Simian Foamy Virus Co-Infections.Foamy viruses (FVs), also known as spumaretroviruses, are complex retroviruses that are seemingly nonpathogenic in natural hosts.  In natural hosts, which include felines, bovines, and nonhuman primates (NHPs), a large percentage of adults are infected with FVs.  For this reason, the effect of FVs on infections with other viruses (co-infections) cannot be easily studied in natural populations.  Most of what is known about interactions between FVs and other viruses is based on studies of NHPs in artificial settings such as research facilities.  In these settings, there is some indication that FVs can exacerbate infections with lentiviruses such as simian immunodeficiency virus (SIV).  Nonhuman primate (NHP) simian FVs (SFVs) have been shown to infect people without any apparent pathogenicity.
