Haemorrhagic nephritis and enteritis of geese (HNEG) is a fatal disease caused by goose haemorrhagic polyomavirus (GHPV). The aim of our study was to investigate a field outbreak of HNEG by pathological methods and real-time PCR assay using light upon extension (LUX PCR) with special regard to the possibility of vertical transmission. This is the first time that presence of GHPV was confirmed in goslings that died within 4 days after hatching showing typical symptoms of HNEG, which indicates vertical transmissibility as the shortest incubation period of HNEG is 6 days. The way of viral transmission is a key issue and thus the disease control measurements and HNEG epizootiology may be revised based on the findings of this study.
