Novel Polyomaviruses in Mammals from Multiple Orders and Reassessment of Polyomavirus Evolution and Taxonomy.

As the phylogenetic organization of mammalian polyomaviruses is complex and currently incompletely resolved, we aimed at a deeper insight into their evolution by identifying polyomaviruses in host orders and families that have either rarely or not been studied. Sixteen unknown and two known polyomaviruses were identified in animals that belong to 5 orders, 16 genera, and 16 species. From 11 novel polyomaviruses, full genomes could be determined.

Genome Sequences of Polyomaviruses from the Wild-Living Red Colobus (Piliocolobus badius) and Western Chimpanzee (Pan troglodytes verus).

We identified with PCR and sequencing the full genomes of the recently discovered Pan troglodytes verus polyomavirus 8 and Piliocolobus badius polyomavirus 2 in a western chimpanzee and a western red colobus free-ranging in Taï National Park of Côte d'Ivoire.

Genome Sequence of Bovine Polyomavirus 1 Detected in a Salers Cow (Bos taurus) from Catalonia, Spain.

We identified a variant of the first bovine polyomavirus (BPyV1; family Polyomaviridae) in a lymph node of a Salers cow. As the 2 previously published genome sequences of this virus originated from fetal bovine serum and ground beef, respectively, this is the first BPyV1 genome that could be traced back to an individual.

Genome Sequences of Murine Pneumotropic Virus (Polyomaviridae) Detected in Wild House Mice (Mus musculus).

Using generic PCR, we identified a variant of murine pneumotropic virus (MptV) (family Polyomaviridae) in 3 wild house mice (Mus musculus). The fully amplified and sequenced genomes display considerable differences from the MptV genomes published previously and enlighten us on the natural diversity of rodent polyomaviruses.
