3+ K pneumoniae rating here as well. I've tried many options and nothing has worked. Have taken Uva Ursi (highly effective as indicated on lab sheet) and it seemed to do nothing. Have taken probiotic for months and no difference. I'm beginning to think a bacterial biofilm is resisting Antibiotics (uva ursi in this case) and Klebsiella pneumoniae is said to be very stubborn to begin with
