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.
Viruses usually infect a specific type of cell, which causes viral infections to affect certain parts of the body. A cold is the most common type and generally affects the upper respiratory tract.Influenza is another common infection, but symptoms can affect the entire body. Ad.rinary tract infections are common bacterial infections that can be treated with antibiotics. Thorough hand washing can help prevent infections. Some infections require antibiotic therapy. Fungus is a common cause of infections, such as ringworm.
