| Abstract: | This study was carried out to determine whether Candida albicans infection has a suppressive effect on the immune response in mice and, if so, whether the suppressive effect influences the response towards T-dependent or T-independent antigens. ICR mice were injected with SRBC with or without C. albicans, or with bacterial LPS with or without C. albicans. The immune response of the mice towards SRBC or towards the LPS was compared by the assay for PFC, hemagglutination and hemolysis tests. The results showed a decrease in the number of PFC in spleens of mice inoculated with SRBC and C. albicans as compared to mice inoculated with SRBC alone, but no decrease in animals injected with LPS and C. albicans as compared to those immunized with LPS alone. No significant differences in the titers of hemagglutinins and hemolysins in sera of mice inoculated with SRBC or with SRBC and C. albicans were observed. C. albicans infection had no effect at all on the hemagglutinins and hemolysins titers in sera of mice inoculated with LPS. These data indicate that C. albicans affects the early phase of the immune response primarily towards T dependent antigens. |
