MSH: Genus of non-oncogenic retroviruses which establish persistent infections in many animal species but are considered non-pathogenic. Its species have been isolated from primates (including humans), cattle, cats, hamsters, horses, and sea lions. Spumaviruses have a foamy or lace-like appearance and are often accompanied by syncytium formation. SIMIAN FOAMY VIRUS is the type species.,NCI: Genus of retroviruses which establish persistent, but non pathogenic infections in mammals and primates, including humans, chimpanzees, cattle, and cats. It is unique among retroviruses in having infectious particles that carry DNA rather than RNA. Similar to hepadnaviruses, spumaviruses bud from the endoplasmic reticulum instead of the plasma membrane. Infected cells accumulate vacuoles, giving them a foamy appearance and are often involved in syncytium formation.
