Vanda plant white fungus on root and poss. bacterial infection on leaves

[gardeningnewbie]

Hi,

I think my vanda plant has a bacterial infection on its leaves, but I'm not sure. Also, there seems to be some white fungus/mold growing on one of the roots. Some of the roots are also brown and looks dried up. Should I take my vanda plant out of its vase and cut these roots up? Attached are some pictures.
