[Mycological studies of patients with hemoblastoses].

40 patients with haemoblastosis were examined clinically and by cultures for presence of yeast mycosis. Moreover, we analyzed specific antibodies with the help of cell agglutination, the passive haemagglutination and the precipitation using Candida antigen. 29 test persons were found having a yeast mycosis, 3 patients without clinical symptoms in pharynx showed presence of yeasts by culture, 8 test persons were clinically and mycologically negative. In cell agglutination we recorded titres of less than 1:20 to 1:5 160 and in haemagglutination titres of less than 1:20 to 1:5 160 and in haemagglutination such of less than 1:20 to 1:320. 5 patients showed positive precipitation reaction with antigen extracted of membranes of Candida albicans cells. We observed different titre motions with these patients: during illness the titre either rised or decreased clearly, or the patients were in a condition of humoral anergy against the Candida albicans antigen. It is hinted at the necessity to watch over susceptible patients mycologically.
