I was given cefalexin tabs and levofloxacin tablets for another treatment.will this work thanks [/INST] Hello mentioned that you took AZITHIOPRIM for 12 days and still positive. At present, you are taking cephalexin and levofloxacin for typhoid fever. Positive cultures of blood, stool or other specimens are required for diagnosis. Stool culture remain POSITIVE for 4-5 weeks and-in rare cases of chronic carriage -for > 1 year.However, TIDAL tests remain positive for > years even after one year of successful treatment. Strain 1:160 counts as POSITIVE, while less than this is negative. When such resistant case visit my clinic I advise my patient to take AZITHROMYCIN 1gram/ day orally for 5 days (standard therapeutic dose).  Or High-dose CIPROFLOXACIN 750 mg orally twice in day for 10-14 days. Dexamethasone may be of benefit in severe cases. Hope this will help you. </s>
