I see from your previous posts that Achromobacter has been with you for a while - @pamelasc1 reported a few months ago that she had tried a specific drug that worked. See https://connect.mayoclinic.org/discussion/mycobacterium-avium-complex-pulmonary-disease-macmai/?pg=577#comment-433916

Serratia bacteria are ubiquitous - and are often found in the sinuses - I'm not sure about treatment protocols, or which antibiotics they are sensitive to.

What does the doc say about treatment options for these?
