Proteinase secretion by C. parapsilosis. Proteinase secretion by C. parapsilosis isolates obtained from different geographical areas (A) and different anatomical origin (B). 'Liquor' refers to cerebrospinal fluid. Proteolytic activity was assessed on YCB-BSA agar after 7 days incubation at 30°C. Numbers of protease producing isolates (P) versus non producers (NP) were compared using Fisher's exact test. A P value < 0.05 was considered statistically significant. I = Italy, NZ = New Zealand, RA = Argentina, H = Hungary.
