. The lesions were often surrounded by chlorotic haloes. Severe leaf blight and subsequent defoliation occurred wh...

Nine indole derivatives were evaluated in vitro against Fusarium graminearum, Alternaria alternata, Helminthosporium sorokinianum, Pyricularia oryzae, Fusarium oxysporum f. sp. vasinfectum, Fusarium oxysporum f. sp. cucumarinum, and Alternaria brassicae. Most of the compounds were found to possess antifungal activities. Especially compounds 2, 5, 8, and 9 exhibited broad-spectrum antifungal act...

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)....

Species of Aspergillus, Penicillium and Alternaria are major contributors to fruit and vegetable decay and to mycotoxin production during various stages of pathogenesis. The mycotoxins most commonly associated with fruits and vegetables and their products are aflatoxins, patulin, ochratoxin A and Alternaria toxins. Naturally occurring aflatoxins are found in fruits of tropical and subtropical r...

Objectives: To determine the isolation rate of Alternaria alternata in patients with clinical Onychomycosis Study Design: Descriptive (cross sectional) study Place and Period of Study: Department of Microbiology, Armed Forces Institute of Pathology Rawalpindi, from August 2011-April 2012. Material and Methods: Sample size; 200 nail samples, Sampling Technique; Non probability convenience sampli...

PURPOSE The AdvanSure™ AlloScreen assay is an advanced multiplex test that allows for simultaneous detection of specific IgE (sIgE) against multiple allergens. For precise identification of causative allergens in allergic patients, we compared this new multiplex sIgE assay with the ImmunoCAP assay, which is currently the gold-standard method for sIgE detection. MATERIALS AND METHODS Serum sam...

Sensitivity to the fungus Alternaria is associated with asthma persistence and severity. Current therapeutic options for treating Alternaria-induced airway inflammation are limited. In this study, Brown Norway rats are used to study the effectiveness of a DNA-based vaccine delivered to the airway in attenuating the response to a major Alternaria allergen, rAlt a 2. Compared to untreated sensiti...
