Zoonotic transmission between pigs and humans has been confirmed. Human HEV infection is common in Nigeria; however, characterization of HEV infection in other species was lacking. The objective of this study was to investigate HEV infection in Nigerian pigs. A total of 286 serum samples from six states in Nigeria were tested for presence of anti-HEV IgG. Ninety fecal samples from one of these states (Plateau State) were tested for presence of HEV RNA. The overall prevalence of anti-HEV IgG-positive or suspect-positive pigs was 55.6% (159 of 286) with regional prevalence rates ranging from 36% (9 of 25; Delta State) to 88% (22 of 25; Taraba State). The overall HEV RNA prevalence rate was 76.7% (69 of 90). All polymerase chain reaction-positive samples belonged to HEV genotype 3 based on sequencing. The results indicate that HEV genotype 3 infection is widespread in Nigerian pigs.<\/jats:p>","DOI":"10.4269\/ajtmh.14-0144","type":"journal-article","created":{"date-parts":[[2014,7,8]],"date-time":"2014-07-08T05:00:12Z","timestamp":1404795612000},"page":"699-704","source":"Crossref","is-referenced-by-count":34,"title":["First Report of Hepatitis E Virus Circulation in Domestic Pigs in Nigeria"],"prefix":"10.4269","volume":"91","author":[{"given":"Olajide A.","family":"Owolodun","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Priscilla F.","family":"Gerber","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luis G.","family":"Gim\u00e9nez-Lirola","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacob K.
