چکیده

Phylogenetic analyses based on the major capsid protein sequence indicate that Merkel cell polyomavirus (MCPyV) and chimpanzee polyomaviruses (PtvPyV1, PtvPyV2), and similarly Trichodysplasia spinulosa-associated polyomavirus (TSPyV) and the orangutan polyomavirus (OraPyV1) are closely related. The existence of cross-reactivity between these polyomaviruses was therefore investigated. The findings indicated serological identity between the two chimpanzee polyomaviruses investigated and a high level of cross-reactivity with Merkel cell polyomavirus. In contrast, cross-reactivity was not observed between TSPyV and OraPyV1. Furthermore, specific antibodies to chimpanzee polyomaviruses were detected in chimpanzee sera by pre-incubation of sera with the different antigens, but not in human sera.

Genome Sequence of a Central Chimpanzee-Associated Polyomavirus Related to BK and JC Polyomaviruses, Pan troglodytes troglodytes Polyomavirus 1

We amplified and sequenced the genome of a polyomavirus infecting a central chimpanzee (Pan troglodytes troglodytes). This virus, which is closely related to BK and JC polyomaviruses, may help shed a new light on these human pathogens' evolutionary history.

African great apes are naturally infected with polyomaviruses closely related to Merkel cell polyomavirus.

The oncogenic Merkel cell polyomavirus (MCPyV) infects humans worldwide, but little is known about the occurrence of viruses related to MCPyV in the closest phylogenetic relatives of humans, great apes. We analyzed samples from 30 wild chimpanzees and one captive gorilla and identified two new groups of polyomaviruses (PyVs). These new viruses are by far the closest relatives to MCPyV described...

Novel Polyomaviruses of Nonhuman Primates: Genetic and Serological Predictors for the Existence of Multiple Unknown Polyomaviruses within the Human Population

Polyomaviruses are a family of small non-enveloped DNA viruses that encode oncogenes and have been associated, to greater or lesser extent, with human disease and cancer. Currently, twelve polyomaviruses are known to circulate within the human population. To further examine the diversity of human polyomaviruses, we have utilized a combinatorial approach comprised of initial degenerate primer-ba...

Association of Merkel Cell Polyomavirus–Specific Antibodies With Merkel Cell Carcinoma

BACKGROUND Merkel cell polyomavirus (MCPyV) has been detected in approximately 75% of patients with the rare skin cancer Merkel cell carcinoma. We investigated the prevalence of antibodies against MCPyV in the general population and the association between these antibodies and Merkel cell carcinoma. METHODS Multiplex antibody-binding assays were used to assess levels of antibodies against pol...

Updated Phylogenetic Analysis of Polyomavirus-Host Co- Evolution

Phylogenetic analysis of the mammalian and avian polyomaviruses was performed using the most complete set of publicly available polyomavirus genome sequences to date, including the newly discovered MW polyomavirus. There is no evidence for host-switching between mammalian and avian polyomaviruses, but there is extensive evidence for host-switching among mammalian polyomaviruses. Comparative gen...
