[Bacteriological and parasitological investigations in public indoor swimming baths (author's transl)].

The importance of the public swimming bath for the dissemination of Trichomonas vaginalis is disputed. 30 samples, each of 250 ml bath water from four indoor swimming baths, were examined for trichomonads. All the samples were negative. 218 smears taken from the wet places on the heated benches and other seating accommodation in these swimming baths were cultured for trichomonads and bacteria. Trichomonas vaginalis could not be demonstrated. Fecal organisms were found in 56 places, antibiotic-sensitive staphylococci were cultured from 20 samples and Ps. aeruginosa from 8. The negative tests for trichomonads suggests that the indoor swimming bath has no epidemiological importance in the dissemination of this parasite.
