Yes good point. The accounts I hear of that were successful in treating Pseudo do it fairly soon after diagnosis and were treated aggressively. Usually antibiotic followed by Toby inhalation for some time. Also you have to be lucky to get it diagnosed early on. How long did you do the Mero IV? Let us know what retesting shows. Curious why your Dr decided to use IV. Usually most prescribe Cipro or Levo oral. Personally I think the IV is a much better option.
