The DNA of viruses is stored in capsids, or packing proteins that facilitate the formation of the virus particle. I can't see how this could be related to nucleosomes (which is the DNA wrapped around the histone complex twice)
The same holds for bacteria - although there are proteins that surely bind to their DNA, there is no such equivalent as the nucleosome. Although some 'histone-like' protiens DO exist in bacteria.
