A series of incidents involving damage to vehicle speed sensor cables occurred in an urban area in Japan. At the request of the police, DNA analysis was conducted to identify the animal species responsible. Swab samples collected from the damaged sections of the cables were subjected to PCR testing using mtDNA fragments. Sequencing analysis with universal primers (SCPH02500, SCPL02981) detected DNA from the Japanese marten (). A comprehensive examination that included morphological analysis of the cable damage and consideration of the ecological characteristics of the Japanese martens suggested that the damage was likely caused by this species. DNA analysis using mtDNA markers is a valuable tool for species identification in wildlife forensic veterinary investigations and serves as important scientific evidence in criminal cases involving animals. The findings from this case may contribute to future investigations in forensic veterinary science and ecological research and may also inform measures to prevent human-wildlife conflicts involving animals.
日本某市区发生了一系列车辆速度传感器电缆受损事件。应警方要求，进行了DNA分析以确定肇事动物物种。从电缆受损部位采集的拭子样本使用线粒体DNA片段进行了PCR检测。使用通用引物（SCPH02500、SCPL02981）进行的测序分析检测到了日本貂（Martes melampus）的DNA。一项综合检查，包括对电缆损伤的形态分析以及对日本貂生态特征的考量，表明这种损伤很可能是由该物种造成的。使用线粒体DNA标记进行DNA分析是野生动物法医兽医调查中物种鉴定的宝贵工具，也是涉及动物的刑事案件中的重要科学证据。该案例的研究结果可能有助于未来法医兽医学调查和生态研究，也可为预防涉及动物的人类与野生动物冲突的措施提供参考。
