Resumo: | There is no information about evidence of hepatitis E virus (HEV) infection in swines in Central Brazil. In order to assess if HEV circulates in swines of the State of Mato Grosso, Central Brazil, a seroprevalence study was conducted including pigs from 17 farms, corresponding to 13 counties. The animals were randomly chosen among pigs arriving to two slaughterhouses between December 2002 and February 2003. Serum samples were collected and tested for IgG antibodies against HEV (anti-HEV) by enzyme immunoassay (EIA). This EIA uses two HEV recombinant proteins as antigens, a mosaic protein (MP-II) and a protein containing region 452-617 of the ORF2 of the HEV Burma strain as coating antigens. 211 out of 260 pigs (81.2%; 95CI = 75.7%, 85.6%) were anti-HEV reactive. The seropositivity did not vary with gender or age, but ranges from 15% to 100% among the farms. Our results point out that HEV seems to circulate among pigs in Mato Grosso State, suggesting that this virus is spread over the region, as seen in other countries worldwide.
