Environmental or city-scale bioaerosol surveillance can provide additional value for biodefense and public health. Efficient bioaerosol monitoring should rely on multiplex systems capable of detecting a wide range of biologically hazardous components potentially present in air (bacteria, viruses, toxins and allergens). xMAP technology from LuminexTM allows multiplex bead-based detection of anti...

Greenhouse operations are an important sector of the horticulture industry, also known as the Green Industry, accounting for nearly 2 million US jobs and about $148 billion in output. It is a work environment that can result in increased exposure to respiratory hazards because of its fundamentally enclosed nature. In addition, high concentrations of bioaerosols may be aerosolized by work activi...

A microchannel-based aerosol size separator that separates submicron aerosols according to particle inertial differences and Dean vortices in the airflow was developed for use in low-cost, portable, real-time aerosol collectors, detectors, concentrators and other such devices. The microfluidic inertial separator was furthermore applied to simultaneously separate airborne microorganisms by size,...

Actinobacteria are widely distributed in many environments and represent the most important trigger to the occupant respiratory health. Health complaints, including hypersensitivity pneumonitis of the workers, were recorded in a mushroom compost facility (MCF). The studies on the airborne bacteria were carried out to find a possible microbiological source of these symptoms. Culture analysis of ...

The feasibility of using a novel detection scheme for the analysis of biological warfare agents is demonstrated using Bacillus globigii spores, a surrogate species for Bacillus anthracis. In this paper, a sensitive and selective enzyme-linked immunosorbent assay using a novel fluorogenic alkaline phosphatase substrate (dimethylacridinone phosphate) is combined with a compact biochip detection s...

There is a global trend toward intensive livestock breeding, which tends to increase the microbial load in environment as well presence of volatile compounds and dust that can cause health issues. Cattle major producer Escherichiacoli (E. coli), group foodborne bacteria associated with severe human diseases, Neuquén province Argentina has one highest rates uremic hemolytic syndrome incidence wo...

Studying the fluid dynamics of exhalations, from droplet formation to turbulent cloud transport, is vital for understanding respiratory disease transmission. Our research combines experiments and numerical modeling uncover interfacial phenomena involved in bioaerosol generation during forceful breathing actions like coughing or sneezing. By investigating these fluid-mechanical processes, we aim...
