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 22.5% positive isolates originating from women and 25.7% positive isolates originating from men. They included mono-species isolates of: Rh. glutinis, Rh. minuta, Rh. mucilaginosa and two-species isolates: Rh. minuta + Candida dubliniensis, Rh. mucilaginosa + C. albicans and Rh. mucilaginosa + Saccharomyces cerevisiae. The enzymatic activity of the isolated fungi was evaluated as high and very high in the case of acidic and alkaline phosphatase, esterase lipase, lipase, as well as leucine, valine and cysteine arylamidase. The highest values were determined in Rh. mucilaginosa with co-occurrence of C. albicans and Rh. minuta with co-occurrence of C. dubliniensis. In the ontosphere of oncologic patients, the increasingly frequent appearance of the species of fungi with high and very high enzymatic activity indicates the progressing risk posed by opportunistic forms, which includes Rhodotorula species.

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. In total, 41 species of yeast and yeast-like fungi were isolated, including 34 from the respiratory and 25 from the digestive system. In the last decade, a significant increase has been noticed in the counts of fungi, especially the gastrointestinal tract, reported from people. As many as 18 species were isolated from both systems – they were predominated by fungi of the genus Candida and their perfect forms. Worthy of notice are also frequent isolations of yeast (Saccharomyces spp.) and detection of an endemic species, Paracoccidioides brasiliensis, in the respiratory system, and of the sexual stages of Rhodosporidium diobovatum and Rhodosporidium kratochvilovae from the gastrointestinal tract.
