host and viral traits predict zoonotic spillover from mammals.the majority of human emerging infectious diseases are zoonotic, with viruses that originate in wild mammals of particular concern (for example, hiv, ebola and sars). understanding patterns of viral diversity in wildlife and determinants of successful cross-species transmission, or spillover, are therefore key goals for pandemic surveillance programs. however, few analytical tools exist to identify which host species are likely to harbour the next human virus, or which viruses can cross species ...201728636590
large serological survey showing cocirculation of ebola and marburg viruses in gabonese bat populations, and a high seroprevalence of both viruses in rousettus aegyptiacus.ebola and marburg viruses cause highly lethal hemorrhagic fevers in humans. recently, bats of multiple species have been identified as possible natural hosts of zaire ebolavirus (zebov) in gabon and republic of congo, and also of marburgvirus (marv) in gabon and democratic republic of congo.200919785757
multiple ebola virus transmission events and rapid decline of central african wildlife.several human and animal ebola outbreaks have occurred over the past 4 years in gabon and the republic of congo. the human outbreaks consisted of multiple simultaneous epidemics caused by different viral strains, and each epidemic resulted from the handling of a distinct gorilla, chimpanzee, or duiker carcass. these animal populations declined markedly during human ebola outbreaks, apparently as a result of ebola infection. recovered carcasses were infected by a variety of ebola strains, suggest ...200414726594
spatial and temporal patterns of zaire ebolavirus antibody prevalence in the possible reservoir bat species.to characterize the distribution of zaire ebolavirus (zebov) infection within the 3 bat species (epomops franqueti, hypsignathus monstrosus, and myonycteris torquata) that are possible reservoirs, we collected 1390 bats during 2003-2006 in gabon and the republic of the congo. detection of zebov immunoglobulin g (igg) in 40 specimens supports the role of these bat species as the zebov reservoirs. zebov igg prevalence rates (5%) were homogeneous across epidemic and nonepidemic regions during outbr ...200717940947
comparative phylogeography of african fruit bats (chiroptera, pteropodidae) provide new insights into the outbreak of ebola virus disease in west africa, 2014-2016.both ebolavirus and marburgvirus were detected in several fruit bat species of the family pteropodidae, suggesting that this taxon plays a key role in the life cycle of filoviruses. after four decades of zaire ebolavirus (zebov) outbreaks in central africa, the virus was detected for the first time in west africa in 2014. to better understand the role of fruit bats as potential reservoirs and circulating hosts between central and west africa, we examine here the phylogeny and comparative phyloge ...201727746072
