Specific antibody response in a patient with Candida dubliniensis fungemia

We report a case of fungemia caused by Candida dubliniensis in a non-HIV infected patient. Multiple cultures of blood performed over a period of 13 days were positive for this recently described yeast species. The C. dubliniensis isolates recovered were susceptible to fluconazole in vitro and the patient responded to intravenous therapy with this antifungal agent. It was possible to differentiate the fungemia caused by C. dubliniensis in this patient from that caused by C. albicans in other patients on the basis of the analysis of the antibody response since the C. dubliniensis-infected patient exhibited a characteristic and specific antibody response against a cell wall component of 160-170 kDa.
