Development of a minigenome system for Andes virus, a New World hantavirus.

The development of reverse genetics systems for negative-stranded RNA viruses is a rapidly evolving field that has greatly advanced the study of the many different aspects of the viral life cycle. Andes virus (ANDV) is a highly pathogenic hantavirus found in South America that causes hantavirus pulmonary syndrome but to date remains poorly characterized due to the lack of a reverse genetics system for genetic manipulation. Here, we describe the first successful minigenome system for a New World hantavirus, as well as many of the obstacles that still exist in the development of such a system.
