Emergence of a Novel CRESS-DNA Virus Associated with Swine Reproductive Failure in China. [PDF]

Transbound Emerg Dis
The continuous emergence of circular Rep‐encoding single‐stranded (CRESS) DNA viruses across diverse hosts has been closely associated with the occurrence of severe diseases. Four circoviruses within the genus Circovirus have been identified in pigs, including porcine circovirus Type 1 (PCV1), PCV2, PCV3, PCV4, and PCV5.

Occurrence of diverse circoviruses in wild birds in Hungary [PDF]

Veterinary Research
Circoviruses (CVs) infect a wide range of avian hosts, including domestic, ornamental and wild birds. The immunosuppressive effect of these viruses could make the host more susceptible to other pathogens.

A SUMO interacting motif in the replication initiator protein of tomato yellow leaf curl virus is required for viral replication [PDF]

Journal of Virology
Circular Rep-encoding single-stranded (CRESS)-DNA viruses comprise a diverse group of viruses that use rolling-circle replication to copy their genomes. They infect organisms in almost all branches of the eukaryotic tree of life.

Identification and genomic characterization of a novel CRESS DNA virus from a calf with severe hemorrhagic enteritis in China. [PDF]

Virus Res, 2018
In this study, a novel circular replication-associated protein (Rep)-encoding single stranded (CRESS) DNA virus was discovered in diarrheic sample of a calf with severe hemorrhagic enteritis. The virus, named Bo-Circo-like virus CH, has a circular genome with 3909 nucleotides (nt). Six putative open reading frames (ORFs) were identified, including Rep,

Exploring the recombinant evolution and hosts of crucivirus based on novel oyster-associated viruses [PDF]

Frontiers in Microbiology
“Crucivirus” represents a group of viruses with chimeric genomes, significant for viral evolution and recombination studies. Their capsid proteins share homology with the RNA virus tombusvirus, while their replicase-associated proteins are homologous to ...

Strand-Specific Patterns of Codon Usage Bias Across Cressdnaviricota

Frontiers in Virology, 2022
The rapidly expanding phylum Cressdnaviricota contains circular, Rep-encoding single-stranded (CRESS) DNA viruses that are organized within seven established families, but many CRESS DNA virus sequences are not taxonomically defined. We hypothesized that

Diversity of CRESS DNA Viruses in Squamates Recapitulates Hosts Dietary and Environmental Sources of Exposure

Microbiology Spectrum, 2022
Replication-associated protein (Rep)-encoding single-stranded (CRESS) DNA viruses comprise viruses with covalently closed, circular, single-stranded DNA (ssDNA) genomes, and are considered the smallest known autonomously replicating, capsid-encoding ...

Virus discovery in all three major lineages of terrestrial arthropods highlights the diversity of single-stranded DNA viruses associated with invertebrates [PDF]

PeerJ, 2018
Viruses encoding a replication-associated protein (Rep) within a covalently closed, single-stranded (ss)DNA genome are among the smallest viruses known to infect eukaryotic organisms, including economically valuable agricultural crops and livestock ...
