Genetic Characterization of Porcine Circovirus Type 2 from Pigs with Porcine Circovirus Associated Diseases in Argentina
Porcine circovirus type 2 (PCV-2) has been associated with syndromes grouped by the term porcine circovirus associated diseases (PCVAD). The PCV-2 isolates have been grouped into two major groups or genotypes according to their nucleotide sequence of whole genomes and/or ORF-2: PCV-2b, which have, in turn, been subdivided into three clusters (1A-1C), and PCV-2a, which has been subdivided into f...
متن کاملIdentification of pig circovirus type 2 in New Zealand pigs.
Interest in porcine circovirus has been stimulated by the recent emergence of postweaning multisystemic wasting syndrome (PMWS) in pigs and the potential use of pig organs for xenotransplantation in humans. Porcine circovirus type 1 (PCV1) is considered to be widespread in pigs but nonpathogenic. Circovirus type 2 (PCV2) is a similar virus but has been differentiated only recently as a separate...
متن کاملLeukogram abnormalities in gnotobiotic pigs infected with porcine circovirus type 2.
Porcine circovirus type 2 (PCV2) is a single-stranded circular DNA virus that is the causative agent of porcine circovirus associated disease (PCVAD), a disease complex affecting swine around the world. Although this virus is believed to negatively affect the host's immune system, the mechanism by which PCV2 induces disease is not completely understood. This report describes a series of PCV2 ex...
متن کاملInteraction of porcine circovirus type 2 and Mycoplasma hyopneumoniae vaccines on dually infected pigs.
The objective of this study was to determine the effects of porcine circovirus type 2 (PCV2) and Mycoplasma hyopneumoniae vaccinations on disease severity in an experimental PCV2-M. hyopneumoniae dual challenge model. Vaccine effectiveness was evaluated using microbiological (PCV2 viremia and M. hyopneumoniae nasal shedding), immunological (neutralizing antibodies and interferon-γ-secreting cel...
متن کاملApoptosis in lymphoid organs of pigs naturally infected by porcine circovirus type 2.
The objective of the present study was to evaluate the involvement of apoptosis in the development of post-weaning multisystemic wasting syndrome (PMWS) lymphoid-depletion lesions. Twenty-one pigs that were categorized into three different lesional severity stages (S1, n=5; S2, n=7; S3, n=9) and five healthy control pigs (stage S0) were used. From all pigs, samples of thymus, spleen, tonsil, il...
