A Human Fallopian Tube Model for Investigation of C. trachomatis Infections
Published on: August 11, 2012
Objective:
To explore the relationship between genital infections with chlamydia trachomatis (CT) and ureaplasma urealyticum (UU) and tubal pregnancy.
Methods:
34 patients with tubal pregnancy (case group), 28 women undergoing tubal ligation (control group A) and 40 women with normal early intrauterine pregnancy (control group B) were investigated as a case-control study. The polymerase chain reaction (PCR) technique was used to detect CT DNA and UU DNA in samples from the secretion of cervix, fallopian tube and pelvic fluid.
Results:
Case group was more likely to have detectable CT DNA (47.1%) and UU DNA (55.9%) from cervical secretion than control group A and B (P < 0.05). CT DNA detective rate from fallopian tube was significantly higher in case group than the control group A (26.5% versus 3.6%, P < 0.05). There were no significant differences in the positive rates of UU DNA from fallopian tube, CT DNA and UU DNA from pelvic fluid between case group and control group A.
Conclusion:
There is a strong association between tubal pregnancy and genital infection with CT and UU.
