Research has demonstrated that swine feed can be a fomite for viral transmission and additives reduce contamination. Therefore, the objective of this study was to evaluate two in contaminated with PEDV or PRRSV. Feed included: no treatment, 0.33% commercial formaldehyde-based product, 0.50% medium chain fatty acids (MCFA) blend. samples were inoculated PRRSV alone together at an inoculation con...

Nowadays, most experiments to synthesize and test photocatalytic antimicrobial materials are based on trial error. More often than not, the mechanism of action activity is unknown for a large spectrum microorganisms. Here, we propose scheme speed up design optimization surfaces tailored give balanced production reactive oxygen species (ROS) upon illumination. Using an experiment-to-machine-lear...

We review recent studies on fomite transmission of COVID-19, caused by the novel coronavirus. In particular, we focus survival time coronavirus solid and porous surfaces. Since aqueous phase a respiratory droplet serves as medium for virus survival, evaporation surface plays crucial role in determining time. While bulk takes few seconds to evaporate, previous titer measurements revealed that ca...

Microbial contamination of plastic surfaces is a significant source hospital-acquired infections. To produce antimicrobial surfaces, chlorhexidine was attached to nitrided acrylonitrile butadiene styrene (ABS). The uniformity distribution on the revealed by time-of-flight secondary ion mass spectrometry (TOF-SIMS) imaging. Its efficacy established against model pathogenic Gram-positive and Gram...

Introduction: Many SARS-CoV-2 variants of concern (VOC) have been reported recently that were linked to increased transmission. In our earlier study using VOC 202012/01 (U.K. variant) and D614G variant in the hamster model, we observed higher viral RNA shedding through nasal wash case U.K. with lower pathogenicity lung. this study, studied transmission these two by direct contact, aerosol, fomi...

Although ambient temperature has diverse effects on disease dynamics, few studies have examined how temperature alters pathogen transmission by changing host physiology or behaviour. Here, we test whether reducing ambient temperature alters host foraging, pathology and the potential for fomite transmission of the bacterial pathogen Mycoplasma gallisepticum (MG), which causes seasonal outbreaks ...

The growing prevalence of multidrug-resistant bacteria poses a unique challenge to animal and human health. The threat of nosocomial infections in hospitals and infectious outbreaks in vivaria through fomites requires novel technological solutions. We describe the use of a compact device capable of producing a disinfecting air stream based on electrical plasma-induced chemistry and hydrogen per...
