Enhanced immune response to inactivated porcine circovirus type 2 (PCV2) vaccine by conjugation of chitosan oligosaccharides

Carbohydrate Polymers, 2017
This study aimed to investigate the effect of chitosan oligosaccharide (COS) conjugation on the immunogenicity of porcine circovirus type-2 (PCV2) vaccine. Two conjugates (PCV2-COS-1 and PCV2-COS-2) were designed by covalent conjugation of an inactivated

Detection of porcine Circovirus type 2 (PCV2) variants PCV2-1 and PCV2-2 in Brazilian pig population

Research in Veterinary Science, 2009
In the present study whole genome of six Brazilian isolates of PCV2 were sequenced, analyzed and compared with 35 other sequences (24 from other countries and 17 from Brazil). The phylogenetic analysis showed that mostly Brazilian variants of PCV2 were grouped as PCV2-1.

Porcine circovirus type 2 (PCV2) vaccination reduces PCV2 in a PCV2 and Salmonella enterica serovar Choleraesuis coinfection model

Veterinary Microbiology, 2013
We previously reported that prior porcine circovirus type 2 (PCV2) infection potentiates the severity of clinical signs, lung lesions, and fecal shedding and tissue dissemination of Salmonella enterica serovar Choleraesuis in infected pigs. Here, we evaluated whether PCV2 vaccination is effective in reducing fecal shedding and tissue dissemination of S.

Porcine circovirus type 2 (PCV2) vaccination is effective in reducing disease and PCV2 shedding in semen of boars concurrently infected with PCV2 and Mycoplasma hyopneumoniae

Theriogenology, 2011
The objectives were to determine whether the amount of porcine circovirus type 2 (PCV2) shed in semen increased in boars experimentally coinfected with Mycoplasma hyopneumoniae (MHYO), and whether PCV2 vaccination of boars prior to PCV2 exposure reduced PCV2 viremia and virus shedding in semen.

PCV3 in Thailand: Molecular epidemiology and relationship with PCV2

Transboundary and Emerging Diseases, 2021
Porcine circovirus type 3 has been circulating throughout the world and since their first report, various clinical signs and disease developments have been documented. The virus is similar to the closely related PCV2 and is associated with several clinical signs called porcine circovirus-associated diseases (PCVAD).

Origin of porcine circovirus type 2 (PCV2) from swine affected by PCV2‐associated diseases in Croatia

Veterinary Record, 2014
Porcine circovirus type 2 (PCV2) causes some of the most significant economic losses in pig production. Several multisystemic syndromes have been attributed to PCV2 infection, which are known as PCV2‐associated diseases (PCVDs). This study investigated the origin and evolution of PCV2 sequences in domestic pigs and wild boars affected by PCVDs in ...

Susceptibility of calves to porcine circovirus-2 (PCV2)

Veterinary Microbiology, 2014
Circoviruses are known to infect pigs and birds and cause severe diseases with various clinical signs. Porcine circovirus-2 (PCV2), associated with severe economic losses, was detected in rodents, mosquitoes, cattle, and in calves affected with bovine neonatal pancytopenia (BNP).

The levels of PCV2 specific antibodies and viremia in pigs

Research in Veterinary Science, 2007
Porcine circovirus 2 quantification by real-time PCR and determination of virus specific antibodies using a peptide based ELISA test was performed on a total of 400 serum samples. Samples for antibody measurement and virus quantification were obtained from a conventional pig farm with a clinical form of post-weaning multisystemic wasting syndrome ...

Prolonged detection of PCV2 and anti-PCV2 antibody in oral fluids following experimental inoculation.

Transboundary and emerging diseases, 2016
The onset, level and duration of PCV2 and anti-PCV2 antibody in oral fluid were evaluated using samples collected from experimentally inoculated pigs for 98 days post-inoculation (DPI). Pigs (n = 24) were obtained at 3 weeks of age and randomly allocated to 4 treatment pens of 6 pigs each: (i) negative control group; (ii) inoculated with PCV2a (strain ...
