ABSTRACT

Objective To analyze the infection status and variation tendency of chlamydia trachomatis (CT) ,Neisseria gonorrhoe-ae(NG) and ureaplasma urealyticum(UU) in female genital tract in northeast Sichuan province during 2005 -2012 to provide the laboratory basis for their diagnosis and treatment Methods The real-time fluorescent quantitative PCR (RT-PCR) was applied to detect the CT DNA ,NG DNA and UU DNA in 1 386 samples from female genital tract and the detection results were performed the statistical analysis .Results The total positive rate of these 3 kinds of pathogens was 62 .8% (871/1 386) .Among the simple in-fection ,UU had the highest positive rate(48 .0% ,665/1 386);the positive rates of CT and NG were only 2 .2% .In the mixed infec-tion ,the positive rate of CT + UU was highest(6 .5% ,90/1 386) ,while which of UU + NG ,CT + NG and CT+ NG+ UU was 2 .5% (35/1 386) ,0 .4% (5/1 386) and 1 .1% (15/1 386) respectively .In different age groups ,the positive rate in the age 20 years old groups were all more than 60% .The positive rate of the CT ,NG and UU pathogens in females was in continuous high level during 2005 -2012 ,and which totally showed an increasing tendency . Conclusion CT and UU are the main pathogens in female genital tract infection in this region ,and the positive rate of genital tract infection in females aged more than 20 years is higher ,the infection rate of these 3 kinds of pathogens demonstrates the increasing trend year by year ,so more attention should be paid to the detection of CT and UU in this group for guiding the clinicians to con-duct the diagnosis and treatment .
