[Examination of the growth of pathogenic organisms on the elastic joints made of plastic material in swimming baths (author's transl)].

Roughly three months after a swimming bath had been put into operation a growth was observed on the permanently elastic joints made of plastic material at the bottom of the pool. Samples were taken and examined and bacteria, fungi, green algae as well as many monocellular organisms were found. The repeated identification of a pathogenic dermatophyte and of P. aeruginosa was of hygienic significance.
