Polyomaviridae is a family of viruses whose natural hosts are primarily mammals and birds. [1] [2] As of 2024, there are eight recognized genera. [3]Fourteen species are known to infect humans, while others, such as Simian Virus 40, have been identified in humans to a lesser extent.
Water virology started about half a century ago when scientists attempted to detect the polio virus in water samples. [3] Since then, other pathogenic viruses that are responsible for gastroenteritis, hepatitis, and many other virus strains have replaced enteroviruses as the main aim for detection in the water environment. [3]
The virus is very common in the general population, infecting 70% to 90% of humans; most people acquire Human polyomavirus 2 in childhood or adolescence. [22] [23] [24] It is found in high concentrations in urban sewage worldwide, leading some researchers to suspect contaminated water as a typical route of infection. [8]
Very widespread, can manifest itself in water, ~80% of the population has antibodies to Polyomavirus BK virus produces a mild respiratory infection and can infect the kidneys of immunosuppressed transplant patients. JC virus infects the respiratory system, kidneys or can cause progressive multifocal leukoencephalopathy in the brain (which is ...
The BK virus, also known as Human polyomavirus 1, is a member of the polyomavirus family. Past infection with the BK virus is widespread, [1] but significant consequences of infection are uncommon, with the exception of the immunocompromised and the immunosuppressed. BK virus is an abbreviation of the name of the first patient, from whom the ...
The primary alphapolyomavirus that is of clinical significance to humans is Merkel cell polyomavirus (Human polyomavirus 5, MCV, or MCPyV). The apparent oncogenicity of MCPyV [6] similar to other cancer-causing viruses such as HPV, Epstein-Barr virus, and Hepatitis C virus [7] is a main area of research for the scientific community.
Murine polyomavirus VP1 in complex with the GT1a glycan. GT1a is shown in yellow and the VP1 monomer with a white surface and a blue protein backbone. A complex network of hydrogen bonds, many water-mediated, is shown at the binding surface by orange lines, with participating protein residues shown as sticks. Mutations of the two residues shown ...
The circular genome of a representative polyomavirus, WU polyomavirus, with the late region at right indicating positions of the VP1, VP2, and VP3 genes. [4]All three capsid proteins are expressed from alternative start sites on a single transcript of the "late region" of the circular viral chromosome (so named because it is transcribed late in the process of viral infection).
