Isolation of circovirus from lesions of pigs with postweaning multisystemic wasting syndrome.
Postweaning multisystemic wasting syndrome (PMWS), an apparently new disease, has been recognized in swine herds in western Canada. Young pigs with this disease have progressive weight loss,Expand
Characterization of novel circovirus DNAs associated with wasting syndromes in pigs.
Porcine circovirus (PCV) was initially recognized as a contaminant of continuous pig kidney cell lines and was not thought to be pathogenic. Antibodies reactive to the cell culture isolate of PCVExpand

Circoviruses are small, non-enveloped, icosahedral viruses that are unique among animal viruses in having circular, single-stranded DNA genomes. Their genomes are also the smallest possessed byExpand
Novel porcine circoviruses from pigs with wasting disease syndromes.
Comparison of Two Aquatic Alphaviruses, Salmon Pancreas Disease Virus and Sleeping Disease Virus, by Using Genome Sequence Analysis, Monoclonal Reactivity, and Cross-Infection
ABSTRACT Cell culture isolates of salmon pancreas disease virus (SPDV) of farmed Atlantic salmon and sleeping disease virus (SDV) of rainbow trout were compared. Excluding the poly(A) tracts, theExpand
Sequence of porcine circovirus DNA: affinities with plant circoviruses.
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 analysisExpand
A single chicken anemia virus protein induces apoptosis.
Chicken anemia virus (CAV) causes cytopathogenic effects in chicken thymocytes and cultured transformed mononuclear cells via apoptosis. Early after infection of chicken mononuclear cells, theExpand
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) sequenceExpand

The diseases associated with psittacine beak and feather disease virus (BFDV), pigeon circovirus (PiCV) and goose circovirus (GoCV), which can be classified with porcine circovirus type 2 (PCV2) asExpand
Identification of chicken enterovirus-like viruses, duck hepatitis virus type 2 and duck hepatitis virus type 3 as astroviruses
Earlier work identified and biologically characterized antigenically distinct enterovirus-like viruses (ELVs) of chickens. Three of these ELVs can now be identified as astroviruses. CharacterizationExpand
