AB  - BACKGROUND: In Vietnam, lack of animal health information is considered a major 
      challenge for pig production. The main objective of this study was to assess the 
      seroprevalences of five pathogens [porcine circovirus type 2 (PCV2), porcine 
      reproductive and respiratory syndrome virus (PRRSV), mycoplasma hyopneumoniae (M. 
      hyo), Japanese encephalitis virus (JEV) and leptospirosis] and to better 
      characterize the farm movements through a survey. RESULTS: A total of 600 samples 
      were collected from 120 farms from Bac Giang and Nghe An. Among unvaccinated 
      herds, the highest seroprevalence was found for JE with 73.81% (95% CI: 
      68.39-78.74) in Bac Giang and 53.51% (95% CI 47.68-59.27) in Nghe An. 
      Seroprevalences for PCV2 and M.hyo were 49.43% (95% CI: 45.06-53.80) and 46.06% 
      (95% CI: 41.48-50.69) among unvaccinated animals. Accumulative co-infections for 
      JE (86.25%) showed the highest level followed by M. hyo (66.25%) and PCV2 
      (62.50%). Three co-infections with JE had the highest positive rate (28.75%) 
      followed by four co-infections (25.0%). Medium farms had relatively higher herd 
      prevalences for all pathogens, except from leptospirosis. Overall, farmers 
      exported/imported their pigs at the most 1-2 times every 6 months. Some 
      respondents (5% for exportation and 20% for importation) had moved pigs more than 
      6 times over the last 6 months. CONCLUSIONS: Our study provided another pool of 
      evidence that showed that PCV2, PRRS and H. hyo are endemic in pigs in Vietnam. 
      Given the economic impacts of these pathogens elsewhere, the findings confirm the 
      need for studies to evaluate the association between antibody response and 
      clinical relevance as well as to assess the economic impact of co-infections at 
      farm level. We also found that high seroprevalences of JE and leptospirosis were 
      detected in pigs. From a pubic health point of view, it is crucial to raise 
      public awareness especially for high risk occupations (mainly pig farm workers).
