This on-site survey study was performed to determine the concentrations and emissions of aerial contaminants in the different types of swine houses in Korea and then to present beneficial information available for Korean pig producers to manage optimal air quality in swine house. The swine houses investigated in this research were selected based on three criteria; manure removal system, ventila...

Bioaerosol concentrations in office environments and their roles in causing building-related symptoms have drawn much attention in recent years. Most bioaerosol studies have been cross-sectional. We conducted a longitudinal study to examine the characteristics of airborne fungal populations and correlations with other environmental parameters in office environments. We investigated four office ...

A population survey of 1000 7 year old children found a significant excess of wheeze among children whose homes were reported to be mouldy (odds ratio 3.70, 95% confidence limits 2.22, 6.15). The airborne mould flora was quantified by repeated volumetric sampling during the winter in three rooms of the homes of 88 children. All of these had previously completed spirometric tests before and afte...

The aim of this study was to evaluate effects of microbial aerosols on immune function of ducks and shed light on the establishment of microbial aerosol concentration standards for poultry. A total of 1800 1-d-old cherry valley ducks were randomly divided into five groups (A, B, C, D, and E) with 360 ducks in each. To obtain objective data, each group had three replications. Concentrations of a...

A new developed dustfall collector has been investigated which collects airborne dust by sedimentation. The dustfall collector was placed at least 1.5 m above the floor. It was made of cardboard and the collecting surface was covered with aluminium foil; a chicken wire covered the box. After 140 days the dust was collected using the VacuMark sampler. Bioaerosols were sampled three times during ...

Investigations in the airborne mycoflora of Karachi was carried out using Spore Trapper technique along with culture media Petri plate technique. In order to collect different types of airborne fungal spores, five sites were selected for installing the spore trappers. In the course of collected spores, different types of fungal spores were identified. The study revealed that the fungal spores w...

The aerobiology of caves in Southern Spain possesses special characteristics, different from located Northern Spain. Previous studies demonstrated the influence outdoor air on north and existence two patterns, depending season. In summer there is an abundance Ascomycota, whereas winter Basidiomycota predominates, which are related to periods stagnation ventilation, respectively. presence airbor...

PURPOSE Chronic rhinosinusitis with nasal polyps is a chronic inflammatory disease with markedly increased eosinophils, Th2-type lymphocytes, fibroblasts, and goblet cells. Fungi are commonly associated with airway inflammatory diseases, and thymic stromal lymphopoietin (TSLP) is important in the development of Th2 inflammatory responses. The aim of this study was to investigate the interaction...

BACKGROUND Exposure to airborne fungi has been related with exacerbation of asthma in adults and children leading to increased outpatient, emergency room visits, and hospitalizations. Hypersensitivity to these airborne fungi may be an important initial predisposing factor in the development and exacerbation of asthma. OBJECTIVE This study was conducted to determine an association between fung...

INTRODUCTION Atmospheric air is the most common vehicle for the dispersion of fungi. Fungi belonging to the genera Aspergillus and Penicillium are cosmopolitan and are classified in the family Trichocomaceae. Species of the genera are commonly found in soil, decaying organic materials, animal feed, stored grains, and other materials. This study aimed to determine the taxonomic diversity of airb...
