| ABSTRACT Hepatitis E is caused by the hepatitis E virus (HEV) which is currently known to be a zoonotic pathogen transmitted by pigs. In Brazil, there is no information about the circulation of HEV in the swine herd of the Federal District. Therefore, a cross-sectional study was performed with sera from 449 domestic pigs, provided by the Secretary of Agriculture of the Federal District. Blood samples were collected between June and September 2014. A commercially available ELISA kit was used for the detection of IgG antibodies. High seroprevalence of antibodies to HEV was found, since 304 animals showed anti-HEV positive reactions (67.7%; 95% CI = 63.2%, 71.9%). The seropositivity presented no difference by gender or age. The results suggest that HEV... |

| The aim of the present study was to evaluate the prevalence of HEV, TTV and GBV-C/GBV-C/HGV in patients with acute viral hepatitis A, B and non-A-C. We evaluated sera of 94 patients from a sentinel program who had acute hepatitis A (N = 40), B (N = 42) and non-A-C (N = 12); 71 blood donors served as controls. IgM and anti-HEV IgG antibodies were detected by enzyme immunoassay using commercial kits. TTV and GBV-C/HGV were detected by nested PCR; genotyping was done by sequencing and phylogenetic analysis. Anti-HEV IgG was present in 38, 10 and 17% of patients with hepatitis A, B and non-A-C. Four patients with hepatitis A and 1 with non-A-C hepatitis also had anti-HEV IgM detected in serum. TTV was detected in 21% of patients with acute hepatitis and in 31%... |
