The Effect of Enzymatic and Viability Dye Treatment in Combination with Long-Range PCR on Assessing Tulane Virus Infectivity
J Virol Methods. 2024 Mar 24:114919. doi: 10.1016/j.jviromet.2024.114919. Online ahead of print.ABSTRACTHuman norovirus (HuNoV) is regularly involved in food-borne infections. To detect infectious HuNoV in food, RT-qPCR remains state of the art but also amplifies non-infectious virus. The present study combines pre-treatments, RNase and propidium monoazide, with three molecular analyses, including long-range PCR, to predominantly detect infectious Tulane virus (TuV), a culturable HuNoV surrogate. TuV was exposed to inactivating conditions to assess which molecular method most closely approximates the reduction in infectiou...

Recovery and Quantification of Norovirus in Air Samples from Experimentally Produced Aerosols
AbstractNorovirus is the leading cause of acute gastroenteritis in humans across all age groups worldwide. Norovirus-infected patients can produce aerosolized droplets which play a role in gastroenteritis transmission. The study aimed to assess bioaerosol sampling in combination with a virus concentrating procedure to facilitate molecular detection of norovirus genogroup (G) II from experimentally contaminated aerosols.  Using a nebulizer within an experimental chamber, aerosols of norovirus GII were generated at known concentrations. Air samples were then collected in both 5 mL and 20 mL water using the SKC BioSampler ...
