Papovaviruses

HPV

This group of viruses has the ability to transform cells and is related to tumor growth. We divide this family into two genera:

• Papillomavirus – the cause of warts and tumor growth
• Polyomavirus

Virion

The size of the virion is between 40–60 nm

Human papilloma virus (HPV)

• Together with other factors of the external environment, it is related to the development of cancer of the cervix uteri.
• According to oncogenic potential, the virus is divided into two types:
  • high risk HPV (16, 18, 45, 46),
  • low risk HPV (6, 11, 42–44).

• Transmission – through sexual contact (it does not manifest itself clinically in men).

Wart Virus

• It occurs more often in immunosuppressed people
• There is a possibility of treatment with ointments with inducers of interferons

Polyomaviruses

BK polyomavirus

• Significantly expanded, isolated from the urine of patients after kidney transplantation and with multifocal leukoencephalopathy.

JC polyomavirus

• Repeatedly isolated from the brain of patients who died of progressive multifocal leukoencephalopathy.
