Candida albicans, Candida aquatica, Candida krusei and Candida tropicalis strains isolated from springs of Podlasie province

Species composition of yeast-like fungi was investigated in 2001-2003 years. Four species from genus Candida were found: Candida albicans, Candida aquatica, Candida krusei and Candida tropicalis. The occurrence of yeast was investigated, using bait and the Sabouraud methods in the fresh waters of the six springs: Antoniuk, Cypisek, Sobolewo, Smolniki, Pólko and Rybnik of Podlasie Province. The fungi were found to be the most common at eutrophized sites of the spring Sobolewo. The spring Sobolewo, as compared to remaining springs, had a considerably higher concentrations of ammonium nitrogen, phosphates, and suspended substances

Water fungi occurrence in the water reservoir in Zarzeczany of Podlasie province

Studies on the occurrence of aquatic microorganisms in the newest water reservoir Zarzeczany village were carried out in years 2001-2004. Hydro chemical analysis was performed using standard methods. Bait method was used to isolate the fungi. In the reservoir 52 fungi species were identified: fish pathogenic Achlya debaryana, A. polyandra, Aphanomyces laevis, Dictyuchus monosporus, D. sterile, Saprolegnia ferax, S. monoica, S. parasitica, human pathogenic Candida albicans, C. tropicalis and Trichosporon cutaneum, decomposing keratin Blastocladiopsis parva, Catenaria anguillulae, C. verrucosa, Catenophlyctis variabilis, Lagenidium humanum, Rhizophydium keratinophilum, and decomposing chitin Aphanomyces astaci, Karlingia chitinophila, Rhizidium chitinophilum, Asterophlyctis irregularis and Blastocladiella brytanica

ASPECTS OF ECOLOGICAL OCCURRENCES TRICHOSPORON CUTANEUM (DE BEURMAN GOUGEROT ET VAUCHER, 1909 OTA, 1915) IN WATERS NORTH-EAST POLANDS

The aim of work was settlement of occurrence of pathogenic fungus Trichosporon cutaneum in diverse ecological environments. Object to investigations farmer river Węgorapa, Supraśl, lakes of complex Mamry and Sejny group, of cultivation ponds in Popielewo and in Poryte Jabłoń a few springs of city Białystok. In investigations one used method of baits to isolated water fungus. Quality of waters determined by physico-chemistry methods. One fixed, that pathogcnic fungus Trichosporon cutaneum stepped out in waters north-east evn Poland on all investigated sites. It was developed in both strong poluted water of lakes and ponds also in good oxygened waters and springs it was too

Bioaccumulation of organochlorine pesticides in the trophic chain alga-freshwater fish

The study was carried out on the alga Chlorella vulgaris and young specimens of crucian carp Carassius carassius. The algae and fish were exposed to a pesticide gamametox powder containing 0.6% of lindane and 3% of methoxychlor. Gas chromatography method was used to determine the content of these two active substances in the material. Based on the mean lindane and methoxychlor contents it was revealed that they were bioaccumulated at different levels of the trophic chain. Their accumulation was higher in fish than in algae, which were the source of their food. Their concentration in the muscles of crucian carp was higher when absorbed from food (i.e. Chlorella vulgaris cells), than directly from water. A similar situation was observed in relation to lindane content in the liver. In the brain, however, the concentration of both pesticides was diversioned or similar. The highest concentrations were revealed in the brain of crucian carp, slightly lower in the liver and the lowest in the muscles, i.e. edible parts of fish, irrespective of the way of absorption

Zoosporic fungi growing on the specimens of certain fish species recently introduced to Polish waters

Mycoflora developing on some fish species, recently introduced to Polish waters, has not been known. The authors incubated muscles of four fish species (monkey goby, Neogobius fluviatilis; racer goby, N. gymnotrachelus; Chinese sleeper, Perccottus glenii; and stone moroko, Pseudorasbora parva caught in the drainage area of the Bug River) in water taken from 6 different places. A total of 59 fungus species were found to grow on fish muscles studied: Achlya ambisexualis, A. americana, A. caroliniana, A. crenulata, A. debaryana, A. diffusa, A. dubia, A. intricata, A. klebsiana, A. oblongata, A. oligacantha, A. orion, A. polyandra, A. prolifera, A. proliferoides, A. radioasa, A. rodrigueziana, A. treleaseana, Aphanomyces irregularis, A. stellatus, Blastocladiella britannica, Blastocladiopsis parva, Catenaria verrucasa, Cladolegnia unispora, Dictyuchus monosporus, Isoachlya monilifera, Leptolegnia caudata, Leptomitus lacteus, Phlyctochytrium aureliae, Pythium afertile, P. aquatile, P. arrhenomanes, P. butleri, P. dissotocum, P. hemmianum, P. intermedium, P. myriotylum, P. ostracodes, P. periplocum, P. tenue, Rheosporangium aphamidermatus, Rhizophlyctis hirsutus, Rhizophydium laterale, R. macrosporum, Saprolegnia asterophora, S. diclina, S. eccentrica, S. ferax, S. hypogyna, S. litoralis, S. mixta, S. monoica, S. parasitica, S. pseudocrustosa, S. shikotsuensis, S. torulosa, S. uliginosa, Thraustotheca clavata, Zoophagus insidians. The results obtained may be important to ichthyopathologists, because 25 of the above-mentioned fungi are known as necrotroph or parasites of fishes
