Broadly Reactive and Highly Sensitive Assay for Norwalk-Like Viruses Based on Real-Time Quantitative Reverse Transcription-PCR
Tsutomu Kageyama,Shigeyuki Kojima,Michiyo Shinohara,Kazue Uchida,Shuetsu Fukushi,Fuminori B. Hoshino,Naokazu Takeda,Kazuhiko Katayama +7 more
TL;DR: An assay for the detection of Norwalk-like viruses (NLVs) based on reverse transcription-PCR (RT-PCRs) that is highly sensitive to a broad range of NLVs and can be used as a routine assay for diagnosis as well as for elucidation of the epidemiology of NLV infections.
Journal ArticleDOI

TL;DR: It is shown that a TMPRSS2-expressing VeroE6 cell line is highly susceptible to Sars-CoV-2 infection, making it useful for isolating and propagating SARS-Cov-2.
Journal ArticleDOI
Genogroup-specific PCR primers for detection of Norwalk-like viruses.
Shigeyuki Kojima,Tsutomu Kageyama,Shuetsu Fukushi,Fuminori B. Hoshino,Michiyo Shinohara,Kazue Uchida,Katsuro Natori,Naokazu Takeda,Kazuhiko Katayama +8 more
TL;DR: Improved primer sets based on the capsid region, to detect both genogroups I and II NLV by genogroup-specific manner, were developed and were extremely useful for the amplification and rapid diagnosis of nonbacterial gastroenteritis due to NLV as well as for epidemiological studies.

TL;DR: There was continuous circulation in east and Southeast Asia via a region-wide network of temporally overlapping epidemics and that epidemics in the temperate regions were seeded from this network each year, suggesting that once A (H3N2) viruses leave E-SE Asia, they are unlikely to contribute to long-term viral evolution.
Journal ArticleDOI
Coexistence of Multiple Genotypes, Including Newly Identified Genotypes, in Outbreaks of Gastroenteritis Due to Norovirus in Japan
Tsutomu Kageyama,Michiyo Shinohara,Kazue Uchida,Shuetsu Fukushi,Fuminori B. Hoshino,Shigeyuki Kojima,Reiko Takai,Tomoichiro Oka,Naokazu Takeda,Kazuhiko Katayama +9 more
TL;DR: The molecular epidemiology of NV was investigated from 66 outbreaks that occurred in Saitama Prefecture, Japan, from 1997 to 2002, and a total of 31 genotypes were identified, including an additional five genotypes for genogroup I and seven for Genogroup II.
