Spumaretrovirinae,commonly calledspumaviruses(spuma,Latinfor "foam" ) orfoamyviruses,is a subfamily of theRetroviridaefamily.[2]Spumaviruses areexogenousviruses that have specificmorphologywith prominent surfacespikes.Thevirionscontain significant amounts of double-stranded full-lengthDNA,and assembly is rather unusual in these viruses. Spumaviruses are unlike most enveloped viruses in that theenvelopemembrane is acquired bybuddingthrough theendoplasmic reticuluminstead of thecytoplasmic membrane.Some spumaviruses, including the equine foamy virus (EFV), bud from the cytoplasmic membrane.
Some examples of these viruses aresimian foamy virusand thehuman foamy virus.
While spumaviruses will form characteristic large vacuoles in their host cells whilein vitro,there is no disease associationin vivo.[3]
