| analysis of rotavirus species diversity and evolution including the newly determined full-length genome sequences of rotavirus f and g. | rotaviruses are a leading cause of viral acute gastroenteritis in humans and animals. eight different rotavirus species (a-h) have been defined based on antigenicity and nucleotide sequence identities of the vp6 gene. here, the first complete genome sequences of rotavirus f (strain 03v0568) and g (strain 03v0567) with lengths of 18,341 and 18,186bp, respectively, are described. both viruses have open reading frames for rotavirus proteins vp1 to vp7 and nsp1 to nsp5 located at the 11 genome segme ... | 2013 | 23237956 |
| detection of the vp6 gene of group f and g rotaviruses in broiler chicken fecal samples from the amazon region of brazil. | the aim of this study was to detect rotavirus f (rvf) and rotavirus g (rvg) in fecal specimens of broiler chickens in brazil. during 2008 and 2011, a total of 85 fecal samples were collected. the viral genome was extracted, followed by polyacrylamide gel electrophoresis (page), reverse transcription polymerase chain reaction (rt-pcr), and nucleotide sequencing. samples were screened for rotaviruses by page, and rvf and rvg genome banding patterns were not seen. using rt-pcr, it was found that 9. ... | 2016 | 27154557 |
| description of rotavirus f in broilers from brazilian poultry farms. | rotaviruses are segmented double-stranded rna viruses that cause gastroenteritis in mammals and birds. here we describe the first partial nucleotide sequences of the structural protein vp6 from the genomes of group f rotaviruses that were detected in 5 out of 53 fecal samples (9.43%) from healthy broilers from brazilian poultry farms based on reverse-transcriptase-pcr with primers designed for this study. the findings support the development of molecular detection systems, which can be used for ... | 2014 | 25518442 |
| metagenomic characterisation of additional and novel avian viruses from australian wild ducks. | birds, notably wild ducks, are reservoirs of pathogenic and zoonotic viruses such as influenza viruses and coronaviruses. in the current study, we used metagenomics to detect and characterise avian dna and rna viruses from wild pacific black ducks, chestnut teals and grey teals collected at different time points from a single location. we characterised a likely new species of duck aviadenovirus and a novel duck gyrovirus. we also report what, to the best of our knowledge, is the first finding of ... | 2020 | 33335272 |
