Objective:To understand the situation of the pathogen and drug sensitivity in the patients of nongonococcal urethritis(NGU)in area of Chongqing.Methods:Totally 1265 specimens in the patients of NGU were collected

cultured and tested for drug sensitivity with 12 antibiotics.Results:From them

the simple pathogen infection was 546 cases(43.16%)

and two or three pathogen combined infection was 537 cases(42.46%)

182 cases(14.39%)respectively.The result of drug sensitivity showed that sensitivity of Ureaplasma urealyticum(UU)and Mycoplasma hominis(MH)to deoxycycline was the highest

then was to minocycline and clarithromycin respectively.Roxithromycin

erycin

ciprofloxacin were the highest drug resistance.Conclusions:Uu is the main pathogen in the NGU patients

and deoxycycline

minocycline and clarithromycin are the optimal antibiotics.But cultured and tested for drug sensitivity are also recommended before therapy

to getting the optimal cure efficiency and reduce the development of drug resistant strain.
