Difference between Bacteriophage and TMV (TMV vs Bacteriophage)

Bacteriophage are viruses which are obligate parasites on bacteria.  They were discovered by Twort and d Herelle. These are tadpole shaped viruses and contain a single stranded DNA, ds DNA, ssDNA, ds DNA as genetic material. 

TMV (Tobacco Mosaic Virus) is the most serious pathogen causing on tobacco leaves. It is transmitted by artificial inoculation but not by insect vectors. This is the first virus that crystallized in 1935 by W M Stanely in the USA 

Bacteriophage vs TMV (Tobacco Mosaic Virus)

Bacteriophage:

1. Shape: Tadpole like with  head and tail

2. Symmetry: Head cuboidal and tail helical

3. Nucleic acid: Nucleoid DNA or RNA

4. Adsorption: Adsorption over host cell is highly specific and complex.

5. Phagocutosis:  The virus is not taken inside the host cells by phagocytosis

6. Intercellular virion: Only DNA portion enters the host cell and is termed intercellular virion

7. Separation: Protein coat and nucleic acids are separated outside the host cell.

8. Lysis: After eliciple phase lysis of host cell takes place.

9. Prophage: Prophage condition is present.

TMV(Tobacco Mosaic Virus)

1. Shape: rod shaped

2. Symmetry: helical symmetry

3. Nucleic acid: nucleioid RNA

4. Adsorption: adsorption over host cell is simple

5. Phagocytosis: the virus is taken inside the host cell by phagocytosis.

6. Intracellular virion: the entire virus enters into the host cell.

7. Separation: protein coat and RNA are separated inside the host cell

8. Lysis: The host cell after eclipse phase ma or may not lyse.

9. Prophage: No prophage condition preset.
