Lifelong persistent infection of hamster brain by human adenovirus type 6.
To establish an experimental persistent infection of the brain with human adenoviruses, adenovirus type 6 (ad 6) was inoculated intracerebrally into young adult hamsters. Hamsters appeared languid for a few days after inoculation, but recovered rapidly. By cocultivation of tissue fragments with HeLa cells, ad 6 was always recovered from the brains of hamsters throughout their lives, as long as 29 months, indicating the establishment of a lifelong persistent infection. Except for the first few days after inoculation, however, attempts to recover virus by inoculation of tissue extracts onto HeLa cells or by cultivation of tissue fragments alone were unsuccessful.
