The complete genome of a novel Circovirus isolated from an Australian raven (Corvus coronoides) with feather lesions similar to those that occur in psittacine beak and feather disease is reported. Degenerate polymerase chain reaction primers were designed to amplify and sequence novel Circovirus DNA from affected feathers. Sequence analysis indicated that the tentatively named raven circovirus (RaCV) was 1898 nucleotides in size with two major open reading frames synonymous with other avian… 
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).
Molecular characterization of a recently identified circovirus in zebra finches (Taeniopygia guttata) associated with immunosuppression and opportunistic infections
Analyses including partial sequences of the replication-associated protein gene of the zebra finch circovirus strains from all 14 birds supported the existence of two main clusters, and high genetic diversity was detected in the circoviruses from individualZebra finches.
Detection and Molecular Characterization of a Novel Species of Circovirus in a Tawny Owl (Strix aluco) in Southern Italy
Little can be said on its biology and pathogenicity, and further efforts are needed to better characterize its epidemiology.
A new duck circovirus sequence, detected in velvet scoter (Melanitta fusca) supports great diversity among this species of virus
The viral sequence obtained from the velvet scoter suggests that DuCV may infect birds from the Anatinae sub-family, and support previous reports that duck circovirus (DuCV) is a species with a high degree of diversity.
Characterization of a novel circo-like virus in Aedes vexans mosquitoes from Germany: evidence for a new genus within the family Circoviridae.
A novel circo-like virus is characterized in Aedes vexans mosquitoes from Germany whose main putative ORFs shared very low amino acid identity with those of previously characterized circoviruses and cyclovirus PCRs.
Sequence comparison of pigeon circoviruses.
Ubiquiter circovirus sequences raise challenges in laboratory diagnosis: the case of honey bee and bee mite, reptiles, and free living amoebae.
The results indicate that attention is needed when broad-spectrum rep gene specific polymerase chain reaction is chosen for laboratory diagnosis of circovirus infections, and raises the possibility that detection of novel or unusual rep-like elements in some host species might originate from the microbial community of the host.
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.


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.
Genome sequence determinations and analyses of novel circoviruses from goose and pigeon.
The genomes of novel circoviruses from goose and pigeon, which were isolated using degenerate primer and inverse primer PCR methods, were cloned and sequenced. Comparative nucleotide (nt) sequence
Cloning and sequencing of columbid circovirus (CoCV), a new circovirus from pigeons
Phylogenetic analyses suggest classification of CoCV as member of the genus Circovirus of the virus family Circoviridae as member with 55% homology to the genome of psittacine beak and feather disease virus and more distantly related to porcine circovirus type 2.
Psittacine beak and feather disease virus nucleotide sequence analysis and its relationship to porcine circovirus, plant circoviruses, and chicken anaemia virus.
These findings provide further evidence of a close relationship among BFDV, PCV, and plant circoviruses but not chicken anaemia virus.
Beak and feather disease virus and porcine circovirus genomes: intermediates between the geminiviruses and plant circoviruses
SummaryCircoviruses are a diverse group of animal and plant pathogens with undefined relationships to one another but for their non-geminate, non-enveloped capsids and circular, single-stranded DNA
Sequence of porcine circovirus DNA: affinities with plant circoviruses.
Findings show that PCV is unique in that it bridges the gap between animal and plant circovirus, and that rolling-circle replication may operate during PCV DNA replication.
Characterization of novel circovirus DNAs associated with wasting syndromes in pigs.
Cl cloning and characterization of novel circovirus DNAs purified from virus isolates made from tissues of North American and European pigs with wasting syndromes are reported, providing evidence for a new type of possibly pathogenic PCV.

Cloning and sequencing of Duck circovirus (DuCV)
Phylogenetic analysis shows close relation of Du CV with Goose circovirus and suggests classification of DuCV as a new member of the genus Circovirus of the virus family Circoviridae.
