BACKGROUND Fungal allergy is considered as serious health problem worldwide and is increasing at an alarming rate in the industrialized areas. Rhizopus oyzae is a ubiquitously present airborne pathogenic mold and an important source of inhalant allergens for the atopic population of India. Here, we report the biochemical and immunological features of its 44 kDa sero-reactive aspartic protease a...

The purpose of this study was to describe the prevalence of respiratory symptoms and skin prick test findings in a group of 383 employees in a plant bakery population who had the greatest regular exposure to ingredient dusts. The prevalence of positive skin prick tests to fungal amylase was 16%, in contrast to 6% to wheat flour, suggesting that the principal sensitiser is fungal amylase and not...

The Aspergillus fumigatus mouse model of asthma mimics the characteristics of human fungal asthma, including local and systemic inflammation. Monocyte/macrophage lineage cells direct innate immune responses and guide adaptive responses. To identify gene expression changes in peripheral blood monocytes in the context of fungal allergy, mice were exposed to systemic and intranasal inoculations of...

Alternaria alternata spores are considered a well-known biological contaminant and a very common potent aeroallergen source that is found in environmental samples. The most intense exposure to A. alternata allergens is likely to occur outdoors; however, Alternaria and other allergenic fungi can colonize in indoor environments and thereby increase the fungal aeroallergen exposure levels. A conse...

our aim in this study was to identify and characterize allergic proteins in cooked wolf herring fish. we heated the crude extract alternatively at 50, 60, 70, 80, 90, and 100°c for one hour and results were compared by sodium dodecyl sulfate polyacrylamide gel electrophoresis (sds-page). also, proteins were immunoblotted with fish-sensitive patients’ sera. the major allergenic proteins were ide...

background: allergy is a clinical disorder affecting humans worldwide. allergenic extracts prepared from natural source materials remain heterogeneous in composition and content, but are regularly used for diagnosis and immunotherapy. recombinant allergens are suitable candidates to use in place of natural allergens; however, the recombinant allergens should be assessed and compared with the na...

INTRODUCTION The complicated etiology of chronic sinusitis with polyps and frequent allergy to mould is established. AIM We aimed to investigate the frequency of the IgE-dependent hypersensitivity in this group of patients and prove the need of surgery in allergic chronic rhinosinusitis patients. MATERIAL AND METHODS Forty-two patients (19 females, 23 males) aged 34-73 years (55 ±12.6 years...

OBJECTIVE This study investigated allergic fungal rhinosinusitis cases, and aimed to compare the detection of fungi in sinus aspirate by culture and by polymerase chain reaction assay, and to relate the presence of fungi in the nasal sinuses to the type of fungal allergen causing disease. METHODS Sixty-eight cases of allergic fungal rhinosinusitis underwent fungal culture and polymerase chain...

Asthma, a common disorder that affects >250 million people worldwide, is defined by exaggerated bronchoconstriction to inflammatory mediators including acetylcholine (ACh), bradykinin and histamine-also termed airway hyper-responsiveness. Nearly 10% of people with asthma have severe, treatment-resistant disease, which is frequently associated with immunoglobulin-E sensitization to ubiquitous fu...
