The genus Alternaria has more than 80 species. Alternaria alternata and Alternaria infectoria are the most frequent species associated with infections in humans. Their clinical importance lies in the growing number of cases reported in immunocompromised patients. Herein, we report three cases of kidney-transplanted patients with different clinical presentations of cutaneous alternariosis and we...

Purpose. Alternaria spp. are an uncommon cause of mycotic keratitis. Previous studies on Alternaria keratitis have generally been limited to case reports. We examined the clinical characteristics of Alternaria keratitis in this study. Methods. The characteristics and outcomes of 7 patients with culture-proven Alternaria keratitis treated in our hospital were compared with 25 previously reported...

To advance our understanding of the molecular biochemistry fungi which impact cultural heritage in libraries, museums and archives we investigated diagnostic capacity Raman spectroscopy to identify composition colored chromophores on paper. In this study explored resonant distinguish fungal filaments stimulated grow paper under high humidity with a focus characterizing Alternaria group species....

A new semi-selective medium, acidified weak potato-dextrose agar (AWPDA) with Mertect (active ingredient: thiabendazole), was developed for the isolation and enumeration of Alternaria species from samples of soil and plant debris. The medium was selected based on growth inhibition tests against Alternaria and several other commonly encountered saprobic fungi utilizing three antifungal agents, B...

A common consequence of using agricultural fungicides is the development of resistance by fungal pathogens, which undermines reliability of fungicidal effectiveness. A potentially new strategy to aid in overcoming or minimizing this problem is enhancement of pathogen sensitivity to fungicides, or "chemosensitization." Chemosensitization can be accomplished by combining a commercial fungicide wi...

Using trans-diphenylpropane oxide (tDPPO) as a substrate, we measured epoxide hydrolase (EH) activity in subcellular fractions of Alternaria alternata f. sp. lycopersici (Aal), a fungus that produces host-specific toxins. The activity was mainly (> 99.5%) located in the soluble fraction (100,000 x g supernatant) with the optimum pH at 7.4. An increase of toxin production between days 3 and 9 fo...

BACKGROUND : The aim of this study is to investigate relationships between fungal colonization in the house and IgE sensitization to fungi, and to clarify the effects of house care in relation to fungi. MATERIALS AND METHODS : We measured levels of fungi in the houses of 52 allergic children. Of these, 32 children displayed detectable levels of IgE (≥0.35 UA/ml) to a combination of fungi (pos...

The sphinganine analog mycotoxin, AAL-toxin, induces a death process in plant and animal cells that shows apoptotic morphology. In nature, the AAL-toxin is the primary determinant of the Alternaria stem canker disease of tomato, thus linking apoptosis to this disease caused by Alternaria alternata f. sp. lycopersici. The product of the baculovirus p35 gene is a specific inhibitor of a class of ...

Mycotoxins are toxic food pollutants that created naturally by some fungus. By contaminating food, they have a harmful impact on human health. This study's major objective was to simulate products from bakeries being contaminated. Separate bakery samples were examined see whether fungus and associated mycotoxins present. One hundred fifty-nine (159) collected randomly different shops in rural s...
