I was told no .. BUT I always felt that my lungs were weakened by a serious bout with pneumonia in 2003. I was seriously ill for three months .. put on five rounds of antibiotics .. 3 rounds of steroids by my internist. NOT ONCE was my sputum cultured to see which antibiotic was effective against whatever bacteria was affecting me! At that point I was not educated to the point of DEMANDING a culture .. too little to late. I was SO ill! Finally was diagnosed with MAI/MAC in 2007 via a sputum culture.
