“…In mammals, astroviruses adapted to the new hosts and there is no record of documented interspecies transmission in recent times [17,18]. The increasing number of novel distinct astroviruses described in mammalian species in recent years seems to confirm this hypothesis [19][20][21][22][23][24][25][26].…”

Genetic characterization of astroviruses detected in guinea fowl (Numida meleagris) reveals a distinct genotype and suggests cross-species transmission between turkey and guinea fowl

et al. 2012

Astroviruses can infect mammalian and avian species and are often responsible for gastroenteric disease symptoms. In this study, the complete open reading frame (ORF) 2, the 3' end of ORF1b and the corresponding intergenic region of astroviruses identified in farmed guinea fowl (Numida meleagris) were sequenced and genetically analysed. Overall, the genetic sequence of guinea fowl astroviruses was related to turkey astrovirus type 2 (TastV2), although a marked genetic distance was revealed based on ORF2, which might indicate the circulation of a distinct virus genotype and serotype in guinea fowl. Furthermore, the genetic data presented herein suggest that either recombination between different astroviruses infecting distinct hosts or adaptation of a given astrovirus to a new host had occurred. In either case, direct or indirect interspecies transmission of astroviruses is likely to have occurred between turkey and guinea fowl, indicating the ability of viruses belonging to the family Astroviridae to cross species barriers.

“…We failed to amplify region I of the canine AstV ORF2, which has a relatively low nucleotide sequence variability when compared with region II (central region of the capsid protein precursor) [20], by using another set of primers (501F20 and 1156R21) [21]. This result is in agreement with Castro et al, who could not amplify this ORF2 region with this set of primers from two Brazilian strains detected in 2012 that were positive for ORF1b (strains RJ1109 and RJ1110) [22].…”

“…Since 2009, a few reports have identified AstV in canine diarrhea cases in Italy, China, France, Brazil and South Korea [17][18][19][20][21][22][23], showing high variability at the nucleotide and amino acid levels in the capsid region. We failed to amplify region I of the canine AstV ORF2, which has a relatively low nucleotide sequence variability when compared with region II (central region of the capsid protein precursor) [20], by using another set of primers (501F20 and 1156R21) [21].…”

Sewage surveillance reveals the presence of canine GVII norovirus and canine astrovirus in Uruguay

et al. 2015

Canine norovirus (NoV) and astrovirus (AstV) were studied in 20 domestic sewage samples collected in two cities in Uruguay. Four samples were characterized as canine AstV after phylogenetic analysis clustering with strains detected in Italy and Brazil in 2008 and 2012, respectively. One sample was characterized as canine NoV and clustered with a strain detected in Hong Kong and recently classified as GVII. This study shows the occurrence of a canine NoV GVII strain for the first time in the American continent and also warns about possible zoonotic infection, since canine strains were detected in domestic sewage.

“…Such a severe clinical picture could be easily attributed to other canine pathogens (CPV-2 or CCoV) by veterinarians. Surveys in Italy and China have revealed differences in AstV distribution between symptomatic (12.0 to 24.5%) and asymptomatic (0 to 9.3%) animals (12,22). Overall, these findings suggest that AstVs may play a role as enteric pathogens of dogs.…”

Enteric Disease in Dogs Naturally Infected by a Novel Canine Astrovirus

et al. 2012

View full text Add to dashboard Cite

Infection by a novel canine astrovirus was associated with gastroenteritis in two dogs. The virus displayed 70.3 to 73.9% amino acid identity to other canine astroviruses in the full-length capsid. Specific antibodies were detected in the convalescent-phase sera of the dogs, indicating seroconversion. Also, the virus appeared weakly related antigenically to the prototype canine astrovirus isolate ITA/2008/Bari.
