Viral diversity and phylogeny of astroviruses from eonycteris spelaea in Singapore.

Astroviruses cause gastroenteritis in many different animals including humans. Recently, several studies conducted in China, Hong Kong and Germany detected astroviruses in bats. Bats are known reservoirs for many viruses that cause disease in humans. They harbor astroviruses but appear to be asympto...
