Abstract
This study reports the prevalence of duck hepatitis A virus (DHAV) types 1 and 3 on Korean duck farms. By RT-nested PCR assays specific for DHAV-1 or DHAV-3, DHAV-1 was detected in 9 of 157 liver samples (5.7 %) from 2 of 30 farms (6.7 %), and DHAV-3 was positive in 104 of 157 liver samples (66.2 %) from 23 of 30 farms (76.7 %). Dual infections with DHAV-1 and DHAV-3 were detected in 23 of 157 samples (14.6 %) from 5 of 30 farms (16.7 %). The data indicate that DHAV-3 infections are prevalent and that DHAV-1 reemerged in Korea, resulting in dual infections on several farms. Our data will help to establish a vaccination policy against DHAV-1 and DHAV-3 in Korea.
