I am having a hard time in identifying a Candida with microscopic morpholoy
somewhat resembles C. pseudotropicalis. The biochemical profile is, however,
not entirely consistent with that of C. pseudotropicalis. The biggest 
trouble is that it neither ferments nor assimilates sucrose. Is this 
possible for this species. Where can I find additional database for its ID? 
Both the ViTech and the API systems failed to give an ID. For those with 
database-in-brains, here's it's biochemical profile:

Fermentation:                         Assimilation:

Dextrose +                            Glucose   +
Maltose  +/-                          Glycerol  -
Lactose  +                            2-keto-D-gluconate  -
Sucrose  -                            L-arabinose  +
Trehalose +/-                         xylose    +
Raffinose -                           Adonitol(Ribitol)   +              
                                      xylitol   +
                                      galactose +
                                      inositol  -
                                      sorbitol  +
                                      Methyl-D-glucoside  -
                                      N-acetyl-D-glucosamine  -
                                      cellobiose  +
                                      lactose   +
                                      maltose   -
                                      sucrose   -
                                      trehalose -
                                      melezitose  -
                                      raffinose   +

Thank you all for your help.
