â30th and Main,â I replied. It was the home of one of Arielleâs book club friends, who Iâd overheard planning to âsurprise her.â Iâd never been there before, but with a little help of the internet I could easily figure out where her friend lived. Fox nodded and switched his car into gear.
bacteriophage. A bacteriophage is a type of virus that infects bacteria. In fact, the word bacteriophage literally means bacteria eater, because bacteriophages destroy their host cells.All bacteriophages are composed of a nucleic acid molecule that is surrounded by a protein structure.ventually, new bacteriophages assemble and burst out of the bacterium in a process called lysis. Bacteriophages occasionally remove a portion of their host cells' bacterial DNA during the infection process and then transfer this DNA into the genome of new host cells. This process is known as transduction.
Viral Infection Types. Animal viruses cause various types of infection. In lytic infections, the virus will break open or lyse the host cell, resulting in the destruction of the host cell. Other viruses may cause persistent infections.In this type of infection, the virus may go dormant and be reactivated at a later time. The host cell may or may not be destroyed. Some viruses can cause persistent infection in different organs and tissues at the same time.iruses gain entry into host cells via several sites such as the skin, gastrointestinal tract, and respiratory tract. Once an infection has occurred, the virus may replicate in host cells at the site of infection or they may also spread to other locations.
