Avihepadnavirus

Avihepadnavirus, is the second genus of the Hepadnaviridae family, the first genus being the Orthohepadnaviruses. The evihepadnavirus or equivalently, the avian hepadnavirus, consist of viruses which exclusively infect birds. This distinguishes from the orthohepadnaviruses, which only affect mammals. Even though the overall genome structure is similar in the two genuses, the similarities in the sequences are minimal.^[1] The type species of this genus is the duck hepatitis B virus (DHBV). Other species within the genus include heron hepatitis B virus (HHBV), snow goose hepatitis B virus (SGHBV), Ross Goose hepatitis B virus (RGHBV), stork hepatitis B virus (SHBV) and crane hepatitis B virus(CHBV). Infection with the virus is restricted to the species from which the virus has been isolated, or to closely related species.^[1]
