The article presents data on the persistence of type 2 circovirus in one farms Republic Belarus. presence pathogen genome pigs different ages was established, and comparative results PCR ELISA were presented.

Background: Circoviruses are small, non-enveloped, single stranded DNA viruses. There is scarce information about these agents in non-psittacine birds. Aims: It is attempted to detect and characterize circoviruses in non-psittacine birds. Methods: Forty-five samples were collected from different non-psittacine species belonging to seven avian o...

Pigeon circovirus infection is an immunosuppressive disease of pigeons carried on by the widely recognized virus known as (PiCV). Additionally, due to PiCV’s activity, a group diseases collectively “young pigeon syndrome” (YPDS) occurs. This study aims provide information about transportation throughout world, symptoms that have been identified has progressed, and diagnostic methods recently de...

Circoviruses are present worldwide in birds and pigs but their occurrence in fish has not yet been reported. Recently, increased mortality was observed in barbel fry (Barbus barbus) in Hungary. This paper reports the detection of previously unknown circular viral DNA genomes in barbels by the use of a circovirus-specific wide-range nested PCR. The analysis of two complete genomes (Barbel circov...

Porcine circovirus type 2 (PCV2) is a small, non-enveloped, single-stranded DNA virus in the genus Circovirus within the family Circoviridae.1 It has been incriminated as a major causative agent of postweaning multisystemic wasting syndrome (PMWS), which is known as PCV2-associated diseases (PCVAD);2,3 PCVAD is considered to be an economically important global issue. Most Korean swine farms (95...

We report here for the first time the genome sequence of a rearranged porcine circovirus type 2 (PCV2) strain, CH-IVT1, isolated from PCV2-infected PK-15 cells. The complete circular genome of the CH-IVT1 is 605 nucleotides (nt) in length. The finding will help us to understand the molecular evolution of PCV2 and the relationship between PCV2 and PCV-associated diseases.

Six successive transmission trials were carried out from 4 to 39 days post inoculation (DPI) to determine the features of the infectious period for PCV2-infected pigs. The infectiousness of inoculated pigs, assessed from the frequency of occurrence of infected pigs in susceptible groups in each contact trial, increased from 4 to 18 DPI (0, 7 and 8 infected pigs at 4, 11 and 18 DPI, respectively...

We characterized the complete genome of a novel dog circovirus (DogCV) from the liver of a dog with severe hemorrhagic gastroenteritis, vasculitis, and granulomatous lymphadenitis. DogCV was detected by PCR in fecal samples from 19/168 (11.3%) dogs with diarrhea and 14/204 (6.9%) healthy dogs and in blood from 19/409 (3.3%) of dogs with thrombocytopenia and neutropenia, fever of unknown origin,...

Since the characterization of psittacine beak and feather disease (PBFD) in 1984, a wide range of avian circoviruses have been discovered with varying pathogenic effects amongst a diverse range of avian hosts. Until recently these circovirus species were thought to be restricted to within avian Orders such as the Psittaciformes for beak and feather disease virus (BFDV) and Columbiformes for pig...

Porcine circovirus type 2 (PCV2) is the primary causative agent of porcine circovirus associated disease (PCVAD), an economically important swine disease that causes wasting in pigs 5-18 weeks of age. There exist two different types of porcine circoviruses: porcine circovirus type 1 (PCV1) was discovered as a contaminant of porcine kidney (PK-15) cells and was determined to be nonpathogenic in ...
