Lack of Genetic Diversity in Newly Sequenced Porcine Circovirus Type 1 Strains Isolated 20 Years Apart [PDF]

The complete genome sequences of a porcine circovirus type 1 (PCV1) strain isolated in 1990 and one isolated in 2011 were obtained and compared to the sequences of other available PCV1 isolates.

Development and validation of an ELISA using a protein encoded by ORF2 antigenic domain of porcine circovirus type 2 [PDF]

, 2010
Background The capsid protein (ORF2) is a major structural protein of porcine circovirus type 2 (PCV2). A simple and reliable diagnostic method based on ORF2 protein immunoreactivity would serve as a valuable diagnostic method for detecting serum ...

A novel kirkovirus may be associated with equine gastrointestinal disease

Equine Veterinary Journal, Volume 58, Issue 2, Page 414-422, March 2026.
Abstract Background Many cases of equine enterocolitis are suspected to be infectious in nature, but no pathogen is identified in many cases. Objectives Perform next‐generation sequencing on faeces collected from cases of equine enterocolitis for the presence of novel viruses and determine if an identified novel virus is associated with cases of equine

Porcine circovirus: Transcription and DNA replication

Virus Research, 2012
This review summarizes the molecular studies pertaining to porcine circovirus (PCV) transcription and DNA replication. The genome of PCV is circular, single-stranded DNA and contains 1759-1768 nucleotides. Both the genome-strand (packaged in the virus particle) and the complementary-strand (synthesized in the new host) encode viral proteins.

Pathogenesis and Transmission of a Reassorted H1 Influenza A Virus Detected in North American Swine

Influenza and Other Respiratory Viruses, Volume 20, Issue 2, February 2026.
ABSTRACT Background The USDA influenza A virus in swine national surveillance plan identified an increase in the detection frequency of a group of swine 1A.1.1.3 hemagglutinin (HA) clade viruses. This change was associated with reassortment events that resulted in new neuraminidase (NA) gene pairings.

First Molecular Detection of Torque Teno Canis Virus in Apparently Healthy Dogs in Southern Italy

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
•Torque teno canis virus has been detected in dogs from southern Italy. •Detection of TTCaV DNA was more frequent in dogs with an altered faecal score, mixed‐breed and belonging to kennels. ABSTRACT Background Torque teno viruses are viruses with unclear pathogenic potential, as conflicting evidence has classified this family of viruses as harmless and
