The life cycle of bacteria consists of four main phases: the lag phase, the exponential or log phase, the stationary phase and the death phase. Factors that trigger bacteria growth heavily rely on this life cycle. Bacteria multiply through a process known as binary fission. During the lag phase, bacteria do not grow.


Virus - The cycle of infection: Viruses can reproduce only within a host cell. The parental virus (virion) gives rise to numerous progeny, usually genetically and structurally identical to the parent virus. The actions of the virus depend both on its destructive tendencies toward a specific host cell and on environmental conditions. In the vegetative cycle of viral infection, multiplication of ...


Bacterial Life Cycle or Bacterial Cell Cycle: Bacterial life cycle mainly involves binary fission. In some cases budding and sporulation noticed. But genetic recombination, so called sexual reproduction in bacteria is an occasional process.


The bacteria life cycle consists of the lag phase, the log or exponential phase, the stationary phase and the death phase. Factors that influence bacterial growth bear heavily on this cycle. Lag Phase. Bacteria do not grow during the lag phase. However, they do adjust to their environment and metabolize, that is, produce vitamins and amino ...


Bacterial growth is the asexual reproduction, or cell division, of a bacterium into two daughter cells, in a process called binary fission.Providing no mutational event occurs, the resulting daughter cells are genetically identical to the original cell. Hence, bacterial growth occurs.


Some bacteria are destructive and cause various diseases like: – pneumonia, malaria etc. Not all bacteria are harmful. A few of them lend a helping hand as well. The Life Cycle of Bacteria is quite simple. Life Cycle of Bacteria: – There are four main phases in the life cycle of bacteria: – The Lag Phase: – In this phase, bacteria do ...

Start studying infection cycle. Learn vocabulary, terms, and more with flashcards, games, and other study tools.


At this point they initiate the reproductive cycle, resulting in lysis of the host cell. As the lysogenic cycle allows the host cell to continue to survive and reproduce, the virus is replicated in all of the cell’s offspring. An example of a bacteriophage known to follow the lysogenic cycle and the lytic cycle is the phage lambda of E. coli.


1-8. CYCLE OF INFECTION Prevention and control of infection is of vital importance to the patient as well as to health care personnel. In order to provide proper care for patients with communicable diseases or infectious organisms, you should understand the components of infection and the methods to control the cycle of infection.
