| Outline of Final Research Achievements |
We explored detectability of infecting viral genes from forensic sample including swab and organ by applying rapid determination system of viral RNA/DNA sequences (RDV). We detected genes of feline calicivirus and feline herpesvirus from throat and nasal cavity swab samples of autopsied cat by the RDV method, and then we rapidly identified these viruses by PCR and direct sequence of PCR product. To measure the impact of postmortem change on viral genes contained in organ, we performed quantitative PCRs that amplify a variety of lengths of influenza virus gene. As the result, it suggested the possibility that influenza virus genes were broken in the lung sample of the infected mouse. Therefore, it was deemed desirable to use a comparatively short fragment amplified by the RDV method in the case of detection of virus gene from organ sample.
