['Sterile' brain abscesses (author's transl)]

In 16 cases of brain abscess (1970 to 1976) 10 could be identified to be bacteriologically sterile. However in 5 cases of "sterile" cerebral abscesses, where swabs were taken under anaerobic conditions, it was possible to isolate anaerobic bacteria in every case. It is concluded that in reality thse so-called "sterile" brain abscesses were also contaminated with anaerobes.
