The polyomavirus of pet birds belongs to the family Papovavirus, the same group of viruses that causes benign skin tumors (papillomas or warts) in birds. Polyomavirus can cause benign feather lesions in budgies (the so-called French molt or Budgerigar Fledgling disease) or acute death. Murine polyomavirus was the first polyomavirus discovered, having been reported by Ludwik Gross in 1953 as an extract of mouse leukemias capable of inducing parotid gland tumors. The causative agent was identified as a virus by Sarah Stewart and Bernice Eddy , after whom it was once called "SE polyoma". JC polyomavirus (JCPyV) is the causative agent of a fatal central nervous system demyelinating disease known as progressive multifocal leukoencephalopathy (PML). PML occurs in people with underlying immunodeficiency or in individuals being treated with potent immunomodulatory therapies.
Sitt namn polyoma har det fått av dess förmåga att producera en mängd tumörer. Merkel cell polyomavirus was first described in January 2008 in Pittsburgh, Pennsylvania. It was the first example of a human viral pathogen discovered using unbiased metagenomic next-generation sequencing with a technique called digital transcriptome subtraction. MCV is one of seven currently known human oncoviruses. It is suspected to cause the majority of cases of Merkel cell carcinoma, a rare but aggressive form of skin cancer. Approximately 80% of Merkel cell carcinoma tumors Ett vanligt symptom är hemmoragisk cystit, men även njurpåverkan av varierande allvarlighetsgrad förekommer. BK-virus har påträffats i en rad maligna tumörer som glioblastom meningeom och osteogent sarkom.
