Title: | Identification of recently described porcine parvoviruses in archived North American samples from 1996 and association with porcine circovirus associated disease | Contributor(s): | Opriessnig, Tanja (author); Xiao, Chao-Ting (author); Gerber, Priscilla Freitas (author) ; Halbur, Patrick G (author) | Publication Date: | 2014 | DOI: | 10.1016/j.vetmic.2014.06.024 | Handle Link: | https://hdl.handle.net/1959.11/21268 | Abstract: | The association of porcine circovirus (PCV) type 2 and porcine parvovirus (PPV) type 1 as a cause of porcine circovirus associated disease (PCVAD) is well established. The objective of this study was to investigate the prevalence rates of classical PPV1 and recently recognized PPV2-5 in serum and lung samples from pigs and farms with known PCV2 status. A total of 586 serum samples and 164 lung homogenates collected from 1996 to 2013 in the USA and Canada were utilized. All samples were tested for PPV1-5 and PCV2. PCV2 was detected in 27.7% (162/586) and PPV in 48.8% (286/586) of the serum samples, whereas 78.7% (129/164) of the lung tissues were positive for PCV2 and 56.7% (93/164) were positive for PPV. Overall, PPV2 had the highest prevalence rates in sera (35.2%) and tissues (42.7%). Concurrent infection of PCV2 and PPV occurred in 14.3% (84/586) of the serum samples and in 49.4% (81/164) of the tissue samples. Moreover, the prevalence of PPV1 or PPV2 DNA was significantly higher in tissues containing high amounts of PCV2 DNA compared to non-PCVAD cases. The frequency of concurrent PPV/PCV2 infection was higher for PCVAD herds compared to negative or subclinically infected herds. PPV2, PPV3 and PPV4 were all identified in samples collected in 1998 and PPV5 was first identified in 2006. The obtained findings indicate that similar to PCV2, PPVs are widespread in North American pigs. Nevertheless, diagnostic investigations into PCVAD cases should give more consideration to the role of PPV1 and PPV2 as contributing cofactors. | Publication Type: | Journal Article | Source of Publication: | Veterinary Microbiology, 173(1-2), p. 9-16 | Publisher: | Elsevier BV | Place of Publication: | Netherlands | ISSN: | 1873-2542 0378-1135 |
