Aquatic fungi and fungus-like organisms in the bathing sites of the river Supraśl in Podlasie Province of Poland

Studies on the occurrence of aquatic fungi in the bathing sites of the river Supraśl in Podlasie Province of northeastern Poland were conducted in the years 2001-2003. Some hydrochemical analyses were performed using standard methods. Bait method was used to isolate the fungi. The following species were identified: fish pathogenic fungi – Achlya orion, Aphanomyces laevis, Dictyuchus monosporus, Saprolegnia ferax, S. monoica, and S. parasitica; human pathogenic fungi – Aspergillus candidus, Candida albicans, Lagenidium humanum, Penicillium mycetomagenum, Rhizophydium keratinophilum, and Trichosporon cutaneum; and phytopathogenic fungi – Achlya racemosa, Pythium butleri, P. myriotylum, and P. debaryanum. Physicochemical parameters of water in the bathing sites had no important effect on the presence of fungi.
