Student thesis: Bachelor


Norovirus causes winter vomiting disease and is one of the commonest cause of winter illness in Sweden. The disease period generally lasts one to three days with symptoms like vomiting and/or diarrhea. To the disease burden of acute gastroenteritis worldwide, norovirus contributes with 18 %. Even though the illness is very common, the knowledge about norovirus is poor and largely unknown.The purpose of the study was to do a time series analysis, a so-called One-Step Growth analysis, of the minus-RNA concentration in cells infected with different concentrations of murine norovirus (MNV). For the detection of minus-RNA RT-qPCR was used with SYBR Green. The goal was to correlate start concentration of virus at any time with the amount of minus-RNA in the cells. At 4 and 8 hours there was an exponential connection by the initial virus concentration and minus-RNA development in the cells. The concentration of minus-RNA in the infected cells increased between 4, 8 and 24 hours. Further, the results can be interpreted as requiring 4 hours for the higher concentrations to become quantifiable, while requiring 24 hours for the lower concentrations to become quantifiable.
