| feline fecal virome reveals novel and prevalent enteric viruses. | humans keep more than 80 million cats worldwide, ensuring frequent exposure to their viruses. despite such interactions the enteric virome of cats remains poorly understood. we analyzed a fecal sample from a single healthy cat from portugal using viral metagenomics and detected five eukaryotic viral genomes. these viruses included a novel picornavirus (proposed genus "sakobuvirus") and bocavirus (feline bocavirus 2), a variant of feline astrovirus 2 and sequence fragments of a highly divergent f ... | 2014 | 24793097 |
| environmental assessment of classical human astrovirus in uruguay. | the aim of this study was to determine the molecular epidemiology of classical human astrovirus (hastv) strains in sewage samples from four uruguayan cities: bella unión, salto, paysandú, and fray bentos, located in the northwestern region of the country. overall, 96 sewage samples were collected biweekly between march 2011 and february 2012 and were subject to ultracentrifugation methodology in order to concentrate the viruses. rt-pcr directed to the orf2 genome region was performed followed by ... | 2015 | 25680829 |
| propagation of astrovirus va1, a neurotropic human astrovirus, in cell culture. | astrovirus va1/hmo-c (va1; mamastrovirus 9) is a recently discovered astrovirus genotype that is divergent from the classic human astroviruses (mamastrovirus 1). the gastrointestinal tract is presumed to be the primary site of infection and pathogenicity for astroviruses. however, va1 has been independently detected in brain tissue of five cases of human encephalitis. studies of the pathogenicity of va1 are currently impossible because there are no reported cell culture systems or in vivo models ... | 2017 | 28701405 |
