FREQUENCY OF ENDOBIONT IN YEAST AND YEAST-LIKE FUNGI

Abstract

The article presents the results of a study aimed at determining the occurrence of endobiont (EB) found in cultures C. albicans and from another species of fungi from Candida genus, isolated from different biotopes and to study the reason for their appearance in the fungal population. Total of 51 strains of C. albicans, 57 strains of other yeast cultures isolated primarily from patients with respiratory, digestive and genitourinary problems. The reference strains C. albicans «РКПГУ-401/885-653», С.glabrata «РКПГУ1188», С.kruseii «РКПГУ-526», С.tropicalis «РКПГУ-531», including 5 unidentified strains isolated from the environment, as well as Sacchamyces cerevisiae and S.boulardii spicies. It turned out that in all the studied cultures of yeast and yeast-like fungi isolated from different biotopes, EB was found in 100% of cases. It was also determined that EB appears in fungal populations under the influence of different factors (nutritional media, pH, temperature, cultivation time, various antimicrobial substances etc.). The results obtained confirm that the detected EB is not random, but is an endobiont of yeast and yeast-like fungi.
