Journal ArticleDOI

Bausch,Hervé Zeller,Herwig Leirs,Herwig Leirs,Leo Braack,Modeste L. Libande,Sherif R. Zaki,Stuart T. Nichol,Thomas G. Ksiazek,Janusz T. Paweska +18 more
TL;DR: Marburg virus nucleic acid was found in 12 bats, antibodies were found in 2 species of these bats, but no live virus was isolated.
Journal ArticleDOI

TL;DR: Since multiple genetic variants of virus were identified, ongoing introduction of virus into the population helped perpetuate this outbreak, implying that reservoir hosts of Marburg virus inhabit caves, mines, or similar habitats.
Journal ArticleDOI
Mosquito-borne arboviruses of African origin: review of key viruses and vectors
Leo Braack,A. Paulo Gouveia Almeida,A. Paulo Gouveia Almeida,Anthony J. Cornel,Anthony J. Cornel,Robert Swanepoel,Christiaan De Jager +6 more
TL;DR: The conclusion reached is that increased human population growth in decades ahead coupled with increased international travel and trade is likely to sustain and increase the threat of further geographical spread of current and new arboviral disease.
Journal ArticleDOI
Community dynamics of carrion-attendant arthropods in tropical african woodland.
TL;DR: Succession at carcasses is viewed as being inherently different from the traditional concept as the habitat is non-replenishing and does not lead to a climax community.
Journal ArticleDOI
Coronavirus Antibodies in African Bat Species
Marcel A. Müller,Janusz T. Paweska,Patricia A. Leman,Christian Drosten,Klaus Grywna,Alan Kemp,Leo Braack,Karen Sonnenberg,Matthias Niedrig,Robert Swanepoel +9 more
TL;DR: Asian bats have been identified as potential reservoir hosts of coronaviruses associated with severe acute respiratory syndrome (SARS-CoV), and African bats may harbor agents related to putative group 4 CoV.
