Identification of porcine circovirus-3 in Mozambique
Veterinary Research Communications, 2021Porcine circovirus 3 (PCV-3) has been associated with an assortment of clinical conditions in pigs and has been reported in many countries worldwide. In Africa there is no data on the presence of PCV-3. In this study, DNA samples collected from 91 pigs between 2011 and 2019 in nine of the ten provinces of Mozambique in the context of African swine ...

Porcine circoviruses (PCVs) belong to the genus Circovirus and the family Circoviridae, and they are the smallest known viruses that replicate autonomously in mammalian cells. They are nonenveloped, and they have characteristic single-stranded, negative-sense, circular DNA. Two types of divergent PCVs are recognized: PCV1 and PCV2. About 20 years ago,

Porcine circovirus type 3 in the UK
Veterinary Record, 2017Circoviruses are circular, single-stranded DNA viruses and the smallest known autonomously replicating viruses.1 Two species of circovirus are known to infect pigs: porcine circovirus type 1 (PCV1) – which has not been associated with clinical disease – and porcine circovirus type 2 (PCV2), which was first isolated and characterised in the late 1990s ...

Association of porcine circovirus 2 with porcine respiratory disease complex
The Veterinary Journal, 2003A retrospective study was performed on natural cases of porcine respiratory disease complex (PRDC) to determine the association and prevalence of PRDC with porcine circovirus 2 (PCV2) and other co-existing pathogens in Korea. Histologically, alveolar septa were markedly thickened by infiltrates of mononuclear cells.

Kinetics of porcine circovirus type 2 replication
Archives of Virology, 2002The kinetics of porcine circovirus type 2 (PCV2) replication in PK15 cells was examined. During productive infection, viral antigens, RNA transcripts and progeny viruses all increased in a time dependent manner. Viral antigens were observed in a few cells at 18 hour postinfection (h p.i.) and cell-free progeny viruses began to appear at about 30 h p.i.

Effect of porcine circovirus infection on porcine alveolar macrophage function
Veterinary Immunology and Immunopathology, 1996The effect of porcine circovirus (PCV) infection of porcine alveolar macrophage cultures on some of the functional properties of these cells are reported. PCV infection of alveolar macrophages did not effect their ability to phagocytose and kill complement-coated yeast cells or the expression of Fc or complement receptors. A transient increase in major

Infection studies on human cell lines with porcine circovirus type 1 and porcine circovirus type 2
Xenotransplantation, 2004Abstract: Background: The lack of human donor organs in allotransplantation has led to a proposal for the use of porcine tissues and organs as alternative therapeutic material for humans. Besides immunological problems like graft rejection, one of the major concerns is the transmission of porcine microorganisms as viruses, bacteria and fungi to a ...

Transboundary and Emerging Diseases, 2019
PCV2 is globally spread pathogen involved in a number of diseases (PCVD). Commonly used vaccines against PCV2 are proved to be highly efficacious. The role of recently discovered PCV3 for pig health and interference with PCV2 remains unknown. The study performed on serum samples from seven farms vaccinated against PCV2 and four non-vaccinated showed ...

Studies on epidemiology and pathogenicity of porcine circovirus
Archives of Virology, 1986Antibodies to porcine circovirus (PCV) which is the smallest animal virus known so far were found in 77-95 per cent of sera from slaughter pigs gathered in Berlin and two districts of Northern Germany. About 60 per cent of these positive sera had relatively high titres similar to those in experimentally infected pigs 3-6 weeks after infection.

Viral DNA from Cells Infected with Porcine Circovirus
Zentralblatt für Bakteriologie, Mikrobiologie und Hygiene. Series A: Medical Microbiology, Infectious Diseases, Virology, Parasitology, 1988It has been demonstrated earlier that the genome of the porcine circovirus (PCV) isolated from virions is a circular single-stranded DNA (ssDNA). This report describes the isolation and characterization of PCV-specific DNA from infected cell cultures.
