| contents | <p><em>Ureaplasma</em> spp., commonly identified in the vagina/cervix of pregnant women with spontaneous preterm delivery, are the most frequently detected microorganisms in amniotic fluid. To date, 14 <em>U.</em> spp. serotypes have been characterized; however, modern molecular biology methods can distinguish different <em>U.</em> spp genotypes. Considering these factors, a knowledge gap exists regarding the association between <em>U.</em> spp. genotypes and the risk of the ascension of <em>U.</em> spp. from the cervix to the amniotic cavity. To fill this gap, an expanded multilocus sequence-typing scheme of <em>U.</em> spp. was performed to assess the relationship between cervical and amniotic fluid <em>U.</em> spp. in pregnant women with spontaneous preterm delivery. This study included 109 and 69 pregnant women with spontaneous preterm labor (PTL) and preterm prelabor rupture of membranes (PPROM), respectively. <em>U.</em> spp. DNA in cervical fluid was identified in 49% and 55% of the women with PTL and PPROM, respectively. The concurrent presence of <em>U.</em> spp. DNA in amniotic fluid was observed in 17% and 59% of the pregnant women with PTL and PPROM, respectively. Among pregnant women with PTL and PPROM, 38 expanded sequence types of cervical <em>U</em>. spp. were identified. No associations were observed between specific genotypes, subgroups, or clusters of cervical <em>U.</em> spp. and the presence of amniotic fluid <em>U</em>. spp. in pregnant women with spontaneous preterm delivery.</p> |
