Phyllosphere of Submerged Plants in Bathing Lakes as a Reservoir of Fungi-Potential Human Pathogens.

This study analysed whether the littoral zone in the immediate vicinity of bathing sites retains potentially pathogenic yeasts on the phyllosphere surface and to what extent the species composition of microfungi in the phyllosphere and in surface waters is similar. The research was carried out in selected lakes located within the administrative boundaries of the city of Olsztyn, the largest city in the Masurian Lake District (NE Poland). The experiment was conducted in three summer seasons near bathing sites in three lakes, which are the most popular as recreational sites (Lake Kortowskie, Lake Tyrsko, and Lake Skanda).

The phyllosphere as a little-known reservoir of the Fusarium genus, a fungi of importance to medical mycology.

The phyllosphere is an ecological niche that includes the area of the leaf blade, which is a living environment for microorganisms of various taxonomic and trophic groups, including saprotrophic and phytopathogenic fungi. This study analysed the degree of colonisation of the phyllosphere of rush plants of selected bathing lakes by fungi of the Fusarium genus that are of significance to the etiology and epidemiology of fungal infections, and to toxicology and allergology. The research materials was plants of the littoral zone of Lakes Skanda and Kortowskie, which were subjected to a standard phytopathological assessment.

Fungi of the genus Rhodotorula isolated from the oral cavity of oncologic patients with colorectal cancer.

This paper concerns the frequency of occurrence and enzymatic activity of fungi of the genus Rhodotorula isolated from the oral cavity of patients with colorectal cancer. Swabs from the oral cavity were subjected to standard mycological diagnostic procedures; enzymatic activity of the fungi was evaluated using and API Zym test by BioMereux. The fungi of the genus Rhodotorula were noted in 22.

Yeasts isolated from frequently in-patients and out-patients.

The paper is a part of a general mycological monitoring study of nosocomial infections. Differences in the species composition and drug resistance of fungi isolated from in-patients and out-patients prompted an analysis of this topic. The studies were conducted with fungi from the collection of the Department of Mycology, University of Warmia and Mazury in Olsztyn, that were isolated from the oral cavity, sputum, bronchoscopic fluid, anus and skin from 100 in-patients and 100 out-patients.

Mycological monitoring of selected aquatic ecosystems in the context of epidemiological hazards. Drinking water.

Many species of microfungi are reported in aquatic ecosystems with different frequency. Their number constantly fluctuates depending on the concentration of environmental and anthropogenic factors. Drinking water, tap and bottled, is essential for the proper functioning of the human body.

Snow in the city as a spore bank of potentially pathogenic fungi.

This study evaluates the role of snow as a specific ecological niche and a vector in fungal spreading with particular emphasis on potential pathogens in seasonally and daily changing conditions. The experimental material was fungi isolated from the atmospheric air, snow cover, and fragments of ice and soil from underneath the snow cover. The total count of microfungi in the air before snowfall, i.

Results of long-standing mycological analyses of biological materials originating from selected organ ontocenoses--yeast and yeast-like fungi.

This paper reviews the results of an extensive monitoring study, spanning 20-years of observation from three medical centres in Olsztyn on the dynamics and species diversity of fungi most frequently colonizing the respiratory and digestive systems of humans. The experimental materials were swabs and specimens from the gastrointestinal tract, swabs from the oral cavity and pharynx, as well as sputum and bronchial fluid from the respiratory system. The biological material was subjected to routine mycological diagnostics, taxonomic determination and identification.
