title: [Tuberculin conversion rate in long-term employees of a university hospital during the period from 1975 to 1985].
abstract: During the period of 1975 until 1985 the tuberculin conversion rate has been determined for 142 persons who have been employed more than 4 years in an university hospital. The current records of the occupational medical investigation-department in which 5,700 case sheets have been stored at the beginning have been available for the selection of these subjects. After a latent period of 2.5 years 9.2% of the employees converted. The highest conversion rate of 16.7% was settled amongst those staff occupied in a lower level, e.g. craftsmen, charwomen, laundress, kitchenhelp, servants and so on. The second in high responder-quote was found in the nursing personal with 9.9% followed by the laboratory staff with 8.7%. Within the office workers no tuberculin positive reagent has been observed. Whilst the interpretation of the tuberculin conversion rate there must be taken into consideration beside the occupational dependent sensibilization against tuberculosis bacteria the non occupational contamination sources, too (like smear- and droplet infection due to usual social contacts or household-contacts resp.).
