Having urine infection since about a month. Took several antibiotics after consultation with doctor but they all show effect only for starting 2 days and then that antibiotic doesn't work. I have taken sporidex 500, zefu cv 500, norflox 400, levofloxin, cefodoxime (each taken for atleast 4-5 days). All work for starting two days then no effect and infection starts to increase. Urine culture report is attached. Kindly suggest medication since problem is increasing day by day.
