Mathematical Modeling for Evaluating Inherent Parameters Affecting UVC Decontamination of Indicator Bacteria.

UV light is a tool associated with the denaturation of cellular components, DNA damage, and cell disruption. UV treatment is widely used in the decontamination process; however, predicting a sufficient UV dose by using traditional methods is doubtful. In this study, an in-house UVC apparatus was designed to investigate the process of the inactivation of five indicator bacteria when the initial cell concentrations and irradiation intensities varied.

The phylodynamics of emerging porcine deltacoronavirus in Southeast Asia.

Porcine deltacoronavirus (PDCoV), a recently emerging pathogen, causes diarrhoea in pigs. A previous phylogenetic analysis based on spike genes suggested that PDCoV was divided into three different groups, including China, the United States, and Southeast Asia (SEA). SEA PDCoV, however, is genetically separated from China and the United States but shares a common ancestor.
