Novel polyomaviruses in South American bats and their relationship to other members of the family Polyomaviridae.

چکیده
Bats are the natural reservoir of a variety of viruses, including a polyomavirus (PyV) from a North American brown bat. We investigated 163 spleen samples from 22 bat species from French Guiana for the presence of PyVs. In total, we detected 25 PyV-positive animals belonging to nine different bat species. Phylogenetic analysis was performed on the genomes of eight representative PyVs, and showed that the bat PyVs form three distinct lineages within the genus Orthopolyomavirus and are genetically different from the previously described North American bat virus. Interestingly, two lineages cluster with PyVs found in chimpanzees, orangutans and gorillas. In addition, one group of bat PyVs is genetically related to the human Merkel cell polyomavirus.

Review on the Relationship between Human Polyomaviruses-Associated Tumors and Host Immune System
The polyomaviruses are small DNA viruses that can establish latency in the human host. The name polyomavirus is derived from the Greek roots poly-, which means "many," and -oma, which means "tumours." These viruses were originally isolated in mouse (mPyV) and in monkey (SV40). In 1971, the first human polyomaviruses BK and JC were isolated and subsequently demonstrated to be ubiquitous in the h...
متن کاملThe Rapidly Expanding Family of Human Polyomaviruses: Recent Developments in Understanding Their Life Cycle and Role in Human Pathology
Since their discovery in 1971, the polyomaviruses JC (JCPyV) and BK (BKPyV), isolated from patients with progressive multifocal leukoencephalopathy and polyomavirus-associated nephropathy, respectively, remained for decades as the only known members of the Polyomaviridae family of viruses of human origin. Over the past five years, the application of new genomic amplification technologies has fa...
متن کاملCharacterization of a Novel Polyomavirus Isolated from a Fibroma on the Trunk of an African Elephant (Loxodonta africana)
Viruses of the family Polyomaviridae infect a wide variety of avian and mammalian hosts with a broad spectrum of outcomes including asymptomatic infection, acute systemic disease, and tumor induction. In this study a novel polyomavirus, the African elephant polyomavirus 1 (AelPyV-1) found in a protruding hyperplastic fibrous lesion on the trunk of an African elephant (Loxodonta africana) was ch...
متن کاملPolyomavirus-Associated Progressive Multifocal Leukoencephalopathy (PML) in HAART era
Polyomaviruses may cause human disease, particularly in immunocompromised hosts. JCV, one of the members of polyomaviridae family, is the causative agent of the neurological disease progressive multifocal leukoencephalopathy (PML), which occurs mostly in immunocompromised patients. Progressive Multifocal leukoencephalopathy (PML) is a progressive demyelinating disorder of the central nervous sy...
متن کاملDiscovery of diverse polyomaviruses in bats and the evolutionary history of the Polyomaviridae.
Polyomaviruses (PyVs) have been identified in a wide range of avian and mammalian species. However, little is known about their occurrence, genetic diversity and evolutionary history in bats, even though bats are important reservoirs for many emerging viral pathogens. This study screened 380 specimens from 35 bat species from Kenya and Guatemala for the presence of PyVs by semi-nested pan-PyV P...
