Identification of a new group of bovine viral diarrhea virus strains associated with severe outbreaks and high mortalities.
Characterization of the last two-thirds of the 5' untranslated region (5'UTR) of their genome and virus neutralization experiments with polyvalent antisera raised in different animals both demonstrated that these strains formed a distinct group. Expand
The family Parvoviridae
The proposals introduce new species and genera into both subfamilies, resolve one misclassified species, and improve taxonomic clarity by employing a series of systematic changes. Expand
A viral phospholipase A2 is required for parvovirus infectivity.
Sequence analysis revealed phospholipase A2 (PLA2) motifs in capsid proteins of parvoviruses. Although PLA2 activity is not known to exist in viruses, putative PLA2s from divergent parvoviruses,Expand
Practice and theory of enzyme immunoassays
1. Introduction. 2. Outline of the strategies for immunoassays. 3. Non-immunological molecular recognition systems used in immunoassays. 4. The nature of immunogens, antigens and haptens. 5.Expand
The emergence of porcine circovirus 2b genotype (PCV-2b) in swine in Canada.
The appearance of the PCV-2b genotype in Canada may explain the death rate increase related to postweaning multisystemic wasting syndrome, but this relationship has to be confirmed. Expand
The structure of porcine parvovirus: comparison with related viruses.
The structure of baculovirus-expressed porcine parvovirus (PPV) capsids was solved using X-ray crystallography and was found to be similar to the related canine parvovirus (CPV) and minute virus ofExpand
The VP1 capsid protein of adeno-associated virus type 2 is carrying a phospholipase A2 domain required for virus infectivity.
Results suggest that pvPLA2 activity is required for a step following perinuclear accumulation of virions but prior to early gene expression, as measured by Rep immunofluorescence. Expand
Genome organization of the Kresse strain of porcine parvovirus: identification of the allotropic determinant and comparison with those of NADL-2 and field isolates
In vitro cell systems which differentiated the virulent from the vaccinal strains were established and chimeric infectious clones of the Kresse and NADL-2 strains were used to identify the allotropic determinant located in the VP1/VP2 region. Expand
Construction and sequencing of an infectious clone of the human parvovirus B19.
Human parvovirus B19 has a nonenveloped, icosahedral capsid packaging a linear single-stranded DNA genome of 5.6 kb with long inverted terminal repeats (ITR) at both the 5' and 3' end. PreviousExpand
Densonucleosis viruses constitute an increasingly diversified subfamily among the parvoviruses
A taxonomic structure for the Densovirinae subfamily including four genera instead of the three adopted recently by the ICTV is proposed, and one putative genus, Bidensovirus, is proposed for densoviruses with a bipartite genome which replicate differently from other parvoviruses. Expand
