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 [...]
In this article we will discuss about Bacteriophage:- 1. Introduction to Bacteriophage 2. Morphology of Bacteriophage 3. Life Cycle 4. Significance. Introduction to Bacteriophage: Bacteriophage (Greek phagein—to eat; bacteriophage, bacteria-cater) are viruses that infect and parasitise bacteria. They cause lysis of bacteria. They are abbreviated as phages. Twart (1915) and d'Herelle (1917) observed an invisible minute parasite of bacteria that [...]
The below mentioned article provides a Practical Experiment on Culturing of Lambda (λ) Phage. Principle: Bacteriophage λ is cultured in E.coli cell suspension. The phage is allowed to harbour and multiply till the complete lysis of bacterial cells. Then the bacterial cells are killed with chloroform and the phage particles are separated by centrifugation. Materials: A. E. coli LE 392 [...]
