hepadnaviridae การใช้
- Examples of the second type are the " Hepadnaviridae ", which includes Hepatitis B virus.
- This unique replication strategy, plus they have extremely small viral genome, and a very narrow host range and tissue tropism, make it designated as family hepadnaviridae.
- The virus particles of some virus families, such as those belonging to the " Hepadnaviridae ", contain a genome that is partially double-stranded and partially single-stranded.
- Pathogenic viruses are diseases mainly those of the families of : Adenoviridae, Picornaviridae, Herpesviridae, Hepadnaviridae, Flaviviridae, Retroviridae, Orthomyxoviridae, Paramyxoviridae, Papovaviridae, Polyomavirus, Rhabdoviridae, Togaviridae.
- However, non-retroviruses also use RT ( for example, the hepatitis B virus, a member of the Hepadnaviridae, which are dsDNA-RT viruses, while retroviruses are ssRNA viruses ).
- CccDNA was first described in bacteriophages, but it was also found in some cell cultures where an infection of DNA viruses ( " Polyomaviridae " ) was detected . cccDNA is typical of " Caulimoviridae " and " Hepadnaviridae ", including the hepatitis B virus ( HBV ) . cccDNA in HBV is formed by conversion of capsid-associated relaxed circular DNA ( rcDNA ).
