Alessandra Marnie Martins Gomes de Castro, Adriana Cortez, Marcos Bryan Heinemann, Paulo Eduardo Brandão, and Leonardo José Richtzenhain
Porcine circovirus 2 (PCV-2) is associated with a broad range of syndromes. In this study, eight pig tissue samples from two Brazilian states were analyzed using six PCR primer pairs amplifying a 1705-bp fragment of the PCV-2 genome. The NJ distance-based...

Porcine circovirus type 2 (PCV2) viral components immunomodulate recall antigen responses
Tuija Kekarainen, Maria Montoya, Javier Dominguez, Enric Mateu, and Joaquim Segalés
Porcine circovirus type 2 (PCV2) is a single-stranded circular DNA virus infecting domestic pigs worldwide. Interaction of this virus with the immune system apparently modulates the immune response of the host. In the present study, the implication of...

Changes in peripheral blood leukocyte subpopulations in piglets co-infected experimentally with porcine reproductive and respiratory syndrome virus and porcine circovirus type 2
Kaichuang Shi, Huanrong Li, Xin Guoa, Xinna Ge, Hong Jia, Shijun Zheng and Hanchun Yang
Porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) are pathogens, which can significantly affect the swine industry worldwide. Field surveys suggest that simultaneous PRRSV and PCV2 infection is common in...

Genetic characterization of porcine circovirus type 2 in Republic of Korea.
Choi KS, Chae JS.
Porcine circovirus type 2 (PCV2) is a major causative agent of postweaning multisystemic wasting syndrome (PMWS). Sequence and phylogenetic analyses based on the ORF2 capsid protein gene fragment showed that field isolate in Republic of Korea (ROK), PCV2...

Examination for a viral co-factor in postweaning multisystemic wasting syndrome (PMWS)
Louise Lohse, Anette Bøtner, Anne-Sofie Ladekjær Hansen, Tina Frederiksen, Kitt Dupont, Charlotte S. Christensen, Poul Bækbo and Jens Nielsen
In order to test the hypothesis that a putative co-factor for the development of postweaning multisystemic wasting syndrome (PMWS) in pigs could be of viral origin, we performed extensive virological examinations on organ material from pigs diagnosed...

Rapid detection of porcine circovirus type 2 by loop-mediated isothermal amplification
Hao-tai Chen, Jie Zhang, De-hui Sun, Yue-feng Chu, Xue-peng Cai, Xiang-tao Liu, Xue-nong Luo, Qing Liu and Yong-sheng Liu
A method of loop-mediated isothermal amplification (LAMP) was employed to develop a rapid and simple detection system for porcine circovirus type 2 (PCV2). The amplification could be finished in 60 min under isothermal condition at 64 ºC by employing...

A review of viral diseases of the European wild boar: Effects of population dynamics and reservoir rôle
Francisco Ruiz-Fons, Joaquim Segalés and Christian Gortázar
There has been a worldwide increase in the number and geographical spread of wild boar populations in recent decades leading to an increase in both the circulation of disease agents and greater contact with domestic animals and humans. Diseases affect...

A piglet with concurrent polioencephalomyelitis due to porcine teschovirus and postweaning multisystemic wasting syndrome.
Takahashi M, Seimiya YM, Seki Y, Yamada M.
A piglet developed respiratory distress followed by difficulty in standing and unsteady gait. The lesions were characterized by polioencephalomyelitis with the predominant distribution in the brain stem, as well as lymphocyte depletion and histiocyte...

Evaluation of a nested polymerase chain reaction assay to differentiate between two genotypes of Porcine circovirus-2.
Lyoo KS, Kim HB, Joo HS.
Porcine circovirus-2 (PCV-2) is associated with several diseases in pigs, including postweaning multisystemic wasting syndrome (PMWS). A new genotype of PCV-2 was isolated from swine farms with and without clinical PMWS in North America. The new genotype...
