What is Papovavirus?
The Papovaviridae family of viruses contains the papilloma viruses, which are associated with warts on the skin and mucous membranes. The name of the family is derived from the first virus discovered in this group, Papova virus. Papovavirus – Definition Structure Classification and Treatment.
Structure of Papovavirus
Papovaviruses are a family of DNA viruses that cause tumors in animals. The name papovavirus is derived from the first member of the family to be discovered, the papilloma virus (PV), which causes warts on the skin. There are three genera in the family: papilloma virus, polyoma virus, and simian virus 40 (SV40).
Papovaviruses are small, icosahedral viruses with a diameter of about 18-20 nm. They have a double-stranded DNA genome of about 8,000 base pairs. The viral DNA is organized into a circular chromosome and two extrachromosomal DNA molecules.
Papovaviruses are enveloped viruses with a lipid bilayer membrane. The viral envelope contains two glycoproteins, gp120 and gp41. These glycoproteins are responsible for virus attachment and entry into the host cell.
Papovaviruses are spread by contact with infected tissues or fluids. They enter the host cell by binding to the cell surface glycoproteins gp120 and gp41. The virus is then internalized into the cell and the viral DNA is released into the cytoplasm. The viral DNA is then transported to the nucleus where it hijacks the host cell’s replication machinery to produce new virus particles.
Classification and Antigenic Types of Papovavirus
There are three antigenic types of papovavirus:
Papillomavirus (HPV) types 6 and 11 cause benign warts on the skin.
They are also the most common types of HPV that cause genital warts.
Papovavirus type 16 causes cervical cancer.
Papovavirus type 18 causes most cases of anal cancer.
Multiplication of Papovavirus
Papovaviruses are a large family of DNA viruses that can cause tumors in a variety of organs. The most common members of this family are the human papillomaviruses (HPVs), which cause cervical cancer and other cancers of the reproductive tract. Other members of the papovavirus family include the polyoma viruses, which cause tumors in a variety of organs, including the brain, and the papovavirus BK, which can cause serious kidney disease.
Host Defenses of Papovavirus
The host defenses of Papovavirus are mainly cell-mediated. The virus is able to enter the cells, but cannot replicate without the help of the cellular machinery. The virus proteins are recognized by the host’s immune system, and the infected cells are destroyed. In addition, the body’s natural killer cells and cytotoxic T cells are able to recognize and destroy the virus-infected cells.
Epidemiology of Papovavirus
Papovaviruses are a group of small DNA viruses that cause a variety of diseases in humans, including cancer. The most common papovavirus is the human papillomavirus (HPV), which is responsible for the majority of cervical cancers. Other papovaviruses include the polyomaviruses and the papillomaviruses of animals.
What is Human Papovavirus?
HPV is a human papillomavirus, a virus that can cause cervical cancer and other cancers. HPV is the most common sexually transmitted infection (STI) in the United States. HPV is spread through sexual contact.
Papovavirus Treatment & Management
There is currently no specific treatment or management protocol for papovavirus infections. Treatment is generally supportive, and may include fluids, rest, and pain relief. Some cases of papovavirus infections may require hospitalization.
Summary
This study found that there was a significant decrease in the number of days to resolution of symptoms for both the intervention and control groups. However, the difference between the groups was not statistically significant. Papovavirus – Definition Structure Classification and Treatment.
