Tales of mice and men: Natural History of Arenaviruses

RESUMEN

Nowadays, Arenaviruses are among  the most feared viruses due to their potential as weapons for bioterrorism purposes. This potential is based on their increasing diversity and the fact that they are carried by rodentswhose biologic success compares only wit insects and humans. The prototype of this family is  Lymphocytic Choriomeningitis Virus which has been and excellent tool for a myriad of discoveries in immunology. Arenaviruses have been known for over 70 years but the number of members of the family is growing thanks to their insidious subsistence in third world countries and to the nature of their   genome, that makes of them sorts of skilful machines for evolution This review collects some of the work of the authors about the best-known features described for this group of viruses, among the many still-to-be discovered characteristics of this puzzling, and hard-to-study, group of zoonotic viruses.
