Summary:Factors promoting fungal contamination of the cement jointing between bathroom tiles were studied in the laboratory. Under continuous wet conditions, the growth of the yeast Rhodotolura and Candida on cement was detected from the fourth day of the experiment. Following the rapid growth and decline of the yeast, growth of the mold Paecilomyces was detected on the 12th day. The application of soap or malt extract to the cement promoted the growth of Paecilomyces. Prolongation of dry conditions delayed the growth of both yeast and mold; under these conditions, Cladosporium, one of the most common molds in household bathrooms, was detected instead of Paecilomyces. Colonies of Cladosporium were observed along cracks in the cement. On all cement examined, a succession of mycological flora from yeast to mold was found, although fungal genera varied with culture conditions.
