**(CONCISE NOTES)** **[Classification of viruses]** - It is the structure based classification of viruses proposed by International Committee on Taxonomy of Viruses (ICTV). In 1966, International Committee on Nomenclature of Viruses (ICNV) was established and renamed as ICTV in 1974. - ICTV is assigned with the task of a universal taxonomic scheme for all the viruses infecting animals, plants, fungi, bacteria *etc*. **[Baltimore classification]** - Baltimore classification of viruses is based on the messenger RNA synthesis. - There are **seven groups** under which viruses are classified. These are listed below. - **Group-I: Double-stranded DNA viruses** - **Group II: Single-stranded DNA viruses** - **Group III: Double-stranded RNA viruses** - **Group IV: Single-stranded RNA viruses (Positive sense)** - **Group V: Single-stranded RNA viruses (Negative sense)** - **Group VI: Single-stranded RNA viruses with a DNA intermediate in their life cycle** - **Group VII: Double-stranded DNA viruses with an RNA intermediate in their life cycle** \*\*\*\*\*\*
