Machupo virus was isolated and viral antigen was detected in the patients serum.
Testing for antibodies to Machupo virus was negative for each of the N rodents.
The etiologic agent, Machupo virus, is a member of the family Arenaviridae and is maintained in the rodent C.
Sequence analyses confirmed the isolates as Machupo virus (Figure).
This study confirms the long-term maintenance of distinct phylogenetically forms of Machupo virus in a small area within Beni.

Arenaviruses can be divided phylogenetically, serologically, and geographically into two major complexes: the Old World complex (e.g., Lassa virus, lymphocytic choriomeningitis virus [LCMV]) and the New World complex (e.g., Tacaribe virus, Junin virus, Machupo virus
