Systems for yeasts identification and susceptibility testing.

Integral System Yeasts Plus is a 24 wells system containing biochemical substrata and dried antimycotics for the identification of the most clinically important yeasts and sensitivity evaluation to antimycotics.

The system is inoculated with the cell suspension and incubated at 36 ± 1°C for 48 hours.

Integral System Yeasts Plus allows:

• Presumptive Identification: It is based on assimilation reactions of sugars; the tests for the assimilation reactions are interpreted by evaluating the color change of wells 1-GLU to 12-DUL. The combination of positive and negative reactions allows the formation of a numerical code which permits to identify the yeasts under examination, through the use of the Table of Codes.

The well 13-CHR contains a chromogenic substrate that permits to differentiate some yeasts by evaluating the color change of the well.

• Sensitivity to antimycotics: The tests are evaluated according to growth or inhibition of yeasts in media containing the antimycotic and a growth indicator in the wells 14-NY to 23-FLU. The color change from red to orange in the wells indicates a slow growth of the yeast under examination and an intermediate sensitivity to the concentration of antimycotic in the well. The color change from red to yellow in the wells indicates a growth of the yeast under examination and resistance to the concentration of antimycotic in the well.

No color change in the well indicates no growth of the yeast under examination and sensitivity to the concentration of antimycotic in the well.

The well 24-Growth does not contain antimycotics, it contains culture medium and indicator and it works as growth control.
