Ebolavirus (EBOV) and Marburgvirus (MARV) that compose the filovirus family of negative strand RNA viruses infect a broad range of mammalian cells. Recent studies indicate that cellular entry of this family of viruses requires a series of cellular protein interactions … Continue reading
When it comes to nasty pathogens, Marburg virus is among the nastiest. Cousin to Ebola virus, Marburg causes fever, rash, delirium, and severe hemorrhaging, often ending in organ failure and death. It is rare in the wild, but was a … Continue reading
Filoviruses cause lethal hemorrhagic fever in humans and nonhuman primates. The family Filoviridae includes two genera: Marburgvirus (MARV) and Ebolavirus (EBOVs). MARV was discovered in 1967 in Marburg, Germany during an outbreak in laboratory staff exposed to tissues from monkeys … Continue reading
Infections by the Ebola and Marburg filoviruses cause a rapidly fatal haemorrhagic fever in humans for which no approved antivirals are available. A new paper describes a genome-wide screen of human cells to identify host factors required for Ebola virus entry. Continue reading
Ebola glycoprotein (GP) is the only virus protein expressed on the surface of Ebola virus and mediates entry into target cells. However, several studies report that GP expression also causes cytotoxicity, although the underlying mechanism remains unknown. GP is also … Continue reading
The filoviruses, Marburg and Ebola, cause lethal hemorrhagic fever and are highest-priority bioterrorism agents. Filovirus particles contain a rod-like nucleocapsid and are normally filamentous, though other shapes are seen. It is poorly understood how such large filamentous particles are assembled … Continue reading
Ebola and Marburg virus are filoviruses that cause outbreaks of highly lethal haemorrhagic fever. Mortality rates in these diseases average more than 50%, with the highest recorded rates seen for Ebola Zaire virus (88%) and Marburg Angola virus (90%). Infection … Continue reading
