1185 Abstract The etiologic significance of Aspergillus fumigatus, a saprobic organism, has been described in a young pigeon which died due to severe respiratory distress. The fungus was easily demonstrated in the pneumonic lung both by cultural isolation as well as direct microscopy. The bird was kept in captivity and was given mouldy feed. Epidemiological investigation revealed the high conce...

Aspergillus fumigatus is the most common and life-threatening aerial fungal pathogen, especially among immunocompromised hosts. Understanding the pathobiology of this pathogen requires investigations both to characterise the immunosuppressive status of the phagocytic cells that usually kill the fungus in the immunocompetent host, and to identify fungal virulence factors that either promote the ...

Invasive aspergillosis is characterized by hyphal invasion of the blood vessels, which contributes to the pathogenesis of this disease. During this angioinvasion, Aspergillus fumigatus interacts with the endothelial cell lining of the blood vessels. We investigated the response of vascular endothelial cells to A. fumigatus infection in vitro and in mouse models of invasive pulmonary aspergillos...

FR227244 is a novel triterpene glycoside that exhibits in vitro antifungal activity against filamentous fungi such as Aspergillus sp. and Trichophyton sp. and yeast such as Candida utilis and Candida parapsilosis but shows low activity against Candida albicans, Candida krusei and Candida tropicalis. Specifically, FR227244 exhibits in vitro and in vivo antifungal activity against Aspergillus fum...

The objective of the present study was to isolate fungi from agricultural soils and evaluate fungal growth in culture medium contaminated with atrazine, glyphosate pendimethalin. Filamentous were isolated cultured a modified containing 0, 10, 20, 50, 100 ?g mL-1 pendimethalin for 14 days at 28°C. that presented optimal satisfactory plated Sabouraud 4% dextrose herbicides concentrations seven me...

Aspergilloma and invasive aspergillosis are important opportunistic infections caused by Aspergillus species, among which Aspergillus fumigatus is the most common species associated with human disease. We developed an enzyme-linked immunosorbent assay (ELISA)-based antibody assay with Afmp1p, a purified recombinant antigenic cell wall galactomannoprotein of A. fumigatus. Evaluation of the test ...

BACKGROUND IgG and IgG subclass antibodies to Aspergillus fumigatus (A fumigatus) were measured in a large population of patients with cystic fibrosis to elucidate a putative antibody pattern specific for allergic bronchopulmonary aspergillosis (ABPA). METHODS An ELISA technique using water soluble somatic hyphal (WSSH) A fumigatus antigens and subclass specific monoclonal antibodies was used...

Invasive aspergillosis is a leading cause of infectious death in immunosuppressed patients. Here, we adapted a phage display library-based selection to screen and identify binding peptides to the surface of Aspergillus fumigatus conidia and hyphae. We identified a peptide (sequence CGGRLGPFC) that reliably binds to the surface of Aspergillus fumigatus hyphae. Binding was not Aspergillus strain ...

Aspergillus species are globally ubiquitous saprophytes found in a variety of ecological niches. Almost 200 species of aspergilli have been identified, less than 20 of which are known to cause human disease. Among them, Aspergillus fumigatus is the most prevalent and is largely responsible for the increased incidence of invasive aspergillosis (IA) in the immunocompromised patient population. IA...

Toll-like receptors mediate macrophage recognition of microbial ligands, inducing expression of microbicidal molecules and cytokines via the adapter protein MyD88. We investigated the role of MyD88 in regulating murine macrophage responses to a pathogenic yeast (Candida albicans) and mold (Aspergillus fumigatus). Macrophages derived from bone marrow of MyD88-deficient mice (MyD88(-/-)) demonstr...
