A collaborative team of scientists reported findings today demonstrating the presence of Marburg virus RNA genome and antibodies in a common species of African fruit bat (Rousettus aegyptiacus).Appearing in the open-access scientific journal PLoS ONE, the study is the first in which RT-PCR and serological findings have both affirmed Marburg infection in a specific bat species. The natural reservoir for Marburg virus has been the subject of much speculation and scientific investigation. In demonstrating evidence of infection in this common species of fruit bat, the paper provides new insight into a deadly disease that has long baffled epidemiologists, ecologists and virologists, and in which the public has shown a sustained interest.
