[Amoebae in swimming-pools: microbiological and epidemiological aspects (author's transl)].

An inquiry was held to determine the occurrence and quantitative importance of "Limax" amoebae in 8 swimming-pools of the North of France. The influence of water flow system, filters and water disinfectants was studied. The connections with the bacterial flora growing at 37 degrees C and the presence of strains able to grow at 41 degrees were analyzed.
