[Bacteriological investigations in radiological clinic (radiographic apparatus, rooms and personnel) (author's transl)].

The importance of X-ray departments as a potential source of infection with hospital organisms was investigated by examining a number of radiographic rooms and comparing these with two private dwellings. It was found that there was a higher incidence of organisms than in private homes, but this was considerably less than on wards. Particularly high numbers of organisms, including pathogenic ones, were found on radiographic apparatus which was inaccessible, and on sponge pillows. Regular disinfection reduced the number of organisms almost to the level of an operating theatre. A visit to the X-ray department does not present a significant risk of infection; nevertheless, hygiene can be markedly improved by appropriate changes in the rooms and by carrying out methods of disinfection.
