A novel polyomavirus from the nasal cavity of a giant panda (Ailuropoda melanoleuca)

Virology Journal, 2017
Background Polyomaviruses infect a wide variety of mammalian and avian hosts with a broad spectrum of outcomes including asymptomatic infection, acute systemic disease, and tumor induction.

Polyomavirus-associated nephropathy

World Journal of Transplantation, 2012
Polyomaviruses BK and JC are ubiquitous viruses with high seroprevalence rates in general population. Following primary infection, polyomaviruses BK and JC persist latently in different sites, particularly in the reno-urinary tract. Reactivation from latency may occur in normal subjects with asymptomatic viruria, while it can be associated to ...

Brincidofovir inhibits polyomavirus infection in vivo

mBio
Polyomaviruses are species-specific DNA viruses that can cause disease in immunocompromised individuals. Despite their role as the causative agents for several diseases, there are no currently approved antivirals for treating polyomavirus infection ...

Merkel Cell Carcinoma With Divergent Differentiation—Or Something Else? A Triphasic Cutaneous Carcinoma With Lineage Plasticity

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Merkel cell carcinoma (MCC) is a rare, aggressive cutaneous neuroendocrine carcinoma that typically arises in sun‐exposed skin of older or immunosuppressed patients. Combined or collision tumors involving MCC and other cutaneous malignancies are uncommon, and tumors exhibiting more than two distinct malignant phenotypes are exceptionally rare.

Absence of DNA viruses in ameloblastomas

European Journal of Oral Sciences, EarlyView.
Abstract Ameloblastomas (ABs) are rare odontogenic benign tumors. Although studies of the molecular pathogenesis have revealed the presence of mutations and altered gene expression, the etiology is unresolved. Viruses cause 10%–15 % of cancers, but their potential role within benign tumors is less studied.

A Divergent Variant of the Eleventh Human Polyomavirus Species, Saint Louis Polyomavirus [PDF]

Genome Announcements, 2013
ABSTRACT Saint Louis polyomavirus (STLPyV) was recently discovered in human feces. Using random-primed rolling circle amplification combined with deep sequencing, we have found a divergent variant of STLPyV in a sanitized human skin wart specimen.

Detection of polyomavirus microRNA-5p expression in saliva shortly after kidney transplantation

Journal of Oral Microbiology, 2021
Background: MicroRNAs (miRNAs) of polyomavirus (PyV) are present in several biological fluids and are suggested to be relevant viral factors for monitoring its persistence.

Recipient–Donor Sex Combinations and Posttransplant Infections: A Swiss Transplant Cohort Study

Transplant Infectious Disease, EarlyView.
In this cohort study of 5033 patients, only the recipient sex, in particularly kidney recipients, was independently associated with an increased risk of infections, when compared to males. These findings indicate that recipient–donor sex combination does not influence short‐term solid organ transplantation outcome.

JC Polyomavirus Uses Extracellular Vesicles To Infect Target Cells

mBio, 2019
The endemic human JC polyomavirus (JCPyV) causes progressive multifocal leukoencephalopathy in immune-suppressed patients. The mechanisms of virus infection in vivo are not understood because the major target cells for virus in the brain do not express ...

Complex Virome in a Mesenteric Lymph Node from a Californian Sea Lion (Zalophus californianus) with Polyserositis and Steatitis

Viruses, 2020
An emaciated subadult free-ranging California sea lion (Csl or Zalophus californianus) died following stranding with lesions similar to 11 other stranded animals characterized by chronic disseminated granulomatous inflammation with necrotizing steatitis ...
