We report here the complete genome sequence of the porcine circovirus type 2 (PCV2) XZBK strain, isolated from central China. This is the first report of a member of the 1B subgroup of PCV2b central China. This finding will help in understanding the epidemiology and molecular characteristics of PCV2.

Porcine Circovirus Diseases (PCVD) and Porcine Circovirus Associated Disease (PCVAD) are synonymous names for a disease syndrome caused by porcine circovirus type 2 (PCV2) and originally described in the mid-1990’s as Postweaning Multisystemic Wasting Syndrome (PMWS). 2 While the acronyms PCVD and PMWS have been widely used over the last decade, the American Association of Swine Veterinarians i...

Porcine circovirus type 1 (PCV1) is a nonpathogenic circovirus, and a contaminant of the porcine kidney (PK-15) cell line. We present the complete and annotated genome sequence of strain Szeged of PCV1, determined by Pacific Biosciences RSII long-read sequencing platform.

A long-established epidemic of enteritis, caused by an unidentified pathogen distinct from parvovirus, has now been recognized in mink. In 2013, we identified a novel circovirus by degenerate PCR and fully sequenced its genome. This virus differs substantially from currently known members of the genus Circovirus and represents a new species.

The complete nucleotide sequence (1759 nt) of the ssDNA genome of porcine circovirus (PCV) was determined from a cloned dsDNA replicative form isolated from PCV-infected cells. Sequence analysis detected no significant nucleic acid or protein similarity with another animal circovirus, chicken anaemia virus (CAV) but, surprisingly, the highest protein similarity was obtained between the product ...

Interest in porcine circovirus has been stimulated by the recent emergence of postweaning multisystemic wasting syndrome (PMWS) in pigs and the potential use of pig organs for xenotransplantation in humans. Porcine circovirus type 1 (PCV1) is considered to be widespread in pigs but nonpathogenic. Circovirus type 2 (PCV2) is a similar virus but has been differentiated only recently as a separate...

This report describes the identification and characterization of a novel circovirus using metagenomic approaches in respiratory fluid samples from Brazilian free-tailed bats (Tadarida brasiliensis). The genome and deduced protein sequences share low identity with another circovirus recovered in distantly related bats from China.

A fox circovirus was identified in serum samples from foxes with unexplained neurologic signs by using viral metagenomics. Fox circovirus nucleic acid was localized in histological lesions of the cerebrum by in situ hybridization. Viruses from the family Circoviridae may have neurologic tropism more commonly than previously anticipated.

Porcine circovirus type 2 (PCV-2) is the etiologic agent of porcine circovirus-associated disease (PCVAD). PCV-2 is classified into three genotypes. Here, we present the complete genomic sequences of two PCV-2 isolates (KM and H026) with an unusual sequence duplication in the rep gene coding for viral replicase proteins.

The porcine circovirus type 2 (PCV2) antibody and DNA status of porcine plasma products collected during the commercial spray-drying process were evaluated. Samples evaluated included 52 pooled liquid plasma (fresh) samples collected at 14 regional abattoirs before transport to 1 of 2 spray-drying facilities, 32 pooled liquid plasma (concentrated) samples collected after arrival at the spray-dr...
