| vp6 gene diversity in 11 brazilian strains of porcine group c rotavirus. | porcine group c rotavirus (rvc) is recognised as an enteric pathogen in piglets worldwide. the vp6 gene of rvc is divided into seven i-genotypes. genotypes i2 and i3 are found in human and bovine strains, respectively; the porcine strains are divided into the other five genotypes (i1, i4-i7). in this study, molecular analysis of nearly the full length of the vp6 gene was performed in 11 brazilian wild-type porcine rvc strains identified in diarrhoeic faecal samples, which were collected from eig ... | 2015 | 25331342 |
| nucleotide correlations between rotavirus c isolates in clinical samples from outbreaks and in sewage samples. | rotavirus c (rvc) is detected in both sporadic cases and outbreaks of gastroenteritis worldwide. however, the epidemic dynamics of rvc in populations remain poorly understood because the detection rate is low. in this study, raw sewage samples were collected from a wastewater treatment plant in yokohama, japan, over 5 years, in 12-month period from september to august, to identify the rvc strains in these samples and compare them with the rvc strains circulating in the population. rvc strains we ... | 2015 | 25475764 |
| genetic analysis of human rotavirus c: the appearance of indian-bangladeshi strain in far east asian countries. | rotaviruses c (rvcs) circulate worldwide as an enteric pathogen in both humans and animals. most studies of their genetic diversity focus on the vp7 and vp4 genes, but the complete genomes of 18 human rvcs have been described in independent studies. the genetic background of the far east asian rvcs is different than other human rvcs that were found in india and bangladesh. recently, a rvc detected in 2010 in south korea had genetic background similar to the indian-bangladeshi rvcs. this study wa ... | 2016 | 27071530 |
| detection of enteric viruses in fecal specimens from nonbacterial foodborne gastroenteritis outbreaks in tokyo, japan between 1966 and 1983. | we investigated the prevalence of 5 enteric viruses (norovirus [nov], sapovirus, rotavirus, astrovirus, and adenovirus) in archived stool specimens collected from 70 foodborne gastroenteritis outbreaks in tokyo, japan, which occurred from 1966 to 1983, and genetically characterized these viruses. nov was detected in 48 (68.6%) outbreaks, while sav, group c rotavirus (rvc), and astrovirus were detected in 1 (1.4%) outbreak each. based on the partial capsid sequences, the detected novs were classi ... | 2017 | 27357976 |

| prevalence of rotaviruses groups a and c in egyptian children and aquatic environment. | the objective of this study is to compare the prevalence of rotaviruses groups a and c in egyptian children and aquatic environment. from 110 stool specimens of children with acute diarrhea and using rt-pcr, 35 samples (31.8 %) were positive for human rotavirus group a and 15 samples (13.6 %) were positive for human rotavirus group c. from 96 samples collected from zenin wastewater treatment plant over a 2-year period (november 2009-october 2011) and using rt-pcr, rotavirus group a was detected ... | 2015 | 25665825 |
| modeling of the rotavirus group c capsid predicts a surface topology distinct from other rotavirus species. | rotavirus c (rvc) causes sporadic gastroenteritis in adults and is an established enteric pathogen of swine. because rvc strains grow poorly in cell culture, which hinders generation of virion-derived rvc triple-layered-particle (tlp) structures, we used the known rotavirus a (rva) capsid structure to model the human rvc (bristol) capsid. comparative analysis of rva and rvc capsid proteins showed major differences at the vp7 layer, an important target region for vaccine development due to its an ... | 2016 | 26524514 |
| genetic heterogeneity of the vp6 gene and predominance of g6p[5] genotypes of brazilian porcine rotavirus c field strains. | the aim of this study was to investigate the genetic diversity of the vp6, vp7, and vp4 genes of 15 brazilian wild-type porcine rvc strains identified in diarrheic fecal samples. the vp6 gene analysis demonstrated heterogeneity between the 15 rvc strains, which clustered in three distinct genotypes (i1, i5, and i6). in the vp7 and vp4 gene analysis, the genotype combination g6p[4] was detected in only one strain (uel-77), while g6p[5] was the most commonly (n = 14) detected in rvc strains identi ... | 2016 | 26758732 |
| characterization of a genetically heterogeneous porcine rotavirus c, and other viruses present in the fecal virome of a non-diarrheic belgian piglet. | next-generation sequencing (ngs) technologies are becoming increasingly accessible, leading to an expanded interest in the composition of the porcine enteric virome. in the present study, the fecal virome of a non-diarrheic belgian piglet was determined. although the virome of only a single piglet was analyzed, some interesting data were obtained, including the second complete genome of a pig group c rotavirus (rvc). this belgian strain was only distantly related to the only other completely cha ... | 2016 | 27184192 |
