Life Cycles of Lambda: Lytic and Lysogenic | Microbiology

Lambda consists of two types of life cycles, the lytic and lysogenic. Lytic Cycle: The events of lytic cycle, starting with adsorption, at 37°C occurs as below: Time (t) = 0 minutes: Phage adsorbed and DNA is injected = 3 minutes: First early mRNA is synthesized = 5 minutes: Two classes of early mRNA are synthesized = 6 minutes: DNA [...]

6 Main Therapies of Bacteriophage | Microbiology

The following points highlight the six main therapies of bacteriophages. The therapies are: 1. Collection 2. Mode of Action of Phage Preparations 3. Commercial Production of Phages 4. Prophylaxis and Treatment of Bacterial Infections 5. Characteristics of Bacterlophages 6. Bio-Safety. Therapy # 1. Collection: Local samples of bacteriophage can be collected from water which possibly contains high quantities of bacteria [...]

Cyanophages: Morphology and Growth Cycle | Microbiology

In this article we will discuss about the morphology and growth cycle of cyanophages. Cyanophages are the viruses that attack on cyanobacteria i.e. members of the blue-green algae in general. For the first time Safferman and Morris (1963) isolated a virus from the waste stabilization pond of Indiana University (U.S.A) that attacked and destroyed the three genera: Lyngbya, Plectonema and [...]
