Antibodies to Tacaribe serocomplex viruses (Family Arenaviridae
, Genus Arenavirus) in Cricetid rodents from New Mexico, Texas, and Mexico.
To The Editor: Woodrats (Neotoma spp.) are natural hosts of Whitewater Arroyo virus (WWAV) and other Tacaribe serocomplex viruses (family Arenaviridae
) in the western United States and northern Mexico (1).
The causative agent of Lassa fever is Lassa virus (LASV), a member of the Arenaviridae
An etiologic agent was isolated from cerebrospinal fluid of a patient in the 2003 cluster, and identified by EM as belonging to the family Arenaviridae
. IFA assay and PCR showed that the agent was lymphocytic choriomeningitis virus (LCMV), an arena-virus transmitted by rodents (24).
Evidence suggesting the placement of viruses in families Arenaviridae
, Paramyxoviridae, or Poxviridae.
Arenaviruses (family Arenaviridae
) are primarily rodent-borne RNA viruses.
