Feline coronavirus (FCoV) is classified into two biotypes based on its pathogenicity in cats: a feline enteric coronavirus of low pathogenicity and a highly virulent feline infectious peritonitis virus. It has been suspected that FCoV alters its biotype via mutations in the viral genome. The S and 3c genes of FCoV have been considered the candidates for viral pathogenicity conversion. In the present study, FCoVs were analyzed for the frequency and location of mutations in the S and 3c genes from faecal samples of cats in an animal shelter and the faeces, effusions, and tissues of cats that were referred to veterinary hospitals. Our results indicated that approximately 95% FCoVs in faeces did not carry mutations in the two genes. However, 80% FCoVs in effusion samples exhibited mutations in the S and 3c genes with remainder displaying a mutation in the S or 3c gene. It was also suggested that mutational analysis of the 3c gene could be useful for studying the horizontal transmission of FCoVs in multi-cat environments.

中田喜直の生涯での作品は3000曲に近いといわれる。多くの作品が日本人の愛唱歌として親しまれている。本論では晩年に作曲された、金子みすゞ童謡歌曲集"ほしとたんぽぽ"を考察し、金子みすゞの童謡詩(14 作品)は童謡としてではなく歌曲として作曲されているのか、その音楽の真髄を探る。
