Sensitivity Analysis of , and by Irradiation with Far-UVC, UVC, and UVB.

Background: The World Health Organization has published a list of pathogenic fungi with prior-itizing groups and calls for research and development of antifungal measures, with belonging to the group with high priority.

Methods: The photosensitivity towards short wavelength ultraviolet irradiation (Far-UVC, UVC, and UVB) was investigated and compared to other yeasts () and a mold (). The observed 1-log reduction doses were compared to literature values of other representatives of the genus , but also with and .

Fungal photoinactivation doses for UV radiation and visible light-a data collection.

Nearly two million people die each year from fungal infections. Additionally, fungal crop infections jeopardize the global food supply. The use of 254 nm UVC radiation from mercury vapor lamps is a disinfection technique known to be effective against all microorganisms, and there are surveys of published UVC sensitivities.

Photoinactivation by UVA radiation and visible light of Candida auris compared to other fungi.

In addition to the rising number of patients affected by viruses and bacteria, the number of fungal infections has also been rising over the years. Due to the increase in resistance to various antimycotics, investigations into further disinfection options are important. In this study, two yeasts (Candida auris and Saccharomyces cerevisiae) and a mold (Cladosporium cladosporioides) were irradiated at 365, 400, and 450 nm individually.

Radiative transfer equation-based color prediction and color adjustment strategies.

This paper discusses different strategies for color prediction and matching. Although many groups use the two-flux model (i.e.

Sensitivity of influenza virus to ultraviolet irradiation.

Background: The measures implemented against the coronavirus pandemic also led to a sharp decline in influenza infections in the 2020/2021 flu season. In the meantime, however, the number of influenza infections has risen again; it is known from history that influenza viruses can also trigger severe pandemics. Therefore, we investigated the efficacy of ultraviolet radiation in the spectral range of 200-400 nm for inactivating influenza viruses.

Investigation on Potential ESKAPE Surrogates for 222 and 254 nm Irradiation Experiments.

Background: Due to the increase in multidrug-resistant pathogens, it is important to investigate further antimicrobial options. In order not to have to work directly with pathogens, the investigation of possible surrogates is an important aspect. It is examined how suitable possible surrogate candidates for ESKAPE pathogens are for UVC applications.
