Group B rotaviruses detected in Bangladesh in 2000 and 2001 were analyzed genetically to clarify relatedness to human group B rotaviruses reported previously in China and India, and to animal group B rotaviruses. VP7 gene sequences of the Bangladeshi group B rotaviruses (Bang373, Bang544, Bang334, and Bang402) were almost identical to each other and also showed high sequence identity to the Indian strain CAL‐1 (98%) and Chinese strain adult diarrhea rotavirus (ADRV) (92%), while identities to… 
Phylogenetic analysis of a human group B rotavirus WH‐1 detected in China in 2002
The sequence divergence between WH‐1 and ADRV was estimated as 7.9 × 10−4 substitution/site per year, suggesting that the group B rotaviruses of Indian–Bangladeshi lineage diverged from that of Chinese lineage several decades ago.
Whole genomic characterization of a human rotavirus strain B219 belonging to a novel group of the genus rotavirus
The basic structures of all B219 viral proteins are considered to be similar to those of the known rotavirus groups.
Analysis of genetic diversity and molecular evolution of human group B rotaviruses based on whole genome segments.
Divergent or conserved regions in the deduced amino acid sequences of GBR VP1-VP4 and NSP1-NSP5 were similar to those in group A rotaviruses (GARs), and the functionally important motifs and structural characteristics in viral proteins known for GAR were conserved in all of the human GBRs.
Detection of group B rotavirus in an adult with acute gastroenteritis in Yangon, Myanmar
Although the deduced amino acid sequences of MMR‐B1 were similar to those of strains CAL‐1 and Bang373, several amino acids in VP8* were found to be different from those of the group B rotavirus described previously.
Evidence for Occurrence of Human group B rotavirus in Central India Based on Characterization of NSP2 Gene
It is indicated that MP-1 isolate might have originated from a common ancestral HuGBR virus but distinct from AnGBR lineage, and is closer to Bangladeshi (Bang373) as compared to Indian strain (CAL-1).
Molecular characterization of a human group C rotavirus detected first in Turkey
The present study found that the Turkish group C rotavirus was unique and can serve as an additional reference strain for the molecular epidemiology of group CRotavirus in children with diarrhea presented at two major hospitals in Ankara, Turkey.

Diversity in VP3, NSP3, and NSP4 of rotavirus B detected from Japanese cattle.
The Genome Segments of a Group D Rotavirus Possess Group A-Like Conserved Termini but Encode Group-Specific Proteins
The first complete genome sequence of a group D rotavirus is presented, which was amplified using sequence-independent amplification strategies and degenerate primers and the nucleotide sequences at the termini of the 11 genome segments are identical between group D and group A rotaviruses.


Sequence analysis of genes encoding structural and nonstructural proteins of a human group B rotavirus detected in Calcutta, India
It is suggested that human group Brotavirus CAL‐1 and ADRV might have originated from a common ancestral virus distinct from animal group B rotaviruses reported so far, while some notable sequence differences indicated the distinct nature of these viruses.
First detection of bovine group B rotavirus in Japan and sequence of its VP7 gene
The Nemuro strain is the first report on the presence of bovine group B rotavirus in Japan and the identities of the nucleotide (nt) and deduced amino acid (aa) sequences of the Nemuro VP7 gene were high and low compared to those of the published corresponding genes from 3 bovines and 2 other mammalian (human and rat) strains of group Brotaviruses.
The complete nucleic acid sequence of gene segment 3 of the IDIR strain of group B rotavirus.
This work sequenced the entire third genomic segment of the IDIR strain of GBR and found that hybridization with IDIR gene 3 clones permitted detection of heterologous GBR strains, and synthetic polypeptides deduced from portions of the gene 3 nucleic acid sequence cross-reacted with anti-GBR antibody.
An outbreak of epidemic diarrhoea in adults caused by a new rotavirus in anhui province of China in the summer of 1983
This study indicates the new virus can be identified as part of a new group of rotaviruses and has been incriminated as the causative agent of the epidemic in Shexian County of Anhui Province in 1983.
Sequence of the fourth gene of human rotaviruses recovered from asymptomatic or symptomatic infections
There is conservation of arginine at the two trypsin cleavage sites as well as conservation of clusters of amino acids in different regions of the two VP3 cleavage products, VP8 and VP5, among nine human rotavirus VP3 genes that have been sequenced.
First report of an epidemic of diarrhoea in human neonates involving the new rotavirus and biological characteristics of the epidemic virus strain (KMB/R85)
It was found that KMB/R85 strain did not possess the common group antigen shared by group A rotaviruses and was antigenically similar to the Chinese adult diarrhoea rotavirus (serogroup B).
Sequence conservation within neutralization epitope regions of VP 7 and VP 4 proteins of human serotype G 4 rotavirus isolates
The characteristic periodicity of occurrence of serotype G 4 isolates causing severe diarrhoea in Melbourne children is unlikely to be due to changes in neutralization epitopes located on the outer capsid proteins, VP 7 or VP 4.

The outer capsid protein VP4 of murine rotavirus strain Eb represents a tentative new P type.
It appears that the Eb strain should be considered a new VP4 genotype and/or serotype after antisera to recombinant VP4s of five distinct rotavirus serotypes and two subtypes failed to react significantly by neutralization assay with the Eb strains.
Detection of group B rotaviruses in fecal samples from diarrheic calves and adult cows and characterization of their VP7 genes
Although there were some differences of degree, all inoculated gnotobiotic calves showed abnormal feces between 1 and 3 days after inoculation with each of three strains of group B bovine rotaviruses, and group B rotavirus, were detected in the feces for up to 2 weeks by RT-PCR but for shorter periods by PAGE or IEM.
