Baltimore classification



طبقه بندی ویروس ها بر اساس سیستم بالتیمور

The Baltimore Classification of viruses is based on the method of viral mRNA synthesis

 در حال حاضر دو طرح عمده مورد استفاده برای طبقه بندی از ویروس ها وجود دارد : سیستم ICTV و سیستم طبقه بندی بالتیمور، که  ویروس ها را به یکی از هفت گروه تقسیم بندی میکنند.


طبقه بندی بر اساس ژنوم (سیستم بالتیمور)

  • I: dsDNA viruses (e.g. Adenoviruses, Herpesviruses, Poxviruses)

  • II: ssDNA viruses (+)sense DNA (e.g. Parvoviruses)

  • III: dsRNA viruses (e.g. Reoviruses)

  • IV: (+)ssRNA viruses (+)sense RNA (e.g. Picornaviruses, Togaviruses)

  • V: (−)ssRNA viruses (−)sense RNA (e.g. Orthomyxoviruses, Rhabdoviruses)

  • VI: ssRNA-RT viruses (+)sense RNA with DNA intermediate in life-cycle (e.g. Retroviruses)

  • VII: dsDNA-RT viruses (e.g. Hepadnaviruses)
