Scientists discover new species of Ebola virus
November 21, 2008Scientists report the discovery of a new species of Ebola virus, provisionally named Bundibugyo ebolavirus, November 21 in the open-access journal PLoS Pathogens. The virus, which was responsible for a hemorrhagic fever outbreak in western Uganda in 2007, has been characterized by a team of researchers from the Centers for Disease Control and Prevention in Atlanta, Georgia the Uganda Virus Research Institute; the Uganda Ministry of Health; and Columbia University.
Ebola virus infection in humans causes severe disease for which there is presently no vaccine or other treatment. Case fatalities range historically between 53 and 90%. Therefore, research efforts into the Ebola virus genus and potential diagnostics are ongoing, with the discovery of Bundibugyo ebolavirus representing one of the latest pieces added to this puzzle.
Knowledge of this sequence then allowed for the rapid development of a sensitive molecular detection assay which was deployed to the field as part of the outbreak response. This draft sequence also allowed for easy completion of the whole genome sequence using a traditional primer walking approach and prompt confirmation that this virus represented a new Ebola virus species. Current worldwide efforts to design effective diagnostics, antivirals and vaccines will need to take into account the distinct nature of this new member of the Ebola virus genus.

Penn Study Identifies How Ebola Virus Avoids the Immune System
Researchers at the University of Pennsylvania School of Medicine have likely found one reason why the Ebola virus is such a powerful, deadly, and effective virus. Using a cell culture model for Ebola virus infection, they have discovered that the virus disables a cellular protein called tetherin that normally can block the spread of virus from cell to cell.

Ebola by Dr. William Close (Author) IT STRIKES WITHOUT WARNING--A HORRIFYING, LETHAL DISEASE WITH NO NAME. AND NO CURE. . . . Now, from the molten center of the "hot zone," comes a terrifying, completely authentic novel of medical suspense by William T. Close, M.D., the American physician who lived in Zaire for sixteen years, and who worked desperately to contain the first outbreak of the virus in 1976. Haunted by the images from this wrenching time, and unable to forget the people he knew and lost, Dr. Close was compelled to tell their story. EBOLA, inspired by his personal experience and based upon extensive research, is an unforgettable portrait of this devastating drama, which all began with an invisible, unknown killer . . . .

NOVA: Ebola - The Plague Fighters Starring: Nova Directed By: Nova Enter the "hot zone" of one of the most frightful diseases on the planet- Ebola. When a dreaded outbreak of the deadly Ebola virus swept through a remote region of Zaire in May 1995, NOVA was the only film crew permitted into the "hot zone." Spending a total of four weeks in the quarantined city of Kikwit, the result is unprecedented journalistic coverage of this grim battle against one of the world's most lethal diseases. The Ebola plague kills a very high percentage of its victims (77% in Kikwit), often by dissolving their internal organs and connective tissue. Learn how disease specialists traced the origins of the outbreak by compiling a complete "chain of death" of the epidemic, and why they fear a mutation of Ebola will emerge that is even more difficult to contain. |

Emerging Viruses - AIDS, Ebola & Vaccinations [VHS] Starring: Len Horowitz This video is a classic. Based on the best-selling book by the same name, Dr. Len Horowitz presents the definitive exploration into the origins of the AIDS and Ebola viruses. Claims that these "emerging viruses" naturally evolved and then jumped species from monkey to man are laughable in light of the documented evidence in this extraordinary television program. These bizarre germs were undoubtedly man-made creations, accidentally or intentionally transmitted via tainted vaccines in the U.S. and Africa. The genocidal theory of AIDS is meticulously explored within the social and political context of this stormy period of American military science. This television program exposes the potential motives of administrations responsible for this atrocity, and the methods they continue... |

Ebola: Through the Eyes of the People by William T. Close (Author) At a Catholic Mission in Yambuku, an oasis of peace and efficiency in northern Congo's vast jungle forests, Mabalo Lokela, a teacher, receives an anti-malarial shot for a raging fever and headache. Sister Lucie, a Flemish nursing sister, swishes out a syringe with a weak disinfectant. The next patients are injected with the same syringe and the sick man's virus spreads. Lokela was the first Congolese victim of a new African hemorrhagic disease that became known as Ebola fever. When Sister Lucie dies a few days later, panic erupts and hospitalized patients flee into the forest. With the convent connected to the outside world by a single primitive radio, the mission nuns can only pray and wonder if anyone will act on their cries for help. |
