Hi Sara, last tme i went to my doctor visit to give a sputum culture i asked him to make sure they let us know the answer to that question. Well, about 3 weeks ago i went fo my follow up visit, and wouldnt you know, the cepacia didnt show up. As much as i would love to believe it is gone i know it isnt. I still run fevers almost every single day and this only started once i got cepacia. I know sometimes it doesnt always show up in cultures, especially if they dont allow it to sit long enough. I did see on my list that i am suseptible to cipro, immipenim, and pipercillin. I am taking oral minocycline, and cipro and inhaled tobi right now, along with pulmozyme. I also use my inhaler ( albuterol) twice daily, and i do the vest at least once a day, more if i feel crappy. Im taking oral glutathione now as well ( started in May) seems to have helped a LOT with my energy level. I know how frustrating it is when it seems like the best antibiotics just wont do anymore. Like i once said in an earlier post.......b. cepaca reminds me of being amongst the thickest forrest where you can see the road , but never seem to get out of the woods. When i eventually do find out what strain i have i will post it on here somewhere. take care, ~ Diane 38 cf /b.cepacia/ diabetes
