Kikuchi W, Noguchi A, Sato Y, Konno Y, Komatsu A, Tandai S, et al.
Viruses . 2024 Nov; 16(11). PMID: 39599872
Rotavirus vaccines carry a small risk of intussusception mainly 1-7 days after vaccination in the United States of America, Europe, Australia, and Latin America where the background rate of intussusception...

Viruses . 2024 Oct; 16(10). PMID: 39459863
Most human rotaviruses belong to the Wa-like, DS-1-like, or AU-1-like genotype constellation. The AU-1-like constellation, albeit minor, captured attention because its prototype strain AU-1 originated from feline rotavirus, leading to...

Hoa-Tran T, Nakagomi T, Vu H, Nguyen T, Dao A, Nguyen A, et al.
Virus Evol . 2024 Jul; 10(1):veae045. PMID: 38952820
Animal rotaviruses A (RVAs) are considered the source of emerging, novel RVA strains that have the potential to cause global spread in humans. A case in point was the emergence...

Kadoya S, Urayama S, Nunoura T, Hirai M, Takaki Y, Kitajima M, et al.
Front Microbiol . 2022 Jun; 13:839513. PMID: 35668760
RNA virus populations are not clonal; rather, they comprise a mutant swarm in which sequences are slightly different from the master sequence. Genetic diversity within a population (intrapopulation genetic diversity)...

Kadoya S, Urayama S, Nunoura T, Hirai M, Takaki Y, Kitajima M, et al.
J Virol . 2020 Mar; 94(10). PMID: 32132235
RNA viruses form a dynamic distribution of mutant swarms (termed "quasispecies") due to the accumulation of mutations in the viral genome. The genetic diversity of a viral population is affected...

Hoa-Tran T, Nakagomi T, Vu H, Nguyen T, Takemura T, Hasebe F, et al.
Infect Genet Evol . 2020 Jan; 80:104194. PMID: 31931261
A rapid increase and dominance of G9P[8] Rotavirus A strains occurred in northern Vietnam between 2016 and 2018, during which period there appeared three G9P[8] strains possessing short RNA patterns....

Emerg Infect Dis . 2019 Aug; 25(9):1734-1737. PMID: 31441761
Atypical DS-1-like G1P[8] rotaviruses emerged in 2013 in Malawi after rotavirus vaccine introduction. Vaccine effectiveness among infants hospitalized with acute DS-1-like G1P[8] rotavirus gastroenteritis was 85.6% (95% CI 34.4%-96.8%). These...

PLoS One . 2019 Jun; 14(5):e0217422. PMID: 31150425
Recent increase in the detection of unusual G1P[8], G3P[8], G8P[8], and G9P[4] Rotavirus A (RVA) strains bearing the DS-1-like constellation of the non-G, non-P genes (hereafter referred to as the...

Infect Genet Evol . 2019 Apr; 73:1-6. PMID: 30978460
While conducting rotavirus gastroenteritis surveillance in Vietnam, two G3P[8] rotavirus A specimens possessing an identical short RNA electropherotype were detected. They were RVA/Human-wt/VNM/0232/2016/G3P[8] and RVA/Human-wt/VNM/0248/2016/G3P[8], and recovered from 9 and...

Front Microbiol . 2019 Feb; 10:38. PMID: 30766516
A comprehensive molecular epidemiological study using next-generation sequencing technology was conducted on 333 rotavirus A (RVA)-positive specimens collected from six sentinel hospitals across Japan over three consecutive seasons (2012-2014). The...
