Fluorescent biological aerosol particles in residence

Residences represent an important site for bioaerosol exposure because of the large proportion of time that people spend in their homes. Using real-time instrumentation, our recent study in Indoor Air investigated bioaerosol concentrations, emissions, and exposures in a northern California residence, focusing on the effect of human occupancy and activities. Using an ultraviolet aerodynamic particle …

Evolution happens: Bacteria becoming resistant to hospital disinfectants

Well, if true this is both troubling and not surprising: Bacteria becoming resistant to hospital disinfectants, warn scientists | Society | The Guardian The story reports on a paper in Science Translational Medicine. Some quotes: The results reveal that Enterococcus faecium bacteria have become more tolerant to alcohol over that time. “We found that the new …

This air resistance is a real drag: global survey of antibiotic resistance genes in air samples

This new open access paper from Li et al may be of interest. Global Survey of Antibiotic Resistance Genes in Air.   Abstract: Despite its emerging significant public health concern, the presence of antibiotic resistance genes (ARGs) in urban air has not received significant attention. Here, we profiled relative abundances (as a fraction, normalized by 16S rRNA …

How important is hand-washing outside of a hospital environment?

I recently spent a weekend visiting a friend out of state and quickly came to realize that he rarely washed his hands. Before eating? No. After the gym? No. Even after going to the bathroom…and not just urination. No washing! I was disgusted and could not convince him of the same. How could an educated …
