Bacteriophage types – Replication cycles & Classification. There are many bacteriophage types, although a few we hear of more than others. Bacteriophages are very complex viruses that have been around since the earliest Earth history and have played a crucial role in maintaining the balance over the population of bacteria on our planet.

Lytic cycle

Phages exhibit two different types of life cycle: · Lytic cycle: also known as virulent cycle. In this cycle, intra-cellular multiplication of the phage results in the lysis of host bacteria, resulting in release of progeny virions. The Lytic Cycle. During the lytic cycle of virulent phage, the bacteriophage takes over the cell, reproduces new phages, and destroys the cell. T-even phage is a good example of a well-characterized class of virulent phages.

Attachment: The T4 phage has a complex structure with several tail fibers. These fibers help in the …

Attachment stage- The virus attach itself to the host cell in a lock and key way. Penetration stage- The virus ''inject'' its DNA/RNA into the host cell.

Authors Jessica McKenzie 1 , Ayman El-Guindy 2 Affiliations 1 Department of Pediatrics, Division of The KSHV lytic cycle can ensue following primary infection or when a latently infected cell undergoes lytic reactivation. During the lytic cycle, a temporal transcriptional cascade begins that results in the expression of viral immediate-early, delayed-early, and late genes followed by the subsequent assembly and egress of progeny virions ( Sun et al., 1999 ). Two major cycles of multiplication of bacteriophages are : 1.

Virulent phages undergo only the lytic cycle. Temperate phages have two phases to their life cycles. The lysogenic cycle allows the genome of the virus to be

As soon as the cell is destroyed, the phage progeny can find new hosts to infect. An example of a lytic bacteriophage is T4, which infects E. coli found in the human intestinal tract. Lytic phages are more suitable The viral lytic cycle is an important process in oncolytic virotherapy. Most mathematical models for oncolytic virotherapy do not incorporate this process.
