This study aimed to determine the aerosolization behavior of a nanodispersion of budesonide, prepared using microfluidic reactors. The size and morphology of budesonide nanoparticles were characterized by photon correlation spectroscopy (PCS) and transmission electron microscopy (TEM). Processing/formulation parameters for formation of the nanoparticles were studied to determine their effects o...

Antibiotic resistance poses a threat in many institutions including hospitals, meat processing facilities and other agricultural occupational entities. The goal of this research is to uncover how bacteria react environmental conditions aerosolization delineate factors that trigger expression antibiotic genes (ARGs) using the laboratory strain Escherichia coli (E. coli) MG 1655 as surrogate bact...

We report here that stress experienced by bacteria due to aerosolization and air sampling can result in severe membrane impairment, leading to the release of DNA as free molecules. Escherichia coli and Bacillus atrophaeus bacteria were aerosolized and then either collected directly into liquid or collected using other collection media and then transferred into liquid. The amount of DNA released...

Bioaerosol research often requires stable and reliable aerosol generators that could produce high particle concentrations. However, there is still a lack of information about the effect of aerosolization on the physiological status of microorganisms. Here we tested the performance of several liquid bioaerosol generators including a Collison nebulizer, a LiquidSparging Aerosolizer (LSA), a C-flo...

BACKGROUND Noroviruses are responsible for at least 50% of all gastroenteritis outbreaks worldwide. Noroviruses GII can infect humans via multiple routes including direct contact with an infected person, fecal matter, or vomitus, and contact with contaminated surfaces. Although norovirus is an intestinal pathogen, aerosols could, if inhaled, settle in the pharynx and later be swallowed. The aim...

To determine whether aerosolization could impair bacterial survival, Pseudomonas syringae and Erwinia herbicola were aerosolized in a greenhouse, the aerosol was sampled at various distances from the site of release by using all-glass impingers, and bacterial survival was followed in the impingers for 6 h. Bacterial survival subsequent to aerosolization of P. syringae and E. herbicola was not i...
