systemic candida infection. Cytoplasmic antigens, allergens obtained from the content
of cytoplasm C.Albicans after the separation of the cell walls, were used by many
researchers for the immunodiagnostics of candida infection [8].
Other direction of the researches on the elaboration of the diagnostic preparations
is the separation of Candida fungi ferments. There is a hypothesis, according to which
the ferments are the factors of aggression and invasion of the potentially pathogenic
Candida fungi. Many researchers outlined and studied in detail the substrate specificity
of the extra-cellular and cellular proteinases of different stocks of C. albicans. It was
found that the difference of acidic proteinases released by most Candida stocks,
reflects the degree of virulence for human. The proteinases of Candida fungi,
according to their influence on the substrates and relation to the inhibitors, are strain-
specific, however, the structural differences between enzymes are inessential.
Antibodies to the proteinases possessed the ability to react with the proteins of different
stock but of one and the same type [1, 8].
The use of different types of Candida fungi as the resource of antigens, allergens
is one more direction of the research. It is widely recognized that C. albicans is the
most frequent trigger of candida infection. However, the candida infections may be
seen in the other types of Candida fungi, mainly, C. krusei, C. parapsiosis, C.
tropicalis and C. guilliermondii. The cross reactivity of antigens, allergens of different
types of Candida creates additional difficulties during the selection of the allergens
resource. Some authors suggest obtaining the antigens from the mixture of fungi, others
- only from C. albicans, still others from the auto-stock.
Thus, the whole diversity of immunological preparations may be combined into
four categories: Allergens which contain complete particulate antigens, allergens from
separate fungi fractions, allergens for which main active ingredient is represented by
the fungi metabolism products, and allergens which include both the fungus cells
materials and the metabolsim products [4, 5].
Thus, the analysis of the references showed that the researches on the
development of antigenic and allergic preparations for the immunodiagnostics of
candida infection have been conducted intensively, but as of today, there no
preparations specific and sensitive enough [8].
The development of the technology of obtainment the proteins and
polysaccharides of C. albicans fungus cells.
Grounding of extraction agents for the obtainment of proteins and
polysaccharides from the Сandidaalbіcans fungus biomass. To determine the
optimal extraction agent to receive the protein and polysaccharides of C.albicans we
conducted the extractions in parallel with the use of several extraction agents with
regard to all technological aspects and with further analysis of biochemical
