My daughter who has been sick for years has just been diagnosed a month ago with pseudomonas. She took Cipro for 14 days and still has same complaints. She also has constant sinus infection, after 2 surgeries and a solid year of antibiotic treatment. They just did a new culture last week and the gram stain still showed a lot of bacteria but the culture was normal(this was while on Cipro). She has been off Cipro for about 8 days now, and another culure was done 2 days ago that again the gram stain showed alot but the culture so far is normal. Her treating dr is out of town, but another dr has told me the gram stain shows alot of bacteria and she doubts the pseudomonas is gone. That coupled with the constant sinus, she advises a long course of IV antibiotic, to be started ASAP. Can this wait until he returns? I know pseudomonas is a very serious infection, that is very hard to get rid of. What does it mean for the gram stains to show so much bacteria and the culture not? Thanks!
