Blocking the spread of Marburg virus (IMAGE) University of Pennsylvania Caption Marburg virus-like-particles (in green, which are not infectious) "bud," or exit from the surface of a host cell. A host protein (in yellow) helps the VLPs bud. Research by Penn Vet researchers and colleagues have identified a compound that can reduce the ability of the Marburg virus to spread in an animal model by blocking the host-viral interaction.
