A genome of a virus preliminarily named avian gyrovirus 2 (AGV2), a close relative to chicken anemia virus, was recently discovered in a chicken in the state of Rio Grande do Sul, Southern Brazil. To study the occurrence of AGV2 in Rio Grande do Sul and the neighboring state Santa Catarina, a number of adult chickens (n=108 and n=48, respectively) were tested for the presence of AGV2 DNA. An AG...
Avian gyrovirus 2 (AGV2) was the second member of the viral genus Cyclovirus to be discovered. This virus poses a significant potential threat to humans and poultry due to its global dissemination and infectiousness. We used three overlapping polymerase chain reactions (PCRs) to map the whole genome of AGV2. We then modelled the evolutionary history of these novel sequence data in the context o...
Introduction. Chicken anaemia virus, CAV, was until recently the only member of the Gyrovirus genus. 6 novel gyroviruses, AGV2, HGyV1, and GyV3-6, have since been discovered in human and chicken samples. Methods. PCR amplification of the VP2 gene was used to detect AGV2/HGyV1, GyV3, and CAV in a range of clinical samples including stool, respiratory, CSF, and HIV-positive plasma. Screening of f...
The chicken anemia virus (CAV), is a known member of the genus Gyrovirus and was first isolated from chickens in Japan in 1979. Some reports have also demonstrated that CAV can be identified in human stool specimens. In this study, a variant of CAV was detected using PCR with CAV-based primers in fecal samples of stray cats. The genome of CAV variant was sequenced and the results suggest that i...
The genus Gyrovirus was assigned to the family Anelloviridae in 2017 with only one recognized species, Chicken anemia virus. Over last decade, many diverse viruses related chicken virus have been identified but not classified. Here, we provide a framework for classification of new species and communicate establishment nine species. We adopted ‘Genus + freeform epithet’ binomial system naming th...
In 2013, studies conducted on human clinical samples in Vietnam and Malawi indicated for the first time that cycloviruses might be associated with central nervous system infection in humans. A definitive causal link to neurological diseases was not established and would require further studies. Cycloviruses belong to the Circoviridae family together with the genera circovirus and gyrovirus. The...
