|Description:||This transmission electron microscopic (TEM) image revealed the presence of numerous icosahedral-shaped K viruses, each containing an inner, double-stranded DNA genomic core. K viruses are commonly found in humans, as well as other mammal species. This virus affects rodents including rats and mice, and causes pneumonia in very young mice.|
The term papovavirus is an archaic taxonomic term, which was a chimera of sorts, being created by having combined Papillomavirus, the Polyomavirus, and the simian vacuolating virus, or SV40 virus. Today, these viruses have been grouped into each appropriate Papillomaviridae and Polyomaviridae family.
