POLYOMAVIRUS . De två viktigaste typerna av polyomavirus, BK-virus och JC-virus är mycket vanliga i befolkningen och orsakar vanligen inte sjukdom hos immunkompetenta. Efter organtransplantation, särskilt efter stamcellstransplantation och njurtransplantation, kan BK-virusinfektion ge problem med hemorragisk cystit och nefropati.

Human polyomavirus 2, commonly referred to as the JC virus or John Cunningham virus, is a type of human polyomavirus (formerly known as papovavirus). It was identified by electron microscopy in 1965 by ZuRhein and Chou, and by Silverman and Rubinstein, and later isolated in culture and named using the two initials of a patient, John Cunningham, with progressive multifocal leukoencephalopathy

Mer info. Länk till extern anvisning. Övrigt- 2021-04-07 · Polyomavirus är en grupp av små DNA-virus. De humana polyomavirusen BK- och JC-virus infekterar merparten av befolkningen, och en livslång latent infektion uppstår. De är ofarliga så länge immunförsvaret är intakt men kan hos immunsupprimerade orsaka svår sjukdom och i värsta fall döden. BK-virus är ett dubbelsträngat DNA -virus med cirkulärt genom som tillhör familjen polyomavirus. Viruset sprids från människa till människa, men exakt hur det sprids är ännu inte känt.

Polyomavirus

Therapy for polyomavirus infection is still evolving. No prospective studies have been done to determine whether subjects with asymptomatic viruria benefit from specific therapeutic intervention. However, patients diagnosed promptly by protocol biopsies show better graft survival than patients in whom diagnosis is made after clinically obvious graft dysfunction. [18] Se hela listan på talk.ictvonline.org Polyomavirus, the renal disease manifestations of which have already been discussed, is usually acquired at an early age. Clinical manifestations of polyomavirus occur only with immunosuppression, such as after bone marrow transplantation, and can include cystitis and hematuria. polyomavirus A small icosahedral, double-stranded oncogenic DNA virus of the Papovaviridae family, which may be used to induce experimental tumours in mice.

In 2008 we identified a novel polyomavirus in Merkel cell carcinoma (MCC) tissues (Feng, Shuda et al. 2008).

Polyomaviruses are small, nonenveloped DNA viruses, which are widespread in nature. In immunocompetent hosts, the viruses remain latent after primary

They are found in urine, feces and wastewater as a Pathogen name and classification. BK virus is a polyomavirus in the Papovaviridae family. The human polyomaviruses are JC, WU, KI, MW, STL, TS, Aug 8, 2019 However, of these 80 described Polyomaviruses, only 13 species have been identified to infect humans (3, 4), notably JCPyV, BKPyV, SV40, Polyomavirus Basics.

Lymphotropic polyomavirus (LPV), another monkey polyomavirus, may also infect man as specific antibodies against the major capsid protein VP1 were present in 15% of the blood samples from healthy individuals, and LPV DNA has been detected in blood of immunosuppressed and healthy subjects [9–11]. Define polyomavirus.

In all observed cases, activation of either JCV and BKV in immunosuppressed patients has resulted in fatality. Polyomavirus.

However, significant clinical manifestations are rare and limited to individuals with impaired immune functions. BKV has been associated with diverse entities such as haemorrhagic cystitis, ureteric stenosis, vasculopathy, pneumonitis, encephalitis, retinitis, and even multi–organ failure.
