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

Transboundary and Emerging Diseases
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.

Pervasive Chimerism in the Replication-Associated Proteins of Uncultured Single-Stranded DNA Viruses [PDF]

Viruses, 2018
Numerous metagenomic studies have uncovered a remarkable diversity of circular replication-associated protein (Rep)-encoding single-stranded (CRESS) DNA viruses, the majority of which are uncultured and unclassified. Unlike capsid proteins, the Reps show

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 ...

Novel circular single-stranded DNA viruses identified in marine invertebrates reveal high sequence diversity and consistent predicted intrinsic disorder patterns within putative structural proteins [PDF]

Frontiers in Microbiology, 2015
Viral metagenomics has recently revealed the ubiquitous and diverse nature of single-stranded DNA (ssDNA) viruses that encode a conserved replication initiator protein (Rep) in the marine environment.

Dynamics and Conformations of a Full-Length CRESS-DNA Replicase

Viruses, 2023
Circular Rep-encoding single-stranded DNA (CRESS-DNA) viruses encode for a Replicase (Rep) that is essential for viral replication. Rep is a helicase with three domains: an endonuclease, an oligomeric, and an ATPase domain (ED, OD, and AD).

Unraveling the intra-species genomic diversity of sweetpotato-infecting CRESS-DNA and RNA viruses in Burkina Faso using Oxford Nanopore sequencing [PDF]

Frontiers in Microbiology
Sweetpotato is a key crop for global food security, particularly in Burkina Faso, where its productivity is increasingly threatened by viral diseases, especially those caused by CRESS-DNA viruses.

Identification and biochemical characterization of a novel porcine circovirus associated with porcine respiratory and diarrheal diseases [PDF]

Microbiology Spectrum
Eukaryotic circular Rep encoding single-stranded DNA (CRESS DNA) viruses exhibit high genomic diversity. Four species of circoviruses within the genus Circovirus have been identified in pigs, including the non-pathogenic porcine circovirus type 1 (PCV1),

Detection and Complete Genome Analysis of Porcine Circovirus 2 (PCV2) and an Unclassified CRESS DNA Virus from Diarrheic Pigs in the Dominican Republic: First Evidence for Predominance of PCV2d from the Caribbean Region

Viruses, 2022
We report here high rates (47.5%, 48/101) of detection of porcine circovirus 2 (PCV2) in diarrheic pigs from three pig farms in the Dominican Republic.
