Nosocomial and endemic infections with a genome type of adenovirus type 5.

A unique genome type of adenovirus 5 was isolated from 37 specimens of 25 patients. DNA restriction analysis was performed with seven endonucleases. Part of the patients were treated at a bone marrow transplantation unit in Munich. Nosocomial spread, rather than activation of endogenous adenovirus infection, was likely for many of them. In addition, sporadic cases suggested an endemicity of this genome type in Bavaria.
