Alternaria brown spot is one of the most important diseases of tangerines and their hybrids worldwide. Recently, outbreaks in Mediterranean areas related to susceptible cultivars, refocused attention on the disease. Twenty representatives were selected from a collection of 180 isolates of Alternaria spp. from citrus leaves and fruit. They were characterized along with reference strains of Alter...

Humid indoor environments may be colonised by allergenic filamentous microfungi (moulds), Aspergillus spp., Penicillium spp., Cladosporium spp., and Alternaria spp. in particular. Mould-induced respiratory diseases are a worldwide problem. In the last two decades, mould allergens and glucans have been used as markers of indoor exposure to moulds. Recently, mould allergens Alt a 1 (Alternaria al...

Introduction Jujube (Ziziphus mauritiana Lam.) tree is subjected to attack by different fungal pathogens causing various diseases. In India, powdery mildew (Oidium sp.) causes defoliation and fruit-drop. Sooty mold (Cladosporium zizyphi) causes leaves to fall. Leaf spot results from infection by Cercospora spp. and Isariopsis indica var. zizyphi. Leaf rust, caused by Phakopsora zizyphi-vulgaris...

Background and Aims: The study aimed to determine the effectiveness of three medicinal plant extracts on fungi with three methods and to compare methods. Material and methods: This study examined the antifungal properties of cumin (Cuminum cyminum L), ginger (Zingiber officinale Roscoe) and Nafe Venus (Umbilicus intermedius boiss) extracts against fungi including, Aspergillus spp., Penicillium...

Introduction and objective: Detection of the common allergen airborne fungi in any region is critical for prevention and treatment of allergic fungal diseases. Therefore, this study was conducted to identify the most common airborne fungal species of Isfahan, investigate their allergic reactions in animal and obtain local fungal strains for use as antigens in allergy tests to be used. Materials...

conclusions alternariasis or similar cases may be increased due to the increased number of immunosuppressed patients. from this point of view, skin lesions in these patients must be planned and microbiologically evaluated considering the molds. case presentation we reported a case of wound infection induced by alternaria spp. in a renal transplant patients. the main interest in this case was th...

The aim of this study was to determine the accuracy of monoclonal antibodies (mAbs) in identifying culturable allergenic fungi present in visible mould growth in energy efficient homes, and to identify risk factors for exposure to these known allergenic fungi. Swabs were taken from fungal contaminated surfaces and culturable yeasts and moulds isolated by using mycological culture. Soluble antig...

The antifungal activity of N-chlorotaurine (NCT), a long-lived oxidant produced by stimulated human leucocytes, was investigated. Incubation of Aspergillus spp., Candida spp., Fusarium spp., Penicillium spp. and Alternaria spp. in 1% NCT (55 mM) for 1-4 h produced a log10 reduction in cfu of between 1 and 4. In samples of nasal secretion, killing was significantly hastened (30 min), which may b...

Sexual reproduction in heterothallic ascomycete fungi is controlled by a single mating-type locus called MAT1 with two alternate alleles or idiomorphs, MAT1-1 and MAT1-2. These alleles lack sequence similarity and encode different transcriptional regulators. A large number of phytopathogenic fungi including Alternaria spp. are considered asexual, yet still carry expressed MAT1 genes. The molecu...

The objective of this study was to evaluate biotic interaction between some mould species and active producer of aflatoxin B1 Aspergillus flavus NRRL 3251, co-cultured in yeast-extract sucrose (YES) broth. Twenty-five mould strains of Alternaria spp., Cladosporium spp., Mucor spp., A. flavus and A. niger, used as biocompetitive agents, were isolated from outdoor and indoor airborne fungi, scrap...
