SUMMARY Circovirus infections have been documented in adult and nestling canaries (Fringillidae) but the distribution of the virus in the world is not yet known. In captive canary flocks, Circovirus infections have been reported based on the clinical observations. In this study, the presence of both canary circovirus (CaCV) and chicken anemia virus (CAV) in canary flocks was investigated. Virus strains were detected by PCR and direct sequencing of amplified products. Nucleotide sequences were… 
Chlamydiosis in a Gouldian Finch (Erythrura gouldiae)
The first report of avian chlamydiosis with hepatic viral particles consistent with circovirus infection in a Gouldian finch is reported, suggesting a role of these avian species as important carriers.
Monitored Therapy of Sporadic Mycobacteriosis Caused By Mycobacterium Genavense in Atlantic Canaries (Serinus Canaria) and Bengalese Finch (Lonchura Striata)
Canary circovirus and polyomavirus co-infection may suppress the immune system and this may facilitate the development of mycobacteriosis.

Detection and phylogenetic characterization of Columbid circoviruses in Chaharmahal va Bakhtiari province, Iran
This is the first report of molecular detection and genomic characterization of PiCV from Iran and Phylogenetic analysis has grouped the viruses with those classified as group A circoviruses.
Molecular characterization of novel circoviruses from finch and gull
Nucleotide sequence determination and analysis of cloned genomic DNAs showed that these circoviruses represented novel members of the genus Circovirus of the family Circoviridae, and have been tentatively named Finch circovirus (FiCV) and Gull Circov virus (GuCV).
Epidemiological investigation and genome analysis of duck circovirus in Southern China
Molecular epidemiological data suggest there is no obvious difference among DuCV strains isolated from different geographic locations or different species, including Duck, Muscovy duck, Mule duck, Cheery duck, Mulard duck and Pekin duck.
Nucleotide sequence-based identification of a novel circovirus of canaries
Sequence analysis of a 510 nucleotide genomic fragment indicated that canary circovirus (CCV) represents a new avian virus of the genus Circovirus of the family Circoviridae, and is more closely related to CoCV than BFDV.
Detection of pigeon circovirus in cloacal swabs: implications for diagnosis, epidemiology and control
Pigeon circovirus (picv) was detected in cloacal swab samples by means of a newly-developed, sensitive pcr, and samples from birds from two infected lofts indicated that picv could be detected in some birds for at least 27 weeks and for longer periods after infection than in blood.
Nucleotide sequence analysis of a novel circovirus of canaries and its relationship to other members of the genus Circovirus of the family Circoviridae.
Phylogenetic analysis of both the capsid and Rep protein-coding regions provided further evidence that CaCV is more closely related to CoCV and BFDV and more distantly related to GCV, PCV1 and PCV2.
Full‐Genome Sequence of Porcine Circovirus type 3 recovered from serum of sows with stillbirths in Brazil
Two full-genome sequences of porcine circovirus type 3 (PCV3) are reported. The genomes were recovered from pooled serum samples from sows who had just delivered litters with variable numbers of
Prevalence of Duck Circovirus Infection of Subclinical Pekin Ducks in South Korea
It is evident that DuCV can be associated with subclinical diseases and that subclinical infection could be economically important in ducks and in comparison of the relationship between bacterial diseases and morbidity in farms with and without DuCV.
Revisiting the taxonomy of the family Circoviridae: establishment of the genus Cyclovirus and removal of the genus Gyrovirus
Details are provided on an updated Circoviridae taxonomy ratified by the International Committee on the Taxonomy of Viruses in 2016, which establishes the genus Cyclovirus and reassigns the genus Gyrovirus to the family Anelloviraceae, a separate lineage of animal viruses that also contains circular ssDNA genomes.
New Reporter Gene-Based Replication Assay Reveals Exchangeability of Replication Factors of Porcine Circovirus Types 1 and 2
ABSTRACT Two types of porcine circovirus (PCV), which differ in their pathogenicity, are known. PCV type 2 (PCV2) is the etiological agent of postweaning multisystemic wasting syndrome in swine,
