In this article we will discuss about the structure of bacteriophage. Bacteriophage ØX174 belongs to the genus Micro virus of the family Microviridae from the Group II (ssDNA Viruses). The bacteriophage ØX174 was discovered by R.L. Sinsheimer at California Institute of Technology. It is one of the ssDNA phages of E.coli which has been most extensively studied. The phage particles [...]
In this article we will discuss about the classification of bacteriophage. 1. Bacteriophages with DNA Genome: A. Genome is double-stranded DNA, generally linear. 1. Family Myoviridae: Icosahedral, isometric or elongated head with a helical rigid tail containing a contractile sheath, tail plate, tail fibres and spikes. Example: E. coli phage (coliphage) T2, T4, T6. 2. Family Styloviridae: Icosahedral, isometric head [...]
In this article we will discuss about bacteriophage and its properties. The virus which infects and destroys the bacterial cell is known as bacteriophage or eater of bacterium (Greek phagein — to eat). Though they are so called, but they do not eat bacteria. They infect and destroy the bacterial cells only. They are commonly known as phages. The phages [...]
