Bacteriophage phage are obligate intracellular viruses that specifically infect bacteria. Phage have a very simple structure Figure 1. Their genetic material is contained in a prism shaped head, surrounded by a protein capsid.

Viruses are often very specific as to which hosts and which cells within the host they will infect. This feature of a virus makes it specific to one or a few species of life on earth. So many different types of viruses exist that nearly every living organism has its own set of viruses that try to infect its cells. Even the smallest and simplest of cells, prokaryotic bacteria, may be attacked by specific types of viruses. Bacteriophage : This transmission electron micrograph shows bacteriophages attached to a bacterial cell. Bacteriophages are viruses that infect bacteria.

Some viruses i'll stress here Herpes viruses can undergo 2 life cycles; lysogenic and lytic cycle. Now, let us look at the lytic cycle first. Lytic Cycle In one hand, the lytic cycle is a mode of viral reproduction wherein the goal is to produce virions and as a result, the lysis of the host cell. Viruses do not have structures that can support self-reproduction. Hence, they use the host cell's structures to help the virus replicate itself. Recall that viruses infect host cells by injecting their genetic material to the host's DNA. The DNA encodes what the cell should produce.

What are the differences between a lytic infection and a lysogenic infection?

Major Differences. A 'difference between' Site. Difference between Lysogenic phase and Lytic phase. The multiplication process of temperate phage is called Lysogenic cycle and the multiplication of virulent phage is called lytic cycle. Lysogenic vs Lytic phase Lysogenic vs Lytic phase. The host DNA is not hydrolysed during lysogenic phase.

Difference Between Lytic Cycle and Lysogenic Cycle

Lysogeny , or the lysogenic cycle , is one of two cycles of viral reproduction the lytic cycle being the other. Lysogeny is characterized by integration of the bacteriophage nucleic acid into the host bacterium's genome or formation of a circular replicon in the bacterial cytoplasm. In this condition the bacterium continues to live and reproduce normally. The genetic material of the bacteriophage, called a prophage , can be transmitted to daughter cells at each subsequent cell division, and at later events such as UV radiation or the presence of certain chemicals can release it, causing proliferation of new phages via the lytic cycle. The difference between lysogenic and lytic cycles is that, in lysogenic cycles, the spread of the viral DNA occurs through the usual prokaryotic reproduction, whereas a lytic cycle is more immediate in that it results in many copies of the virus being created very quickly and the cell is destroyed. One key difference between the lytic cycle and the lysogenic cycle is that the lysogenic cycle does not lyse the host cell straight away. In the lysogenic cycle, the phage DNA first integrates into the bacterial chromosome to produce the prophage.
