molecular diet analysis of two african free-tailed bats (molossidae) using high throughput sequencing.given the diversity of prey consumed by insectivorous bats, it is difficult to discern the composition of their diet using morphological or conventional pcr-based analyses of their faeces. we demonstrate the use of a powerful alternate tool, the use of the roche flx sequencing platform to deep-sequence uniquely 5' tagged insect-generic barcode cytochrome c oxidase i (coi) fragments, that were pcr amplified from faecal pellets of two free-tailed bat species chaerephon pumilus and mops condylurus ...201121731749
absent or low rate of adult neurogenesis in the hippocampus of bats (chiroptera).bats are the only flying mammals and have well developed navigation abilities for 3d-space. even bats with comparatively small home ranges cover much larger territories than rodents, and long-distance migration by some species is unique among small mammals. adult proliferation of neurons, i.e., adult neurogenesis, in the dentate gyrus of rodents is thought to play an important role in spatial memory and learning, as indicated by lesion studies and recordings of neurons active during spatial beha ...200717520014
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
molecular detection of viruses in kenyan bats and discovery of novel astroviruses, caliciviruses and rotaviruses.this is the first country-wide surveillance of bat-borne viruses in kenya spanning from 2012-2015 covering sites perceived to have medium to high level bat-human interaction. the objective of this surveillance study was to apply a non-invasive approach using fresh feces to detect viruses circulating within the diverse species of kenyan bats. we screened for both dna and rna viruses; specifically, astroviruses (astvs), adenoviruses (advs), caliciviruses (calvs), coronaviruses (covs), flaviviruses ...201728393313
thermoregulation in the angolan free-tailed bat mops condylurus: a small mammal that uses hot roosts.the angolan free-tailed bat (mops condylurus) uses roosts that often exceed 40 degrees c, an ambient temperature (ta) that is lethal to many microchiropterans. we measured the physiological responses of this species at ta's from 15 degrees to 45 degrees c. torpor was commonly employed during the day at the lower ta, but the bats generally remained euthermic at night, with a mean body temperature (tb) of 35.2 degrees c. metabolic rate reflected the pattern of tb, increasing with falling ta at nig ...200610438676
investigating the zoonotic origin of the west african ebola epidemic.the severe ebola virus disease epidemic occurring in west africa stems from a single zoonotic transmission event to a 2-year-old boy in meliandou, guinea. we investigated the zoonotic origins of the epidemic using wildlife surveys, interviews, and molecular analyses of bat and environmental samples. we found no evidence for a concurrent outbreak in larger wildlife. exposure to fruit bats is common in the region, but the index case may have been infected by playing in a hollow tree housing a colo ...201525550396
