Out of the test group, 120 isolates, 98 (82%) formed (+) germ tube test (Figure 3-B) while out of the control group 37 isolates 28 (76%) gave positive results, yet this difference was not significant.

A medium size, smooth, pink colored colony, often with a darker mauve center, is presumptively identified as Candida glabrata ; thus a Rapid Trehalose test is needed (see "Limitations" below). These strains were first cultured in Sabouraud dextrose broth (SDB) for 36 hours at 35°C, then on CHROMagar plates at 30°C, 35°C and 37°C.
