Question What's wrong with my Onc. 'Golden Showers'?

I've got another trouble case here. My Onc. Golden Showers has been rapidly turning brown these two days, I have had it since beginning of March. Brown as in mushy brown that looks like it's from the inside of the plant. Will post a pic of it in the photo gallery tmr, named something like Onc. with problems.

The plant's my favorite, I really want to save it. Please help.

Is there a virus or infection or what?

It might be 'brown rot', a bacterial issue. You would have to remove anything brown, treat the rest with isopropyl alcohol, then look for something a bit more powerful. Brown rot does spread quickly. I have saved a cattleya with this by cutting and disinfecting with alcohol but something systemic will work faster and more efficiently. Here are some sites to help you:

Good luck! If any other orchids are nearby, it might be wise to disinfect them, too.
