BACKGROUND Massive die-offs of little brown bats (Myotis lucifugus) have been occurring since 2006 in hibernation sites around Albany, New York, and this problem has spread to other States in the Northeastern United States. White cottony fungal growth is seen on the snouts of affected animals, a prominent sign of White Nose Syndrome (WNS). A previous report described the involvement of the fung...
In efforts to record pathogenic fungal diversity on ornamental plants of Pakistan, infected leaves Chlorophytum comosum were collected from commercial nursery in Lahore, Pakistan. Investigation leafspot symptoms led identification an ascomycete fungus, Thielavia terrestris. Analysis for involved morphological, microscopic and molecular methods. ITS-nrDNA sequence data used construct phylogeneti...
Dimorphism or morphogenic conversion is exploited by several pathogenic fungi and is required for tissue invasion and/or survival in the host. We have identified a homolog of a master regulator of this morphological switch in the plant pathogenic fungus Fusarium oxysporum f. sp. lycopersici. This non-dimorphic fungus causes vascular wilt disease in tomato by penetrating the plant roots and colo...
The study was conducted for the purpose of knowing effect mycorrhizal fungus on controlling root rot disease caused by pathogenic Rhizoctonia solani, field experiment included four treatments and each treatment had five replicates, were as follows (Control, Mycorrhiza, Rhizoctonia, Rhizoctonia), where percentage infection with (0.00, 0.00, 96.91, 63.58), respectively. while growth indicators st...
In the search for bioactive compounds, 11 fungal strains were isolated from Indonesian marine habitats. Ethyl acetate extracts of their culture broth were tested for cytotoxic activity against a urinary bladder carcinoma cell line and for antifungal and antibacterial activities against fish and human pathogenic bacteria as well as against plant and human pathogenic fungi. The crude extract of a...
Tuber melanosporum is an ectomycorrhizal ascomycete producing edible ascocarps. The prevalent view is that this species strictly selfs, since genetic analyses have never detected heterozygotic profiles in its putatively diploid/dikaryotic gleba. The selfing model has also forged the experimental approaches to assess the population genetic variability. Here, the hypothesis that T. melanosporum o...
background: colibacillosis is one of the most prevalentdiseases in the world that causes multimillion-dollar annuallosses. objectives: in order to evaluate molecular epidemiologyof some virulence associated factors in escherichia coli,isolated from poultry, the presence of iut a, iss, hly f, omp t, iron, afa, sfa (s)and pap g (ii) were investigated by multiplex pcrassay. methods: two hundred th...
The ability of the pathogenic fungus Cryptococcus neoformans to cause life-threatening meningoencephalitis in immunocompromised individuals is due in large part to elaboration of a capsule consisting of polysaccharide fibers. The size of the cell-associated capsule is remarkably responsive to a variety of environmental and host conditions, but the mechanistic details of the regulation, synthesi...
