	Polyomavirus - Wikipedia, the free encyclopedia
		Polyomavirus is the sole genus of viruses within the family Polyomaviridae.
		There are two polyomaviruses found in humans: JC virus, which can infect the respiratory system, kidneys, or brain (sometimes causing the fatal progressive multifocal leukoencephalopathy in the latter case), and BK virus, which produces a mild respiratory infection and can affect the kidneys of immunosuppressed transplant patients.
		An avian polyomavirus sometimes referred to as the Budgerigar fledgling disease virus is a frequent cause of death among caged birds.

	Polyomaviruses, JC Virus, BK Virus
		JC was first isolated from the brain from a patient suffering from Hodgkin's disease, and suffering from PML.
		Polyomavirus replication in permissive cells can be detected by observing CPE or plaque production, by identifying virus particles in cell or culture fluid by EM, by detecting virus antigens using IF, or by observing haemagglutination.
		JC and BK viruses are ubiquitous throughout the world, and the 2 viruses circulate independently.

	JC virus - Wikipedia, the free encyclopedia
		JC virus or JC polyomavirus is a type of human polyomavirus, genetically similar to BK virus and SV40.
		It was discovered in 1971 and named after the initials of the person in whom it was found, a patient with progressive multifocal leukoencephalopathy.
		Studies since 2000 have found JC virus in malignant colon tumors and suggested that the virus may be linked to colon cancer.

		A polyomavirus known as simian virus 40 (SV40) was introduced into humans through contaminated poliovirus and adenovirus vaccines in use before 1963, at which time, ~90% of children and ~60% of adults received contaminated poliovirus vaccination (cf.#3).

	Emerging Worlds: Chronic Illness and Viral Infections
		The avian polyomavirus referred to as BFDV by the ICTV is not a single entity; three distinct viruses can be distinguished based on DNA sequence analysis and clinical studies, and these three viruses are designated BFDV 1–3 (10).
		The fact that polyomavirus DNA is sometimes found in an episomal manner in tumor tissue is reminiscent of the situation with human papillomavirus strain 16 (HPV-16).
		The main difficulties in establishing a polyomavirus as an etiologically significant factor in human cancer causation are similar to those that were encountered in studies of cancer induction by HPV (reviewed in Ref. 3,116).

	CBER - Simian Virus 40 (SV40:) A Possible Human Polyomavirus Workshop
		Two patients with progressive multi focal leukoencephalopathy, a disease we heard about yesterday known to be associated with the JC virus, and born in 1915 and 1933, had SV40 isolated from their brains by techniques that are still reliable.
		Again, the purpose of this was to see whether the mesothelioma population as a whole had some difference from a normal population with regard to neutralizing antibodies of T-antigen, and the data is graphically depicted here with the normal volunteers at the bottom and at the top.
		Small parts of SV40 put into JC might make JC a bit more active, maybe more tumorigenic, but it might be difficult also to define those SV40 sequences in those JCs unless you do a lot of sequencing.

		Although the BK subtype of polyomavirus was first isolated from the urine of a renal transplant recipient in 1971, recognized infection was rare until recently.
		Because the histological picture is similar to that in acute rejection and polyomavirus interstitial nephritis can coexist with acute rejection, some patients have undergone treatment for acute rejection along with intensification of their maintenance immunosuppression.
		JC polyomavirus is the etiologic agent for progressive multifocal leukoencephalopathy, a disorder of immunocompromised patients characterized by cerebral white matter defects with cortical blindness, hemiparesis, dementia, coma, and death within 6 months.

		The age and gender of the Biaka and Bantu adults tested for JC viruria is given in the Table.
		We conclude that human polyomavirus JCV is excreted in the urine of Biaka Pygmies and Bantus of central Africa, though at a lower rate than that observed in other population groups.
		The finding of four different subtypes of JCV in the urine of Biaka Pygmies may be explained by the extensive interactions of Pygmies with their various African tribal neighbors over a long period of time, as they moved from place to place in the equatorial forest.

		Researchers from Temple University, Philadelphia, USA have confirmed a link between the common JC polyomavirus and the development of malignant brain tumours of childhood — medulloblastomas.
		The human polyoma JC virus (JCV) has received particular attention for its role in a rare, but usually fatal demyelinating disease of the brain known as progressive multifocal leukoencephalopathy (PML), which affects individuals with defective cell-mediated immune responses, such as in AIDS.
		The authors conclude that, ‘the finding of agnoprotein expression in the absence of T antigen expression suggests a potential role for agnoprotein in pathways involves in the development of JCV-associated medullablastomas’.
