Nucleotide sequence of porcine circovirus associated with postweaning multisystemic wasting syndrome in pigs.
This article describes the nucleotide sequence of a porcine circovirus (PCV) which possesses a high degree of association with postweaning multisystemic wasting syndrome (PMWS), a newly described disease of young pigs. The DNA sequence of this PMWS-associated PCV (pmws PCV) has 68% homology with that of a previously published nonpathogenic strain of PCV. The strains appear to be closely related...
متن کاملDetection of porcine circovirus types 1 and 2 in serum and tissue samples of pigs with and without postweaning multisystemic wasting syndrome.
Presence of porcine circovirus type 1 (PCV1) and PCV2 was studied in sera and superficial inguinal lymph nodes from postweaning multisystemic wasting syndrome (PMWS)-affected and non-PMWS-affected pigs by using in situ hybridization and PCR. PCV1 and PCV2 were found in less than 3% and more than 50% of the samples, respectively. The most sensitive technique and site was PCR in superficial ingui...
متن کاملDetection of a novel strain of porcine circovirus in pigs with postweaning multisystemic wasting syndrome.
Swine infectious agents, especially viruses, are potential public health risks associated with the use of pig organs for xenotransplantation in humans. Therefore, there is a need for better characterization of swine viruses and for the development of diagnostic tests for their detection. We report here isolation of a novel strain of porcine circovirus (PCV) from pigs with postweaning multisyste...
متن کاملHistopathological Diagnosis of Postweaning Multisystemic Wasting Syndrome
Postweaning multisystemic wasting syndrome (PMWS) is a disease of pigs first recognised in North America in 1991 and subsequently reported worldwide that is caused by Porcine circovirus 2 (PCV2), a member of the family Circoviridae. The most consistent feature of PMWS is a generalized depletion of lymphocytes. Secondary infections with opportunistic organisms are common. There is evidence that ...
متن کاملPorcine circovirus type 2 viremia and seroconversion in pigs from a farm affected by postweaning multisystemic wasting syndrome.
The aim of the study was to assess the usefulness of real-time PCR and serological methods as indicators of postweaning multisystemic wasting syndrome (PMWS) occurrence. Significantly higher level of porcine circovirus type 2 (PCV2) viral load in serum and significantly lower titre of specific antibodies in PMWS-affected pigs indicated that combination of quantitative PCR and serological method...
