Comparison of Zaire and Bundibugyo Ebolavirus Polymerase Complexes and Susceptibility to Antivirals through a Newly Developed Bundibugyo Minigenome System.

ABSTRACT: Members of the genus Ebolavirus cause lethal disease in humans, with Zaire ebolavirus (EBOV) being the most pathogenic (up to 90% morality) and Bundibugyo ebolavirus (BDBV) the least pathogenic (∼37% mortality). Historically, there has been a lack of research on BDBV, and there is no means to study BDBV outside of a high-containment laboratory. Here, we describe a minigenome replication system to study BDBV transcription and compare the efficacy of small-molecule inhibitors between EBOV and BDBV. Using this system, we examined the ability of the polymerase complex proteins from EBOV and BDBV to interact and form a functional unit as well as the impact of the genomic untranslated ends, known to contain important signals for transcription (3'-untranslated region) and rep
