Plants and animals may serve as excellent hosts for many fungi. Spores from fungi (molds) are primarily spread by water and air and come into contact with plants in the field or with grain in storage facilities. Factors that influence the degree of fungal infestation in grain are moisture, temperature and availability of oxygen. Other factors such as insect population, physical condition of gra...

  Fungal infection in the eggs of freshwater fish is well known as a problematic disease. The aim of the present study was to isolate and identify parasitic and saprophytic fungi from affected eggs of rainbow trout at two fish hatchery in Kermanshah province. The sample were inoculated in culture media (SDA,CMA,GPA and stilled water with cotton seed culture) at room temperature (18-24 ° C).17 s...

Demodex spp may cause blepharitis and palpebra skin lesions. Since eyelash demodicosis seems to be quite spreadable in the community, every patient with chronic non-diagnosed blepharitis should be examined for Demodex spp. Tea tree oil treatment may be an efficient and safe therapeutical choice against ocular demodicosis.

Symbiotic associations between different organisms are of great importance for evolutionary and ecological processes [1-4]. Bacteria are particularly valuable symbiotic partners owing to their huge diversity of biochemical pathways that may open entirely new ecological niches for higher organisms [1-3]. Here, we report on a unique association between a new Streptomyces species and a solitary hu...

Mycotoxins are toxic secondary metabolites produced by several fungi species growing on many agricultural commodities and processed foods (Bennett & Klich, 2003). The term secondary metabolite designates compounds that are not indispensable for the growth and metabolism of the fungi as such, and in contrast to primary metabolites, such as amino acids, fatty acids, saccharides, nucleic acids and...

The Experiments were carried out during the period of July 2001 to December 2002. Infestation of poultry feeds by fungi and aflatoxins content in feeds were determined. Ten feed samples were collected from ten different farms located in three different areas of Bangladesh. Five different fungal species belonging four genera were detected which were Aspergillus flavus, Aspergillus niger, Fusariu...

Beech bark disease (BBD) results in high levels of initial mortality, leaving behind survivor trees that are greatly weakened and deformed. The disease is initiated by feeding activities of the invasive beech scale insect, Cryptococcus fagisuga, which creates entry points for infection by one of the Neonectria species of fungus. Without scale infestation, there is little opportunity for fungal ...

Herbivory, mechanical injury or pathogen infestation to vegetative tissues can induce volatile organic compounds (VOCs) production, which can provide defensive functions to injured and uninjured plants. In our studies with 'McNeal' wheat, 'Otana' oat, and 'Harrington' barley, plants that were mechanically injured, attacked by either of two Oulema spp. (melanopus or cyanella) beetles, or infecte...
