My input also: The first time I took it they could not identify what I had from my sputum samples but I was very sick and had 4 or 5 abcess in my lungs. So my Dr decided based on the look of my sputum that I had a certain class of bacteria that would be treated by Augmentin. He was right thankfully and I did feel way better. Then about 1.5 years later I was not doing well so he had me take it again for 2 weeks. The second time it did not help much at all. That is when I suggested to my pulmo that he test me for Pseudomonas which came up positive. It is not affected by Augmentin. So you might check to see if it covers Burkholderia Cepecia (I have never heard of that).
