The recent discovery of virophages associated with Mimivirus further stimulates the debate over its classification as a cellular microorganism or a virus. The fact that other smaller viruses can infect Mimivirus is a true testament to its size relative to other viruses.
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.
