title: Immune responses to yeast and mycelial forms of Candida albicans in intraperitoneally infected mice.
abstract: Candida albicans E-139 produced pure mycelial and yeast cultures in a low sulphate medium at different temperatures. The influence of the morphological phase, dose and viability of the fungi on the kinetic of delayed-type hypersensitivity (DTH) and anti-mycelial and anti-yeast antibodies have been studied in mice injected intraperitoneally. The mycelial form elicited higher DTH levels than the yeast phase. This effect seems to be related to its antigenic properties. The effect of dose on the immune response depends on the viability of the fungus. The mycelial cytoplasmic antigens were more effective than the yeast ones in detecting antibodies induced during the experiments, particularly during the later stages of the observation periods, suggesting that such antigens may be useful in the serodiagnosis of Candida infections.
