Isolation and characterization of adenoviruses persistently shed from the gastrointestinal tract of non-human primates.

Adenoviruses are important human pathogens that have been developed as vectors for gene therapies and genetic vaccines.Previous studies indicated that human infections with adenoviruses are self-limiting in immunocompetent hosts with evidence of some persistence in adenoid tissue.We sought to better understand the natural history of adenovirus infe
