[Bronchopulmonary aspergillosis in leukemia patients].

Among 180 patients with varying leukemias bronchopulmonary aspergillosis was diagnosed in 4 (2.2%). Further development of the methods for the treatment of the main disease in this category of patients permits prognosing a significant rise in the incidence of bronchopulmonary aspergillosis.

[Antibody avidity in candidiasis patients].

The properties of antibodies to Candida albicans in healthy persons, candidiasis patients and patients with somatic pathology of nonmycotic genesis were studied. Healthy persons were found to have the highest avidity of antibodies at the minimal neutralizing dose of the antigen. In all groups the titers of antibodies were inversely related to their avidity.

[Spontaneous variability in a population of Candida albicans strains].

The spontaneous variability of the populations of C. albicans strains of different genesis in the morphological properties of their colonies and in the potential of the activity of their extracellular proteolytic and phospholipid enzymes has been studied. The isolated types of colonies, differing in their morphology, have the phenotypic character of variability.
