Abstract
Swine hepatitis E virus (HEV) appears to be common among pigs around the world.HEV is also considered a zoonotic disease and pigs are more likely the primary reservoir. Hepatitiscaused by HEV infection has been a public health problem in developing countries. However, recentseroprevalence studies indicate that the HEV have been reported in several industrialized countries ourresearches aimed to investigate the prevalence of HEV antibodies in pigs from different breadingconditions in the eastern region of Romania. A total of 340 serum samples collected during 2008-2011, from clinically healthy pigs were tested using two commercial indirect ELISA. The overallprevalence of anti-HEV antibodies was 15.58%, the percentage of seropositive pigs varied greatlyfrom herd to herd (0 - 44.4%). In addition, from the same region, serum samples of 112 humans werescreened for the presence of anti-HEV IgG antibodies by ELISA (produced by MP Biomedicals). Thesera from 8 humans (7.14%) were anti-HEV IgG reactive. This is the first study showing that HEV isprevalent in the Romanian pig herds. These results indicate that subclinical HEV infections mayprevail in swine and human populations from the same region.
