asthma is a complicated disorder, whose prevalence has increased over the past few decades.asthma is characterized by infiltration of inflammatory leukocytes along with enhancedproinflammatory cytokines and chemokines. fungi are now far more widely being considered as thedominant extrinsic trigger for asthma. fungi are linked to the severity of asthma in many ways. somedifferences between studi...

Specific oligonucleotide probes were developed to identify medically important fungi that display yeast-like morphology in vivo. Universal fungal primers ITS1 and ITS4, directed to the conserved regions of ribosomal DNA, were used to amplify DNA from Histoplasma capsulatum, Blastomyces dermatitidis, Coccidioides immitis, Paracoccidioides brasiliensis, Penicillium marneffei, Sporothrix schenckii...

The clinical management of a patient with systemic fungus infection is dependent upon so many different factors that no single form of therapy can be recommended for any one mycosis. Because of variations in response to different types of therapy, the clinical course must be the chief guide in the treatment of each patient. It is the purpose of this paper to present immunologic data obtained in...

Several fungi can assume either a filamentous or a unicellular morphology in response to changes in environmental conditions. This process, known as dimorphism, is a characteristic of several pathogenic fungi, e.g., Histoplasma capsulatum, Blastomyces dermatitidis, and Paracoccidioides brasiliensis, and appears to be directly related to adaptation from a saprobic to a parasitic existence. H. ca...

Sequence data from mitochondrial and nuclear small subunit rDNA were used to estimate phylogenetic relationships of cantharelloid and clavarioid Homobasidiomycetes. Sixty-five diverse Homobasidiomycete species were investigated, including 23 cantharelloid and clavarioid species. Although nodes deep in the tree could not be resolved, four lineages containing cantharelloid and clavarioid fungi we...

While it is generally acknowledged that orchid species rely on mycorrhizal fungi for completion of their life cycle, little is yet known about how mycorrhizal fungal diversity and community composition vary within and between closely related orchid taxa. In this study, we used 454 amplicon pyrosequencing to investigate variation in mycorrhizal communities between pure (allopatric) and mixed (sy...

We determined whether in vitro plant growth regulator production by mycorrhizal fungi is correlated with conifer seedling growth and root IAA concentrations. Container-grown seedlings of interior Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), lodgepole pine (Pinus contorta Dougl.) and ponderosa pine (Pinus ponderosa Dougl.) were inoculated at seeding with ectomycorrhizal fungi having a hig...

Oral microbiota is one of the most complex and diverse microbial communities in the human body. In the present study, we aimed to characterize oral fungi biodiversity and stability over time in a group of healthy participants with good oral health. Oral health and oral fungal microbiota were evaluated in 40 healthy individuals. A follow-up of 10 participants was carried out 28 weeks and 30 week...

conclusions the presence of fungi in the nasal cavity and indoors of healthy subjects in this study suggests that fungi should be considered as health hazards. furthermore, it is important and seems necessary to monitor indoor air quality and raise awareness of existing threats due to microorganisms, including fungi. results the most common fungi isolated from all samples were aspergillus, peni...
