    The common degu (<i>Octodon degus</i>), originally native to South America, is now widely used as an experimental animal owing to several unique characteristics: common degus are highly social and use vocal sounds as communication tools. Importantly, their brain function is more complex than other laboratory rodents, making them a good model in the field of neuroscience. We established a colony of laboratory common degus and observed epilepsy-like seizures. We subsequently analyzed the process, strength, and duration of seizures by video recording. We examined 35 video images from 16 individuals (7 females and 9 males). The seizures began as abnormalities in the body parts (step 1), and then systemic tonic-clonic seizure (step 2) was observed. Following step 2, a short period of stillness (step 3) usually occurred, and then systemic tonic seizure occurred again (step 4). Ultimately, stillness (step 5) continued until recovery. We found sex-based differences in the strength and duration of seizures and observed large individual differences as well. Our results suggest that common degus have the potential to be used as a disease model for epilepsy.

    © 2019 Japanese Association for Laboratory Animal Science. The Asian house shrew, Suncus murinus, is an insectivore (Eulipotyphla, Mammalia) and an important laboratory animal for life-science studies. The gastrointestinal tract of Suncus is simple: the length of the entire intestine is very short relative to body size, the large intestine is quite short, and there are no fermentative chambers such as the forestomach or cecum. These features imply that Suncus has a different nutritional physiology from those of humans and mice, but little is known about whether Suncus utilizes microbial fermentation in the large (LI) or small (SI) intestine. In addition, domestication may affect the gastrointestinal microbial diversity of Suncus. Therefore, we compared the gastrointestinal microbial diversity of Suncus between laboratory and wild Suncus and between the SI and LI (i.e., four groups: Lab-LI, Lab-SI, Wild-LI, and Wild-SI) using bacterial 16S rRNA gene library sequencing analyses with a sub-cloning method. We obtained 759 cloned sequences (176, 174, 195, and 214 from the Lab-LI, Lab-SI, Wild-LI, and Wild-SI samples, respectively), which revealed that the gastrointestinal microbiota of Suncus is rich in Firmicutes (mostly lactic acid bacteria), with few Bacteroidetes. We observed different bacterial communities according to intestinal region in laboratory Suncus, but not in wild Suncus. Furthermore, the gastrointestinal microbial diversity estimates were lower in laboratory Suncus than in wild Suncus. These results imply that Suncus uses lactic acid fermentation in the gut, and that the domestication process altered the gastrointestinal bacterial diversity.

    生息環境の変化に直面した動物は、自身がもつ適応形質から現況に適したものを判断し発現しなければ生残できない。しかしその判断は往々にして一様でなく、同種でも個体・集団のレベルでばらつきが見られる。こうした動物の意思決定の違いが何に起因するのかは殆ど分かっていない。これまでに申請者は、小型哺乳類の適応形質のひとつ「休眠」に着目し、その発現頻度が成熟したひと腹の兄妹内で異なること、更にその個体差が離乳以前に生じる「兄妹内の競争」に起因することを示唆してきた。本研究では胎仔期及び乳仔期の兄妹関係の詳細を明らかにし、これらが動物の意思決定と適応形質の進化に対し、どのように関係してきたのかについて考察する。
