TL;DR: The large number of ZEBOV IgG-positive adult bats and pregnant H. monstrosus females suggests virus transmission within bat populations through fighting and sexual contact and offers some insight into the appearance of outbreaks.
Abstract: 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 outbreaks, indicating that infected bats may well be present in nonepidemic regions of central Africa. ZEBOV IgG prevalence decreased, significantly, to 1% after the outbreaks, suggesting that the percentage of IgG-positive bats is associated with virus transmission to other animal species and outbreak appearance. The large number of ZEBOV IgG-positive adult bats and pregnant H. monstrosus females suggests virus transmission within bat populations through fighting and sexual contact. Our study, thus, helps to describe Ebola virus circulation in bats and offers some insight into the appearance of outbreaks.

TL;DR: The phylogenetic results confirm the existence of four independent lineages of African fruit bats and indicate that the three species suspected to represent ZEBOV reservoir hosts (Epomops franqueti, Hypsignathus monstrosus, and Myonycteris torquata) belong to an African clade that diversified rapidly around 8-7 Mya.

TL;DR: Serological screening and detection of genomic RNA indicates that members of the genus Henipavirus are present not only in Southeast Asia but also in African fruit bats, and the M74 glycoproteins show functional similarities to glycoprotein of Nipah virus.
Abstract: Serological screening and detection of genomic RNA indicates that members of the genus Henipavirus are present not only in Southeast Asia but also in African fruit bats. We demonstrate that the surface glycoproteins F and G of an African henipavirus (M74) induce syncytium formation in a kidney cell line derived from an African fruit bat, Hypsignathus monstrosus. Despite a less broad cell tropism, the M74 glycoproteins show functional similarities to glycoproteins of Nipah virus.

TL;DR: The structure of bat assemblages was studied in relation to variation in forest landscapes in four localities of the eastern Niger Delta (southern Nigeria) and various groups are interpreted in the light of the available information on the ecology and distribution of Nigerian bats.
Abstract: The structure of bat assemblages was studied in relation to variation in forest landscapes in four localities of the eastern Niger Delta (southern Nigeria). The study areas were inhabited by thirteen species, seven Megachiroptera and six Microchiroptera, among which Eidolon helvum, Hypsignathus monstrosus, Rousettus egyptiacus, Saccolaimus peli, and Hipposideros caffer were recorded for the first time, whereas Epomophorus gambianus, Scotonycteris zenkeri, Megaloglossus woermanni, Scotophilus viridis, and Mops thersites were first cited only recently. The majority of captures occurred in secondary forest habitat (99 specimens belonging to 10 species), followed by primary forest (40 specimens, 5 species), and by the bush (13 specimens, 5 species). A multivariate set of analyses arranged the various species into six ‘ecological groups’: (i) Eidolon helvum, Mops thersites; (ii) Hipposideros caffer, (iii) Hypsignathus monstrosus; (iv) Rousettus egyptiacus, Epomops franqueti, Scotonycteris zenkeri, Nyc...
