Dr. Roach: Unusual bacteria targets weak immune systems Keith Roach View Comments Dear Dr. Roach: I was just diagnosed with nocardiosis. Not knowing anything about it, I started to do some research and, like in most cases, going to the internet really didn’t help. My pulmonary doctor didn’t tell me much except to put me on sulfamethoxazole drugs. I reacted poorly and was switched to minocycline. Are there any diet changes I should be aware of, or life changes? Should I get rid of the 28 houseplants I have in my apartment? I was surprised to find a group page on social media. It is more widespread than I was aware of, but there seems to be very little information on the harmful effects and guidelines to follow.
