Detection of Chlamydia trachomatis, Mycoplasma hominis and Ureaplasma urealyticum in pregnant Dutch women

Abstract A prospective study was performed to determine the prevalence of endocervical infection by Chlamydia trachomatis and vaginal colonization by Mycoplasma hominis and Ureaplasma urealyticum in pregnant women seeking routine obstetrical care in two clinics in the southern part of the Netherlands. C. trachomatis was detected using the direct immunofluorescence staining technique. For the genital mycoplasmata, generally accepted culture methods were used. Evaluable samples were obtained from 691 of 770 women in the first trimester of pregnancy. C. trachomatis was detected in 2.3%, M. hominis in 5.2% and U. urealyticum in 23.9% of the women. The isolation percentages of C. trachomatis and U. urealyticum were almost equally distributed in the different age groups. The prevalence of all three micro-organisms did not seem to be related to parity. Smoking and alcohol consumption seemed to influence the isolation rate of M. hominis and U. urealyticum .
