Candida lipolytica was recovered from six patients in three different clinical centers. The index isolate caused a persistent fungemia with catheter-associated Candida thrombophlebitis, the second isolate was from a polymicrobial sinusitis, and the remaining four isolates were involved in tissue colonization. These and 20 other isolates were consistent in their morphological and physiological characteristics. All formed true hyphae and blastoconidia on cornmeal-Tween 80 agar and all assimilated glucose, glycerol, and erythritol. In a murine model of disseminated candidiasis, the index isolate that caused clinical fungemia caused no mortality and produced only two lesions on a kidney, as determined at necropsy. The nine isolates selected for in vitro antifungal susceptibility studies had intermediate susceptibilities to amphotericin B but were susceptible to ketoconazole. We conclude that C. lipolytica is a weakly virulent pathogen which may require an intravascular foreign body to cause fungemia.
