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.
