A·re·na·vi·ri·dae

(ă'rē-nă-vir'i-dē),
A family of more than 15 RNA viruses, many of which are natural parasites of rodents, that includes lymphocytic choriomeningitis virus, Lassa virus, and the Tacaribe virus complex. The virions are 50-300 nm (average 100 nm) in diameter, enveloped, ether-sensitive, and contain two single-stranded RNA molecules (molecular weight 3-5 × 106); they also contain electron-dense, RNA-containing granules (20-30 nm in diameter) that resemble ribosomes, with an electron-microscopic appearance of sandiness.

Arenaviridae

a family of spherical or pleomorphic, enveloped, single-stranded RNA viruses containing host cell-derived ribosomes, e.g. Lassa fever virus, lymphocytic choriomeningitis (LCM) virus and Tacaribe viruses. The natural hosts are rodents.

Lymphocytic choriomeningitis virus (LCMV), an Old World arenavirus, family Arenaviridae, is a zoonotic virus maintained in the house mouse (Mus musculus) and can be carried by pet and laboratory rodents (1-7); human exposure occurs through aerosolized excreta or by direct rodent contact.
Tacaribe serocomplex viruses (family Arenaviridae, genus Arenavirus) comprise Bear Canyon virus, Tamiami virus, and Whitewater Arroyo virus in the United States; Tacaribe virus (TCRV) on Trinidad; Chapare virus (CHPV) and Machupo virus (MACV) in Bolivia; Guanarito virus (GTOV) in Venezuela; Junin virus (JUNV) in Argentina; Sabia virus (SABV) in Brazil; and 9 other species (1).
The Tacaribe serocomplex viruses (family Arenaviridae, genus Arenavirus) known to occur in Venezuela are Guanarito virus (GTOV) and Pirital virus (PIRV) (1,2).
The arenaviruses (family Arenaviridae, genus Arenavirus) known to occur in North America include Whitewater Arroyo virus (WWAV), 7 other members of the Tacaribe serocomplex (Table 1), and lymphocytic choriomeningitis virus (LCMV, the prototypic member of the lymphocytic choriomeningitis-Lassa serocomplex).
