| Outline of Final Research Achievements |
In this study, we demonstrated in vivo molecular imaging of virus-infected mice. We inoculated encephalitis viruses (Japanese encephalitis virus and Tick-borne encephalitis virus), Severe fever with thrombocytopenia virus (SFTSV) and newly isolated Nairovirus (TFLV) in each susceptible mouse. Following encephalitis virus infections, decrease of 18F-FDG uptakes were observed in the brains of virus-infected mice compared with mock-infected mice. On the other hand, following infections with SFTSV and TFLV, significant uptakes of 18F-FDG were observed in the small intestines of virus-infected mice but not in mock-infected mice. These data will provide useful information for further study of molecular imaging in the field of virology.
